5.2.1 Doorways located above the weather deck

5.2.1.1 External doors in deckhouses and superstructures that give access to spaces below the weather deck, are to be weathertight and door openings should have coaming heights of at least:

Location	Unrestricted Yachts	Short Range Yachts
A	600mm	300mm
B	300mm	150mm
C	150mm	75mm

Location A	The door is in the forward quarter length of the vessel and is used when the vessel is at sea.
Location B	The door is in an exposed forward facing location aft of the forward quarter length.
Location C	The door is in a protected location aft of the forward quarter length, or an unprotected door on the first tier deck above the weather deck.

5.2.1.2 Weathertight doors should be arranged to open outwards and when located in a house side, be hinged at the forward edge. Alternative closing arrangements will be considered providing it can be demonstrated that the efficiency of the closing arrangements and their ability to prevent the ingress of water will not impair the safety of the vessel.

5.2.1.3 An access door leading directly to the engine room from the weather deck should be fitted with a coaming of height of at least;

Location	Unrestricted Yachts	Short Range Yachts
Position 1	600mm	450mm
Position 2	380mm	200mm

5.2.1.4 Coaming height, construction and securing standards for weathertight doors which are provided for use only when the vessel is in port or at anchor in calm sheltered waters and are locked closed when the vessel is at sea, may be considered individually.
