weather will have a change of heart and provide us with a dry and warm (I won’t go as mad as saying hot!) summer to enjoy the fun and frolics which lay ahead. Hot on the tale of the National race meeting on the predominately land based circuit at Magnolls Farm, comes the watery pleasantries of Rother Valley Country Park. Would anyone looking to arrive late to Rother Valley contact Lee Willars direct (see the advert within for Lee’s email address) to make the necessary arrangements. Thus helping keep relations with the Park owners on a nice even keel for Lee. June will see The Big Lake Extravaganza come to life, with a week of fun for ALL hovercraft enthusiasts. See the report within on the trials undertaken by the Midlands Branch. In our search to keep the HCGB
members informed of all things Hovercraft around the world Dave Reyburn returns with more news from the USA. Also the Dutch Hovercraft club have sent us an informative newsletter, which tested our translation skills out to the max…. well Google’s! As you may have seen/read on the Forum page, Tony Broad and the North West Branch have given us a platform to attend the Pageant of Power. This undoubtedly is a great opportunity for us, which will need support. This platform should give us a great opportunity to show crowds (and organisers) what we can do, and what we are about, with a view to trying to return there on a larger scale for the following year. Thanks for the continued support members, keep sending us stuff…. enjoy!

‘Twas the night before Magnolls Farm, when all thro’ the house not a creature was stirring, not even a mouse; (except for panic stricken Hovercraft racer in the garage….) The spare skirts were stored in the camper with care, in hope that not too many disappear over the Lancashire dales; The children were nestled all snug in the car, saying ‘are we there yet!!!’ for the 27th time, While visions of the telegraph pole turn danc’d in your head….. And yes after months of waiting and anticipation, the racing season commences with the annual visit to Peaches Pad. No doubt many people have been working through the night in the last few weeks, asking themselves why they didn’t consider doing this back in October!!!! With a full action packed summer ahead for both racers and cruisers, I’m certain I’m not alone in hoping the

The Chairman’s Desk Chapter Twelve, Obviate
It is 4.30am, the morning after leaving the Hovershow. If you have never been, it is a terrific collection of hovercraft and display material from all ages of the development and evolvement through the commercial and into the more recent. The dedication of the volunteers is immense. I met Warwick, Chris, Ben and Steve amongst the many that spend their efforts trying to maintain an un-funded Museum so that future generations will know about these fantastic machines. They need your help to continue to do this. The Hovercraft Challenge to Youth is continuing its advance towards the autumn start of the builds. Les Bran and Slap have completed the build of the prototype craft and I understand the skirt will be on it shortly for the test flights and photo shoot. It may even make a guest appearance at Blackburn. The Young Engineers movement is backing the project as well. There are a group of members who are currently composing the structure of a ‘Coaching Certificate’ for the club for those who wish to attain a recognisable standard of competency in teaching others a safe method of controlling a hovercraft. We are planning a ‘Teaching Hover-in’ staged later this year, to enable youth group leaders (including scouts, cadets etc) to understand more about the safe build and use of hovercraft. Deborah Hunt and Gill Crane have joined the Hoverclub of Great Britain council and are a very welcome addition. Gill is more normally seen in the role of a very orange and enthusiastic marshal at race events and Debs can instil control over the Bearwood team (and Keith) with a raise of her eyebrow. They will be having their first meeting with the rest of the Council at Peaches Pad this coming weekend. There is a great deal of interest in Little Scrapper 2 at the moment. Sandy, wife of the late Barry Staples, donated a craft called little Scrapper to the Midlands Branch who used it as a loan craft for new members to have a taste of racing. Dan Turnbull, with some donated parts and effort, has built a newer replacement. If any member wishes to use this, please contact Dan. The Hovercraft Extravaganza at Nottingham is rapidly approaching. Keith Rhodes and team need to know the numbers of people who will be entering the Endurance Race and the Speed Trials. May 20th is the closing date. If you are taking part, please make sure that you complete the entry form of the club website in the club shop section. This will be a fun year. If you wish to discuss anything, my contact details are at the back of the magazine. Chris This much loved ‘vintage’ or collectors (1984) item of a home-on-themove is up for sale. Lovingly created into a dual purpose vehicle, it will take a hovercraft to and from meetings or cruises and keep it’s owners warm and dry. It is experienced in travelling in Europe, having been to the German and French and Swedish World Championships. This home from home is endowed with a spare wheel, double bed which converts to bench seating, two gas rings, 3 way fridge, is wired for TV via satellite dish (TV and set-top box not included), has a mains socket, bathroom and one gas bottle will be included. The caravan is suitable for tall people, it has very large windows giving plenty of light during the day and making it ideal to sit up in bed in the morning and watch the world go by. The dining table will accommodate 4/5 at one sitting. For further information contact Bob Coles on 07764617894 www.hovercraft.org.uk
The Council of The Hovercraft Club of Great Britain Council meeting 244 - Conference call on Wednesday 28 March 2012 at 10:00am Ref.
Apologies: Tony Drake (President)
Members present: Chris Daly, Kevin Foster, Jim Lyne, Roger Morton, Carla Thomas. Chris led all present in welcoming Carla as a member of council.
Co-option of council member(s): Gill Crane and Deborah Hunt had offered to join council. Agreed by all that both should be co-opted.
Election of officers: Chris Daly – Chair, Press & public relations. Kevin Foster – Vice chair, Insurance officer. Roger Morton – Secretary. Paula Broad – Treasurer (not a member of council).
Minutes of Meeting 243: Had already been approved by email.
Matters’ arising: All related to on-going matters included in the agenda for discussion.
Coaching certificate / Instructors licence: Ewan Black had drafted a paper on the proposed Hovercraft Coach Award. This is a work in progress An informal group would be helping Ewan to take this forward. Council also discussed the possible need for CRB clearance for HCGB members working with young people.
Annual General Meeting: The 2012 AGM was agreed to have been a great success. Jo-Anne, Del and the Meercats did a great job. Carla offered to take on the organising of the 2013 AGM.
Increasing Non-Competitive Activity: Council discussed the need to re-form a recreational committee. It was agreed that we lacked the depth of volunteers to make this happen. For 2012 we will have an informal structure, whilst encouraging people to organise events. Carla agreed to own this on behalf of council. We also need to consider an update of the non-racing rules, regulations and scrutineering. Kevin and Jim offered to look at this.
The club website: Carla and Roger offered to help with updating the club website, to a design by Louise.
The information trailer / club shop: Jo-Anne has arranged to pick up the trailer. Her first event will be the Cullompton College Hovergo Day. She is also working on the new on-line shop for club merchandise.
The Challenge to Youth: Good work has been done in pushing out leaflets but the prototype craft is not quite finished (it is hoped that it will be on show at Cullompton). It was agreed that we could cover the 2013 series from club funds. It was also agreed that we should get the prototype craft to all possible race meetings and invite potential entrants to see the craft, see the racing and camp for the weekend.
The College Challenge: Jim had publicity ready to send out the next day. He saw the College Challenge, which is aimed at 16 to 19 year olds, as an encouragement to build craft to race as novices at regular race meetings (not to have a dedicated race meeting). It was agreed that the challenge would be opened to apprentice groups as well as colleges and that we would invite staff and managers to 2012 race meetings to see what goes on.
Recruitment of new members: Bob Beech has arranged surgery for his knee and expects to be ready to give rides this season. We will make the same offer as in 2011 – a year of club membership will be included in the price of a ride. Branches organising race meetings would be encouraged to invite Bob to attend and give rides. Chris’s company is offering a deal of membership plus a lesson, marketed via Groupon. Many members recruited through these initiatives would not renew but if even a percentage subsequently became full members it would make a big difference to the club.
Any other business: None raised.
Next meeting: A brief face-to-face meeting at Magnolls Farm on Saturday 5 May 2012.
Cholomondeley Castle Pageant of Power 15th – 17th June 2012 Taking place in the glorious grounds of Cholmondeley Castle the Pageant combines speed, nerve and flair with exceptional design and engineering. Since 2008 it has been the ambition of the Pageant of Power to showcase the best of historic and contemporary automotive power, whether on Land, Sea or Air. This is a major motorsport event in the North West attracting over 40,000 visitors last year. We have been invited to take part and feature both Racing and Cruising Hovercraft on the large lake inside the main event arena. This is a fantastic opportunity to show people what we do so well and promote our new hovercraft challenges. The plan is to run the event as a Summer Hover-In, demonstrating both Racing and Cruising Hovercraft on the large mere and small land section. We have plenty of time slots (see programme below) Corporate hovercraft will also operate giving rides for the public too. Any driver bringing a hovercraft or any officials will have free camping, free food and drinks (Breakfast, Lunch and Dinner both Sat and Sun in a dedicated Marquee arranged by the lake organiser) and wristband for the weekend to see all the attractions. For any family/friends £15 will give them the same food, camping and wristband deal, £10 for children. We will also have our own access gate, more details nearer the time.

Briggs & Stratton – Exciting Dyno development of the Vanguard 35bhp! If there’s two businesses that attract more ‘optimistic’ claims than engine tuning and hovercraft, then I don’t know what it is! Attacking estate agents and double glazing salesmen is a bit last century and bankers seem to have avoided much of what they are due. Anyway – on the basis that all claims (especially commercial ones) should be proven, we decided to dyno test three of the engines we use in our range of commercially built hovercraft. Partly, this was to get factual figures that allow us to best match fan design to engine power curves, and partly because we like having proof that our products do what we claim! The backbone of our business is the Marlin II which is a 2/3 seat cruising hovercraft. It’s designed to be a ‘sports cruiser’ - fun to drive, with good performance, but good for long distance cruising. It uses the Briggs & Stratton Vanguard engine which is an air-cooled V-Twin, in this case, the 35bhp rated version. To develop and test engines, we went to OO Racing in Sandwich. Adrian the proprietor is a specialist in small four stroke engines, very well respected for his experience and development skills, equipped with a dynamometer and conveniently nearby our new factory! What we’re chasing is decent amounts of torque rather than the ‘headline grabbing’ bhp figure. Torque is the true measure of the ‘turning force’ of an engine which is absolutely crucial in a hovercraft engine. This is because hovercraft do not use a gearbox - instead they have a simple transmission and a fan which provides a fixed load. With a ‘peaky’ or high revving engine such as a two-stroke, response can be poor as you cannot select a lower gear to multiply the available torque like you can with a motorbike or car engine. So, the goal of a hovercraft engine is a flat torque curve for good response and easy cruising at speed. First up, we tested a bog standard, brand new, straight-out-the-box LightHovercraft 08
engine to see if it really does produce the full measure of 35bhp! It’s been suggested (and I’ve seen a power curve) suggesting that it only produces 31bhp. However, our fan data has always suggested that it’s producing near its claimed power figure. We wanted to find out once and for all. First test….
extensively in the USA to power the ‘mud buddy’ boats that are used in swamps – and there’s lots of tuning parts available to take them to (we’re told) more than 80bhp.
Stock Engine : 35.4bhp at 3668rpm and 56lb/ft of torque at 3167rpm.
Maximum Torque 70lb/ft at 3200rpm
A good start then! Spot on what B&S claim. Next we fitted the ‘Savage’ engine. This is our ‘stage one’ upgrade to the engine. Again, this was a brand new engine, which has some light modifications undertaken to sharpen up throttle response and add more torque. Another good result, an impressive 9lb gain in torque coupled with a 2bhp gain in peak power but all at lower revs. Savage 37bhp at 3493rpm (170rpm lower than standard) and 65lb/ ft at 2544rpm (600rpm lower than standard!) These figures really support the fact that when fitted to a hovercraft it feels ‘sparkly’ in comparison to the standard engine, cruises easily at very low throttle settings, and pulls to maximum revs quicker and more cleanly. So, to the big one! We’ve developed the ‘Rampage’ engine over the course of the last year and have had it fitted to a development craft in order to get some time on it. Of the three engines, this is the only one that wasn’t a brand new motor, with around 50 hours of highly enjoyable hovercrafting on it! It features twin carburetors and a bespoke CDi electronic ignition system. Our aim with this engine was to produce an engine to power our new, larger ‘Coastal-Pro’ hovercraft without moving away from the Briggs family of engines and the simplicity and cost effectiveness they offer. We decided that maximum revs must be the same, and as a result, retain reliability as good as the stock engine. These engines are used
So, after some setting up and final adjustments of carbs and timing, the engine was run on the dyno.
Maximum BHP 55bhp at 4600rpm. Now, because we run these engines to a maximum of 4000rpm, the engine can more accurately rated at 50bhp, which is what it produces at that figure. It’s quite possible to run the engine up to 4600rpm for maximum power, but this means further modifications to ensure no loss of the incredible reliability of these commercial specification engines. As an aside, the engine sounds fantastic too and is way smoother than the standard engine, especially at tickover. However, looking at the torque curve more carefully tells the real figure. The Rampage has a peak torque figure 15lb/ft higher than the standard engine… but offers over 80% of this figure from 2100rpm right through to 4000rpm. So, 70lb/ft throughout a substantial part of the rev range is the figure of interest to the hovercraft builder! Fitted in the craft, the throttle response, performance and ability to cruise easily when well loaded is exceptional. And when you want to hurry….it really shifts! Overall, we’re really happy . To the best of our knowledge, no other personal / small hovercraft manufacturer that we know of has actually produced their own, ‘realworld’ power and torque figures for their engines by putting them on a dynamometer. Engine manufacturers figures can often be optimistic and lead us to false conclusions if we’re not careful and just a little skeptical! All credit to Briggs tough, for their exceptional accuracy and honesty! It should also be stressed that www.hovercraft.org.uk
we’ve extensively tested the Rampage engine, installing it into real hovercraft and using it in a real environment. We don’t exceed the safe usable rev limit that we’ve used for six years, and everything that needed to be done to ensure reliability has been done! So what now? We’re currently working on making the engine available for hovercraft builders to install or retro-fit themselves. If you’re looking to buy a personal hovercraft, then this engine is going to be of big interest! We’ve developed the Rampage (in association with OO Racing) for our new Coastal Pro Hovercraft but are making it an ‘off the shelf’ bespoke hovercraft engine for folks who wish to build or restore a hovercraft. We’ll also make it available as a kit with full instructions for those that want to undertake the work themselves.

B&S Rampage 55bhp
It’s particularly suited to small integrated hovercraft, larger ‘plan’ hovercraft such as Sevtecs and Universal Hovercraft or an attractive option for re-engineering older craft. The aim is to have it available by the end of May 2012 – so please drop us a line to register your interest and we’ll keep you posted with pricing and delivery times. We’ll keep you updated via our facebook group, so make sure you ‘like’ us! There’s still another 5bhp in there that we’re not accessing yet, which of course means that a ‘Stage 3’ engine is under develoment which will comprise more internal modifications to allow the revs necessary to access the full 55bhp. We also need to get a ‘small block’ 23bhp onto the dyno and test that in its standard and modified forms. Lots still to do, so watch this space!

Little Scrapper 2 - Pt 3 - The joy of air tools The aim of this project is to build a new craft that could be leant to any member to give them a taste of racing. To that end Jake’s 447 engine and frame have been purloined and the next task is to finish the new Panther hull blagged from Les Bran. Having fitted the buoyancy and joined the upper and lower sections of the hull together last time it’s now time to attach the planing surface to the top deck around the edges. As this hull will be trimmed with aluminium angle (all the better to repel bales, tyres, course markers and trees) I retrieved two 5m lengths of 25mm x 3mm angle from my stock and proceeded to measure up. I always find it useful to glue and rivet the angle to the hull edge, so tidying up the edge to get a smooth clean edge and flange is essential. The front and back of the hull is curved, so to allow the ally angle to conform to the profile of the fibre glass I used an angle grinder with a cutting disc to chop through the lower surface of the ally at 1” intervals to allow the ally to bend around the curves of the hull. I also marked out and drilled the holes that would attach the ally to the hull edge at 6” intervals through the same surfaces. Mock fitting the ally to the hull using G clamps allowed the hull to be drilled from below using the holes in the ally as a guide to ensure an accurate fit. Removing the ally to gain access it’s time to prepare the hull and ally for assembly. Wiping all surfaces down with acetone removed any dust LightHovercraft 12
and grease and provided a good bonding surface for the PU sealant. I use Tiger Seal as it’s just as good and cheaper than Sikaflex and has the added advantage of a flat surface at the nozzle end for my new compressed air driven caulking gun to seal against – an amazingly simple yet effective device which takes all of the stress and pain from using hand actuated sealant applicators. Running a bead of Tiger Seal between the top deck and the flange on the planing surface sticks it together nicely once the rivets are in place, and another bead onto the ally will stick that to the hull. Once the sticky stuff was applied the ally was refitted and clamped in place whilst the large flange rivets were applied. Once again air tools make the job so much easier and the rivets were installed in double quick time with a little sealant under each rivet head to bed the rivet onto the fibreglass and prevent them coming slack later in life. Finally small bridging pieces were made to join across the two ends improving the integrity of the aluminium hoop around the hull. Now the hull is fully together it’s time to finish off the underside. 3” Skirt feed holes were drilled at 6” intervals, with the holes at the front being formed from two 3” holes to increase flow area at the bow. This is done by trimming the edges up with a jigsaw to convert from figure 8 to a neat oval and sanding back any rough edges. The P clips were fitted, first by careful marking
of the position, drilled and riveted on using peel rivets, finally the holes in the rivets are sealed with Tiger Seal to keep the hull water tight. Once back shiny side up it’s time to fit the duct, this involved much measuring, trimming and adjusting to get the cut out in the duct to match the opening in the hull and splitter plate. A jigsaw fitted with an old hacksaw blade is ideal for this and angle grinder with a sanding disc is equally effective at smoothing surfaces and generating more dust. With the duct temporarily glue gunned into place and the disc refitted the engine was offered up in its frame, lining up the centre of the gearbox fan attachment flange with the hole in centre of the disc confirmed the duct height to be correct and a large set square was used to confirm the duct was square to the hull. Before the duct was finally mounted in the hull, the straightners and centre body were made and mock fitted. The straightners being 3 layers thick and single skin, are stiff but have no method of attaching to the duct or centre body, so the correct shaped curve needed to be cut at the correct locations around the centre body, and then in the rear section of the duct. 7 vanes were to be equally spaced and set back from the fan to minimise the noise signature. Marking the angles out on the disk helps ensure correct spacing of the vanes around the cone, and makes for easy transfer of those same angular spaces onto the www.hovercraft.org.uk
duct. With the locations of the axis of the vanes established the correct profile can be drawn onto masking tape applied to the duct inner shin and outer surface of the cone. Drilling a series of small holes in line to enables the jigsaw blade to do its thing and the shapes are cut in both duct, and cone. A similar technique was used to establish the two holes in the splitter plate but due to the geometry the profile required differs considerably, as the vanes go through the flat surface (not curved) and each at different angles. The vanes can now be pushed into the cone and then withdrawn through the holes in the duct and the whole assembly dropped onto the hull before the duct was again aligned with set square, secured with a glue gun, and then glassed into place around all of the points of contact. With the duct now securely fitted, the areas between cone and vane roots, and vane tips and duct have a bead of Tiger Seal applied. This, once smoothed down with a wet finger, forms a nice looking and surprisingly strong joint. Leaving a couple of days for the sealant to dry the vanes were then glassed into place from within the cone and on the outside of the duct. Finally the cone was filled with aerosol foam to increase rigidity and plugged with a circle of polystyrene foam sheet to give a nice neat finish and rounds off the completion of the structure of the hull. Rudders were laid up using yet more material blagged from Les Bran and will be www.hovercraft.org.uk
fitted in the final stages of the build. In the mean time further donations have come rolling in, so I now have a fan hub and blades (thanks Bob), promise of skirt material (cheers Jon) and offer of skirt sewing (you’re a star Louise). So its now just the small matter of fitting the engine, refurbishing the exhaust, finding somewhere to attaché the handle bars and sorting all the twiddly bits that seam to take forever after it all looks to be finished. Once again, thanks to everyone for their offers of bits, money, help and support. Hopefully at this rate it will be up and running and available for use at the first race meeting of the year.

Cullompton Hovergo Day from young enthusiasts about the work being undertaken, and whether they would be driving them before the end of the day? Unfortunately, neither craft made it!
The day was very popular with the general public, with multiple craft spending the day giving rides to well over 100 members of the public, ranging in age from 2 to 65 years old! They were able to experience both cruising and racing craft, and all came back with ear to ear smiles and a greater knowledge of the fun that can be had with hover-crafting!
After many months of planning by Jim Waddel, on the morning of on Saturday 21st April the Cullompton Hover-in was underway! The day, run by Cullompton Community College Technology Club in conjunction with the local youth network and cadet groups, aimed to help raise awareness of the opportunities available for the local youth as well as both the racing and cruising aspects of hovercrafting. A bright sunny morning with clear blue skies (unusual for a hovercraft event!) saw the band of local HCGB members, Technology Club members and parents setting up the site to prevent the usual dog-walkers and other members of the public from casually strolling in front of a flying craft . A larger than expected turnout of a dozen craft started to arrive; a rarely occurring mix of both racing craft and cruisers. This large number of craft helped to make the day run smoothly and ensure a successful day for all involved in the event. There was a large variety in the sizes and type of craft that attended; from large cruising craft such as a TS3 and a Vortex cruising craft to small Venom and Panther racing craft. We were delighted to see familiar faces like Bryan White, Gaz, Rob Cooper, Wayne Hill, John Lawrence, Tom & Mark Robinson, and up and coming ex-junior drivers like James Eddy and Luke Burke, supported by their families and friends. Later in the morning we also saw the arrival LightHovercraft 14
of Keith Oakley, just back from his trip across the channel. Many of those attending had made lengthy journeys to attend, and we are very appreciative of their support. Throughout the day time was spent by various hovercraft owners showing off their craft to the attending youth groups and general public, explaining to them the basic principles of hovercraft construction and how they function. This was greatly helped by having craft in various different stages of assembly from bare hulls through to the final stages of preparation ahead of the new racing season as well as fully functional craft; both James and Luke, who were in the final stages of build/re-build, had regular enquiries
At the end of the day the unanimous opinion was that it had been an overwhelming success, both in bringing the hovercraft community in the South-West together to share their experiences and expertise, as well as bringing the hovercraft experience to the wider community. Thanks must go to all who came and helped on the day, and in particular to Jim for all his hard work in planning and preparing the event, and his unstinting efforts in promoting hovercrafting throughout the day.

The Big Lake Extravaganza – Trials, tribulations and sheep As arranged in a recent Midlands Branch meeting, and published on the forum page, April 7th 2012 was earmarked as the day to trial and prove the proposed National and EHF meeting circuits. On a cold damp Saturday morning a handful of ‘harden’ souls dragged themselves to Holme Pierrepont with a single aim to turn the dream into a reality. As per normal the ‘good old’ English weather had done its best to turn the site into a quagmire in some parts. Keith Rhodes had descended upon the site on the previous day (good Friday) ‘tooled up’ with a JCB to make some necessary modifications to the landscape!!! Alas the 7.5tonne beast (not Keith, the JCB….) proved to us all that talk of a water shortage could be classed as waffle, as the slightly moist conditions didn’t take kindly to the 7.5t hulk rolling over Gods green earth… the less said the better. However, our initial visit last summer did reveal the ground to be concretes’que when dry. So when the sun does decide to show its head in the NG postcodes all should be well! The working party included Daniel Turnbull, Russ Hudson and Jonathon Spedding, whom all gratefully bought various craft along to assist. With Andy Folland and Carl Smith putting the hard yards around the circuit ensuring we meet all the required Health and Safety measures for both the competitors and the spectators. As with all things hovercraft, things got off to the usual and expected slow start!!! After a round of teas and coffees the pace slowly picked up with Jonathon taking various lines across the first land transition, in his electric start 503 (the greatest invention since sliced bread!!!). After around a dozen attempts on various lines the team (consisting of Keith, Daniel, Chris Easterbrook, Andy, Darren and Jonathon, agreed on marker positions both entering and leaving the land, along with buoy positions on the lake. One corner/ transition sorted, another tea break and
re-fuel was now in order!!! Whilst we we’re watching Jonathon complete loop after loop of one corner, Russ decided to fire up the cruiser, and entertain the children with a mini cruise. Watching Thomas 2 and Luke aged 4 Hudson (front and middle) and Adam Turnbull (at the rear) along with Russ at the controls was enough to brighten up any gloomy Saturday morning! See for yourselves – picture courtesy of Lorna Swaine – thanks Lorna!!!! Tea drunk and craft re-fuelled Daniel decided to take the covers off Little Scrapper 2. Built by Dan’s fair hand with assistance from very generous club members donating both time, material and engines, Little Scrapper 2’s time had come…. After 20 minutes of ‘light entertainment’ watching Dan fighting with the Jake Cooper supplied Rotax 447, Scrapper came to life then died, then to life and died again… this continued for a short while much to Dan’s frustration. After some minor ‘tinkering’ it was time to fly!!! Whilst Dan had been fighting with the 447, the team had relocated to the middle land section. A unilateral decision was made to make this the prime spectator position; from this point the general public will be able to see all the circuit. A further key decision was also made, a critical one for all involved, the position of the bar!!!! Whilst this was occurring on the land, Jonathon and Russ took to the lake to undertake some depth tests, as this location is an ex-quarry there were concerns on depths and in the event of a ‘sinking ship’ how easy recovery would be. Against the odds the lake bottomed out at an average 2.4m, thanks must be given to the high tech equipment used in obtaining these depths, I‘m certain the length of rope and brick will come in handy on one of Jonathon’s future business ventures!! During this point the locals joined us on the circuit…. A huge flock of sheep had decided that enough was enough and shifted positions from
World Endurance Race The closing date for entry to the World Endurance Race is the 20th May 2012!!!! You can book your spot on the starting line using the following link on the HCGB web page!!! http://www.ekmpowershop12.com/ ekmps/shops/hovercraft/the-biglake-extravaganza---2-10-june-201272-c.asp Whilst your ‘logged in’ why not book your electric hook up, which will be only £30.00 to cover for the whole event. Also available to purchase are shower tokens for the use of the facilities nearby. the ‘proposed camping area’ to the opposite side of the lake. During this mass transfer of ‘sheepage’, a single lamb was left behind, and was looking lost…. To the rescue came Jonathon, collecting the single lamb up in his arms and made tracks after the flock of moving sheep!!! Our own Doctor Doo-little!!! Whilst Jonathon tracked the local wildlife down, Dan decided to give LS2 her maiden voyage, still with a minor fuel/ carburettor issue Dan took to the lake, followed by myself, in Jonathon’s 503, turning the key and pressing the button on the electric start, Genius!!! Driving in unison we tried around 10-15 different lines, making some minor changes as we went. An agreement was made and the team decided a full lap was in order!!! The final land transition sending us back over the start / finish line proved again as the others before it, perfectly formed by nature with no spadework required! So off we set, over the start line onto the lake and down the long first straight, which goes on and on, but be assured a full field of hovercraft racing ‘hell for leather’ along here will be a spectacle not to be missed! My first full timed lap was around the 2min 20-second mark. So meet the current Fastest Lap Record Holder!!!! Russ and the returning ‘sheep herder’ Jonathon returned and followed us around for a few laps also before we all turned into the land for the last time. All in all a successful mornings work, the circuit nailed, Health and Safety issues addressed, the critical position of the Bar sorted it was time to pack up and leave!! Thanks to all that braved the cold!!!
Letters From Around The World... Six hovercraft were parked in an arc of remembrance for our highly respected colleague with club banner draped over the nose of the largest craft and 2 wreaths and 3 photographs of Des Goss in his multi-coloured Turbo Wedge 225 placed in the focus point as a back drop with family, friends and QSH club members standing in for scores of commemorative photographs.
My son’s first full size craft (unfortunately sand-based) taken on Easter holiday. Had a steering stick.... dashboard with control knobs and a lift fan. Segmented skirt was easy to make with my curved sand shovel turned around backwards and shaved down the side of the sand.
QSH club President Peter Venn gave a send-off tribute to Des Goss at the boat ramp and son Brad Goss gave a formal thank-you response. In attendance: Margaret Goss, Brad Goss and other members of the family: David, Nicki and Emma Bryant; Peter, Elaine, David, AnnaMarie & Thomas Venn, Arthur and Judy Stead, Angus Kerr and Anne & Jeremy Torrance, Kyle Kerr and Doris, Phillip and Kerri Audsley, Bill Toppin, Chris Munck of Kedron, Brett Young of the air cadets, Rita Chaffey and Steven Odgaard. Line up of craft :- Bill Baker 2, (SO) Hoverjet (DV) Viper (AK) Turbo TP6 (PV) Marlin Flying Fish (DV) and Revtech Renegade (AS).

Progress seems to be much slower than many other transportation modes. I am presently building a hovercraft for a customer away north in Nunavut. Very demanding conditions of ice and snow, Everything is to be heavy duty but the overall size is small so hard to accommodate all the requests. May have some pics and something www.hovercraft.org.uk

to write about next month. Just got a phone call right now to supply skirt material for a very old but popular hovercraft here in Canada back in the 70’s and 80’s. It is the STARSHIP model which seems to still keep popping up as there are very few model available in North America. (PS - I hope to change that with a new design!!!) I believe the sport has not grown
An article printed on Sunday 1st April 2012 in the Brisbane Sunday Mail newspaper. Page 33. Hover commute to float Slipper’s boat. By Kathleen Donaghey. James Bond has driven them and Jackie Chan was run over by one. Now independent MP Peter Slipper wants commuters to zip to Brisbane on them. Hovercraft have been floated by the Speaker of the House of Representatives as a solution to transport woes on the Sunshine Coast. The futuristic-looking highspeed craft have proven popular in blockbuster movies and the military, but despite being around for decades, they have not taken hold as a form of large scale passenger transport.
Mr Slipper wants to investigate using hovercraft (like the US navy vessel “LCAC”) On the Pumicestone Passage between Caloundra and Brisbane to take congestion off the Bruce Highway. A parliamentary paper ordered by Mr Slipper and supplied to The Sunday Mail has described the idea as “a novel solution”, but the report warned it could be a “rough ride ahead” for any proposal, given a previous lack of success in Australia. Steven Odgaard (Australia)
very much because of the cost of a new manufactured hovercraft being close to $20.000. A new car cost the same and a hover is so much simpler Ross Wease (Canada)
Nederlandse Hovercraft Club Nieuswbrief 2012 The Dutch Hovercraft Club have kindly sent us a copy of their latest newsletter, firstly we have to thank their Editors Hans Peerenboom and Ben Meijer for kindly forwarding this on to us and letting us use there hard work and endeavours. In defence of Hans and Ben, I will apologise for my translation, as this was self-taught after watching the Austin Powers spoof ‘Goldmember’…. Seriously we have translated this using google translate, which isn’t the “most user friendly and human” of tools, and doesn’t understand both sarcasm and humour!! If google wish to sue me, we’ll see them in court, to prove us wrong! Thanks again Hans and Ben. It is becoming increasingly difficult to get material for the newsletter. That explains why the first edition of 2012 is later than ‘normal’. While we strive to provide a quarterly magazine to give, will this year probably 1x every 4 months if this goes through ... We exist as a club 25 years, we’re like ‘small club’ also are all one bit ‘tired hovercraft’ become? Even for a special edition of the clublad, wholly dedicated to 25 years Hovercraft Club is despite a previous call but very little footage. We find this unfortunate because a “club” that we are still all together? Where is the (club) passion gone? The “drive” for we alldo? It cannot be that the passion for Hovercrafts just yet is propagated LightHovercraft 18
by a few? Okay ... of course, the Dutch legislation allows us as a club and as owner of a hovercraft increasingly difficult, insurers do not participate, Nature Associations are afraid that hovercrafts disturb the natural environment ... but that not really just manifestations of the “unfamiliar with the matter ‘? Tractor pull competitions, Speed boats that sail too hard, motocross riders who destroy our forests, Car (cross) races that exceed noise limits and so on ... those are much “worse”? But ... that kind of vehicles we know, and so we tolerate that! Come on people! ... We let us not just in a corner button? We get by Housing and all insurers do not sideline? Come on! Be proud! Tone again that you are an active member of the Dutch Hovercraft Club! Only in this way we get the next 25 years ... that you want as well? Let his all the club back on the map! We are a small club, but a to be proud of! We go for it ... you guys too? Of course! ... Because the technology behind the hovercraft is way too pretty for posterity ‘ to lose ‘... Let everyone know! ‘I’ am a member NHC! And a hovercraft .... “that’s my passion and my life!” ... In any case there is another magazine ready for you, again ... a lot reading ... The editors, Hans Meijer & Ben Peerenboom Christy Hovercraft. Christy Hovercraft is a Russian manufacturer of various hovercraft models such as Christy 6132 and 6143 both of which accommodate up to 6 people. In addition, Christy Hovercraft distributor hovercraft
of the U.S. company Neoteric Hovercraft, Inc.. that mostly 4 to 6 person hovercraft and produces the Australian company AirLift HOVERCRAFT that the segment is larger hovercraft and mainly produces 6 to 25 seater hovercraft. In short, all of Christy’s Hovercraft rounder when it comes to delivering Hovercrafts up to 25 people. The 6143 Christy is a very interesting and promising new model and meets the latest technology. Once this model released for the “international market” for hovercrafts, this model eyes high throw. Unfortunately it is not there yet, because this model only still be offered locally in Russia and the fact that there simply was not enough Christy 6143 models to also be able to export and that also remains equally. For the local domestic market, there are currently enough applications be dealt with first, but 1 thing sure ... when the opportunity presents itself to the distribution to increase, will Christy Hovercraft this occasion with to seize market share outside Russia Available for all models Christy Hove craft. What the current models, only the 6143 Christy is currently on the assembly line produced. The other model, the 6132 Christy is only produced on special request, such Hovercraft as a customer with more propulsion power and / or Payload need. Each application for a Christy 6132 is, therefore, a separate “contemplated”, depending on by a customer supplied specifications. In the first quarter of 2012 think Christy’s Hovercraft to the extent that the first orders of Foreign customers outside of Russia has, www.hovercraft.org.uk
in treatment can be taken. The ‘Ex Works’ price of a Christy 6143 will probably be around 69,500 Euros come to lie.
