Lasting or Light Weight
If you're going to lift the inflatable digny and launch it every time you go somewhere a heavy inflatable will be a lot of work. Also, if you stay near the US where you can buy another one when there is a major problem then how well it lasts isn't as important. In this case I'd recommend non-Hypalon because of the Hypalons heavier weight. Don't expect the non-Hypalon to last forever, though. Before buying our Avon I talked to many long-time boaters about what to get and invariably the ones that had an Avon started with something else and got tired of problems. Many of these boaters were cruisers that went from Puget Sound to Mexico and the South Pacific. At the time they recommended Hypalon and Avon in particular. Consequently, I bought an Avon too and it's 11 years old now, and holding up fine. I stow it on the coach roof, folded up, on our 35 footer. It's the 3.15 roll-up and weighs in at around 115 lbs, dry. I use the preventer off the main haylyard to launch and retrieve it but it's still heavy. I also use an 8hp outboard and it really scoots with one person but loaded with two people it's marginal to get on a plane.For putzin around I'd go with a small, lightweight 10-something footer and a small outboard. Otherwise, the 3.15 with a 9.9 would be a blast!Good luck in your decision. It's only money.
