ISO/TC 188/WG 3 - Cockpits: deck fittings and rigging parts

This document specifies watertightness, draining time and sill heights requirements for watertight and quick-draining recesses and cockpits in small craft of up to 24 m load line length (see Reference [1]). Recesses located in elevated parts of the craft are covered by this document. This document does not specify requirements for the size, the shape and the location of recesses or cockpits. It only considers draining by gravity, and not by pumping or other methods. It only considers normal operation of the craft, but unattended craft recess issues are out of scope. This document does not guarantee that the water contained in a watertight or quick-draining recess or cockpit will not affect the stability and buoyancy of the craft, which are covered by ISO 12217 (all parts):2015.

ISO 15085:2003 specifies the design as well as the construction and strength requirements for safety devices and arrangements intended to minimize the risk of falling overboard, and requirements to facilitate reboarding. It describes means which can be used individually or combined to achieve these objectives, and applies to small craft of up to 24 m length of hull. ISO 15085:2003 is not applicable to the following boat types: aquatic toys; canoes, kayaks, or other boats with a beam less than 1,1 m; personal watercraft, covered by ISO 13590; inflatable boats with a hull length of less than 8 m, covered by ISO 6185.

This International Standard specifies requirements for cockpits and recesses to be designated either as "watertight" or as "quick-draining" on small craft of hull length up to 24 m. It does not set requirements for the size and shape of a cockpit or recess, nor when or where it shall be used. It only considers draining by gravity, and not by pumping or other methods. NOTE 1 The term "quick-draining cockpit" has been chosen to differentiate from the common understanding of "self-draining cockpit" where water may be drained overboard in certain conditions, but without specified draining speed, height of bottom or sill, etc. NOTE 2 Examples of single-plane cockpit bottoms are given in informative annex A.

Defines the main dimensions of the concerning parts of rigging screws for stainless steel wire rope, to ensure the compatibility, assembly and interchangeability of the various parts of standing rigging and attachments of yachts.

Specifies the dimensions for T- or C-shaped tracks for yachts to ensure their interchangeability.

Specifies the main characteristics for waste water pump-out fittings on board yachts.
