Thanks Chem, your enclosure was the inspiration for this one. It has rained the past several days and no water in the boat, so that was one goal accomplished. I will probably run most of the year with the back off, and in the heat of summer with the side panels down. There are 7 panels, so about a million zippers, including the ones to attach to the tubing frame. Top, 2 sides with windows, front clear panel over windshield, back panel with window, and 2 rear corner panels between the back and sides, where you would normally enter the boat. (or put a rod out).
Peter, the enclosure is a custom, as there is no ready made setup for a boat like a Chief. The best you can do is what I did. Find a local boat canvas person, take some pictures in of what you would like to do, and get an estimate. Repeat several times, weigh references, and then decide what you want to do. And it cost me way too much......expect the estimates to be too low. I know Chem started with a bimnini and added on, and after getting this one done as a custom, I think you would save money doing that rather than have the canvas person make up a frame and fittings. It might not fit quite as well, but that is a lot of labor hours.
