My club is like that,
Tradewinds Sailing Club - San Francisco Sailing Lessons |Bay Area Sailing | Sailing school | Women sailing | Sailing lessons | Sailing classes | Sailing Instruction | Sailing club | ASA | Sailing vacations | Sailing Lessons, San Francisco, sailboat r , well I should say the one I belong to, sans the racing, although there are many opportunities. I pay a flat fee per month, much less than slip fees and can take out the boats as much as I want depending on which fleet size I am checked out on.
I believe it is the only club in the US structured like this. The ASA classes are pretty inexpensive also, and I have absolutely no complaints.
