ISO 11812:2001 PDF

Scope: This standard specifies the requirements for stern compartments and recesses specifically designated as "watertight" or "rapidly draining" on small boats with a hull length not exceeding 24 m. This standard neither sets requirements for the size and shape of stern tanks or recesses nor prescribes when or where they should be used. Consider draining only by gravity, not by pumps or other methods. Note 1: The term "quickly draining stern tank" has been selected to distinguish it from the commonly understood "self-draining stern tank", in which water can be discharged overboard under certain conditions, but the water discharge speed and speed are not specified. The height of the bottom or sill, etc. Feng 2: An example of a single-plane stern tank bottom is given in Appendix A.
