I agree Rusted On. Freo should keep the membership component, and for the seat rental component give members the option to either be refunded, receive a credit next season, or donate the money.
For those who 'donate' their seat rental money, make them a Harbour Master or something. It seems like the primary benefit of being a Harbour Master is to be able to lord it over everyone at the drop of a hat, so it seems like it would be a win for everyone (except for those who now have to put up with four times as many Harbour Masters).
Regards,
Morgan (future insufferable Harbour Master).
