Detailed Evaluation & Buyer Recommendation
Formula 31 Cruiser 2006 vs Formula 350 Sun Sport 2008 — Same Brand, Different Boat
The Formula 31 Cruiser 2006 vs Formula 350 Sun Sport 2008 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.
On paper these two are close siblings in the size department — Formula 31 Cruiser 2006 at 33,0 ft versus Formula 350 Sun Sport 2008 at 35,0 ft. Weight tells a clearer story for trailering families: the Formula 350 Sun Sport 2008 tips the scales at 1 295 lbs — 1 154 lbs less than the Formula 31 Cruiser 2006 at 141 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 are rated for 10 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 Formula 31 Cruiser 2006 and Formula 350 Sun Sport 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
