6 Water Freeing Arrangements This section provides for consideration of the risks of green water being shipped aboard and the resulting consequences with respect to the yacht's stability and safety of personnel on deck. 6.1 General
The standards for water freeing arrangements should comply with ICLL as far as it is reasonable and practicable to do so. In any case the intention should be to achieve a standard of safety which is at least equivalent to the standard of ICLL. Additionally, where a well is created on each side of the yacht between a superstructure or deckhouse, and the bulwark in way of that superstructure or deck house, the following formula may be used to determine the required freeing port areas on each side of the yacht for the well concerned:
FP
REQ
= 0.28Ă—AwB
Where: FP = Freeing port area required A = Area of well in way of superstructure or deckhouse B = Full beam at deck REQ
w
On sailing yachts, where the solid bulwark height does not exceed 150mm, specific freeing ports, as defined above, are not required.
