Matching a modified vee Fisher 1648 T Blind Duck Edition 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 T Blind Duck Edition 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 — 1 120 lbs less than the Fisher 1648 T Blind Duck Edition 2007 at 54 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 — 50 hp for the Fisher 1648 T Blind Duck Edition 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.
For family outings this is probably the sharpest distinction between the two. The Fisher 18 Spirit 2009 is rated for 5 passengers, while the Fisher 1648 T Blind Duck Edition 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fisher 18 Spirit 2009 could be the deciding factor.
Bottom line: Choose the Fisher 18 Spirit 2009 if your priority is putting more people on the water — it handles 5 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Fisher 1648 T Blind Duck Edition 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
