Both the Avalon 18 ft. A Fish - Fish N Fun RE 2012 and the Avalon Windjammer - 18 Foot 2008 are pontoon designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
