DIN EN ISO 11812:2018-03

This document specifies requirements for recesses and cockpits in terms of watertightness, draining time, and sills in way of cockpit companionway doors or hatches, for small craft up to 24 m length of hull. It is aimed at minimizing the ingress of water into the interior of the craft from a recess or cockpit. It does not set requirements for the size and the shape of a recess or cockpit, nor when or where it shall be used. It only considers draining by gravity, and not by pumping or other methods. This standard does not guarantee that the water contained in a watertight or quick draining recess or cockpit will not harm stability and floatability, which are covered by ISO 12217.
