Matching a modified vee Fisher 1648 SS All Welded Jon 2007 against a pontoon Fisher 18 Spirit 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Fisher 1648 SS All Welded Jon 2007 at 16,0 ft versus Fisher 18 Spirit 2009 at 19,0 ft. Weight tells a clearer story for trailering families: the Fisher 18 Spirit 2009 tips the scales at 1 174 lbs — 1 118 lbs less than the Fisher 1648 SS All Welded Jon 2007 at 56 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
Both boats share a closely matched power ceiling — 40 hp for the Fisher 1648 SS All Welded Jon 2007 and 50 hp for the Fisher 18 Spirit 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
Both boats are rated for 5 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 Fisher 18 Spirit 2009 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Fisher 1648 SS All Welded Jon 2007 at 16,0 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.
