There are several levels of membership:
- Membership of BISMA
- ISMA fee (Boats are required to be registered with ISMA to be eligible to race in International events including UK events open to International participants – each registration contributes one vote to the block vote of the BISMA representative during ISMA voting. Boats under restoration or not in class need not be registered with ISMA)
- Associate Membership for those interested in the class or with boats not in class or under restoration
- Friends of the class – free – to receive occasional newsletters, etc – see here
Full details are explained on the membership application form, which can be downloaded here, including arrangements for shared ownership and multiple boats.
