SD - What size and model of Achilles do you have? I am looking at buying one for next year, and may buy now with the sales, and good $ exchange.
I am looking at the 9'6" or 10'4" in either the wood floor, or the inflatable floor. I will be towing most of the time, but will store in / on the boat for some trips. Weight difference is about 30 lbs more for the aluminum roll-up.
re: moters, looking at a honda 2hp (light and internal tank, just to get out to the boat / mooring) or 5hp (heavy but fun, able to cruise around a little faster)
