When two boats share the same hull type — in this case both the Gator Trax 20 x 62 2009 and the Gator Trax Gator Hide 18 x 62 (4 man) 2008 are flat designs with aluminum construction — 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?
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Gator Trax Gator Hide 18 x 62 (4 man) 2008 at 18,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Gator Trax 20 x 62 2009 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
