We found a number of different options, from co-ops to clubs to private. We chose a private arrangement. The owner of the boat owns it and we and one other person pay a yearly fee for use. Technically we each get 10 days a month but really we all just let each other know when we plan to use it and so far its been no problem. The owner pays all the expenses for moorage, maintenance
, etc... We like the simplicity of this arrangement and the cost was comparable to 2 shares in the co-op, a little less that the cost of the club. Downside is the boat is not what we would choose. It's an old Catalina
27 with hank on sails
and no equipment
but the marina is close to where we live and for learning
and just sailing around the bay it's great. We pay $2k for the year which is $170 a month. We'll probably not sail about 4-5 months though just because its cold and wet so that brings the cost up. But the co-op and club required a year commitment too so we'd be paying for months were not likely to use regardless.
