I can't find DWSC constitution on-line, but a quick google for sailing club constitutions indicates that:

- Yarmouth sailing club requires 2/3 of the *members* to suspend of exclude someone
- Montrose sailing club has a lengthy process that could be triggered only if "the behaviour of any member, in any respect is considered to be contrary to The Constitution, the good name of The Club, the fabric and the assets of The Club or the safety of themselves or others". Fairly specific.
- Norfolk consider you no longer a member if you don't pay or in case of "resignation, bankruptcy or death."
- Southern sailing club: no clause.

This clause doesn't seems that common...
