I was thinking about getting a boat similar to yours. My friend has a nice one with the fiberglass bottom and the inflated pontoons. Where do you take yours? Does it ever see salt water?
My vision of my dive setup, is this. Since I will be buying a Wrangler, it wont have much safe storage. A utility/cargo trailer, nothing obnoxious, 6x8 or something. Set up inside for diving. Rack for tanks, hangers for suits, spot for the rinse tub for the gear. A bench to change on. Of course, all would be able to be removed, if I needed to use the trailer for something else. It would serve a changing and storage. A place to keep my dog while diving. If I had a boat like yours, it could be delfated and stored in the trailer. With a brace to hold the motor.
Of course, at the moment, it is all fantasy.
