Sniper,
I bet you're not looking for a bullet proof set up like on the boat shown on this post. It's a nice set up, but over kill IMHO. Any good canvas shop can make you what you want. I'm guessin' the cost would be under $2000. I have an Albin 27 with camping canvas. If I can post a picture I will. I have this boat for sale, otherwise I'd replace the canvas, and have the back come straight down , rather then the 45ish* it drops now. My cost here in NJ was $1500 to replace the canvas, new bows too. It will require a bunch of snaps be installed. Some owners don't care for the holes.
