Just a thought, but if someone has an inflatable dinghy you could use a paddle or pole to push yourself out with a heavy rope and second rope, cut the max out (leaning on the tube, don't leave it) attach heavy rope/cable and get pulled in by the smaller rope. Now winch the max in. Just a thought, but the dingy won't go through, it'll spread the load out a lot, and EVEN if it did, you'd be floating with a rope to get pulled right back in. Personally, I think this is how I'd attack it. I'd be confident only since I'm in something that floats better than an AATV, and I have assistance and a tow rope handy already. Just be sure the saw is covered so the teeth don't meet the tube
