The Rules for the Classification of Trimarans apply to vessels with three hulls of displacement form, a main centre hull stabilised by two much smaller side hulls. The Trimaran Rules may also apply to vessels with three hulls of planing or semi-planing form or to vessels with five hulls, described as pentamarans. In these cases, special arrangement must be made with LR.


These Rules are to be applied in conjunction with, as appropriate to the vessel type:
