We do keep them in the garage.
We have a yearly pass at our local county park on the Sacramento river here in Rio Vista. They have a nice boat ramp and we just back them down and slide them off into the water. We float/walk them over to the beach and extend the amas and off we go. Last month we took them to Bodega Bay. There we slid them off and attached the beach wheel cart and rolled them out onto the beach.
It's the light weight and ease of loading/unloading and ease of sailing that is really the fame of these boats. My wife never really enjoyed all the cats we have had because of the work involved in rigging and launching them. The AI's have made it possible for my wife to get as much enjoyment (maybe more) from sailing as myself. That is something I've always wanted (Thank you Hobie).
Sorry if I strayed from the point of this thread.
The advantage of the Rack-n-Roll is that if you have limited storage space you can pull the boats off and fold things up, hang it on or lean it against the wall.
That's just too much work for me. The Hobie trailer makes life easy but it does take up half my garage. When I want to get to my tool box or the drill press I have to open the big door and pull it out five or six feet. Having fussed with small boat trailers all my life I have learned the value of a cheap folding tonge wheel and a lift handle.
