The Bennington 1650 FSi 2006 vs Bennington 2550 RSFB 2017 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
The power gap is worth calling out. Rated to 350 hp, the Bennington 2550 RSFB 2017 has a 300-hp advantage over the Bennington 1650 FSi 2006's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bennington 2550 RSFB 2017 carries 48 gallons versus 31 gallons in the Bennington 1650 FSi 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 7 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.
The Bennington 1650 FSi 2006 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Bennington 2550 RSFB 2017 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Bennington 2550 RSFB 2017 at 25,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Bennington 1650 FSi 2006 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.
