Thanks for the ideas. I like the zip ties with triggers, so now I just have to find some. The sheet metal screws were also a nice idea. I like the idea of easy repairs, although pvc isn't too hard to deal with.

The boat is dark green, so background shouldn't be a problem, and there will be two layers of camo netting, so it would be pretty hard to see through.

Thanks for the ideas. Once I get this thing done, I'll have my father-in-law snap a picture of it with his digital and post it.
