positions when racing.
Crew number and crew classifi cation
Except for the special case of boats holding either short-handed or ‘one-design’ certifi cates (which must
comply with their class rules in respect of crew), unless a notice of race specifi cally includes crew number
limitations or requires boats to hold an endorsed certifi cate, there are no crew number or weight limitations
when racing under IRC. Similarly, there are no restrictions on crew classifi cation, again unless invoked by
notice of race. For these issues therefore, boats need to refer to notices of race for compliance issues.
IRC Crew Number is not variable by a boat and has no effect on TCC.
