Main advantages of our design Design built on experience Our vessel design is a result of research and tests, performed in close cooperation with Icelandic fishermen for the last decades. Interaction between hull and propeller are designed to give maximum bollard pull. Fuel economy features Keel design ensures good flow to propeller – thus better cruse stability when trawling and better fuel economy! Highly dependable electrical winches with sophisticated automatic control system – thus a better fuel economy! Electric power quality correction technology reduces interferences, distortions and surges – thus a better fuel economy! Designed by:
