Hi Mark,
You are probably right about the ratio of work via good intentions vs. outcome. Maybe boat shows are not the best use of our dwindling free time and resources.
We did try the mast-up storage thing, but, to date, have not had any success through the state parks. As far as exisiting yacht clubs go, there are a few that might have facilities for mast-up storage further West on the Island, but none near me. Those clubs are very pricey with long waiting lists besides. Even my own yacht club ousted me when we lost most of our beach last winter due to many Nor-easter's. We had to make room for the youth program sunfish, which is the club's primary responsibility (and I am the rear commodore!).
But you are correct - Yacht club usage (or building) is the way to go. Let me think about what can be done in my area and I'll get back to you...
