5 Weathertight Integrity This section is intended to outline standards to be achieved for weathertight integrity. As far as is practicable, the standards of the 1966 ICll are to be adhered to. However, due consideration may be given to arrangements that provide an equivalent level of safety in respect of the risks of down flooding and green sea loading. Virtual Freeboard Deck For the purposes of this section only, where actual freeboard to the weather deck exceeds that required by ICll 66 by at least one standard superstructure height, openings on that deck, abaft of the forward quarter, may be assumed to be in position 2. This is to be taken, unless otherwise stated, as defined in ICll 66. For yachts up to 75m load line length, a standard superstructure height is to be taken as 1.8m. Superstructure heights for yachts of intermediate lengths should be obtained by interpolation. 5.1 Hatchways and Skylight Hatches 5.1.1 GENERAL REQUIREMENTS 5.1.1.1
All openings leading to spaces below the weather deck not capable of being closed weathertight must be enclosed within either an enclosed superstructure or a weathertight deckhouse of adequate strength meeting with the requirements of the load Line Assigning Authority. 5.1.1.2
All exposed hatchways which give access from position 1 and position 2 are to be of substantial weathertight construction and provided with efficient means of closure. Weathertight hatch covers should be permanently attached to the yacht and provided with adequate arrangements for securing the hatch closed. 5.1.1.3
Hatches which are designated for escape purposes should be provided with covers which are to be openable from either side and in the direction of escape they are to be openable without a key. All handles on the inside are to be non-removable.
