The "pods" were bought at an auction for a dollar, the extentions are 2" aluminum tubing 10' long, it's held together by ratchet straps, and the deck just sits on top, in the pic, you can see ripples, they are from my Daughter Jess, ans she tries to rock the boat while I shoot to throw me off, didn't work, as I still hit my target,lol,lol the boat is very stable, but much harder to paddle, hence the trolling motor. and one time this summer we had some people over and I put my lazy boy on it for kicks and went fishing, should have seen their faces,lol,lol. Priceless!
