Small craft - Watertight or quick-draining recesses and cockpits (ISO 11812:2020)

This document specifies the watertightness, draining time and coaming height requirements for watertight and fast-draining recesses and cockpits in small vessels with a loading line length of up to 24 m (see reference [1]). Recesses located on elevated parts of the vessel are covered by this document. This document does not specify requirements for the size, shape and location of recesses or cockpits. It only considers drainage by gravity and not by pumping or other methods. It only considers the normal operation of the watercraft, but unresolved problems with recessions in unmanned watercraft are outside the scope. This document does not ensure that water in a watertight or quick-draining cockpit or cockpit will not affect the stability and buoyancy of the vessel. This is covered by ISO 12217:2015 (all parts).
