Re: Co-op climate controlled boat storage/workshop!
The challenge in this idea, and why you may see it with cars and not boats is:
1) As stated above, security. It's rough to lock a boat storage area, while you can lock individual garage's.
2) In some cases, you can subdivide a large space into small 'bays' or garage's. Cars are not THAT big, as compared to boats. Most cars are within relatively the same size range...unlike boats. You can't have all 40 foot bays, and you can't have all 25 ft. bays.
3) Because boats are very large in some cases, and because they are oddly shaped, you are limited in how many you can fit in a space. Rack storage addresses some of this, however even in rack storage you may be limited to length, beam, and weight. If you want to actually WORK in the space, rack storage because a limiting issue. (arranging for time on the work floor with the other occupants.
So, if you have a building in which all the boats are stored on the floor, you are going to be severly limited in the number of boats, or total boat feet you can get into the space.
Cost of building, insurance, taxes, operating expenses divided by number of boat feet capacity = cost
This might work with cars or small co-op shared work space, such as with artists. It will be a very, very pricey $/ft for this type of a venture, which makes it a tough sell. Suddenly shrink wrap and keeping an eye on the weather forcast starts to look like an acceptible alternative.
