Detailed Evaluation & Buyer Recommendation
Formula 31 Cruiser 2006 vs Formula 310 Sun Sport 2010 — Same Brand, Different Boat
The Formula 31 Cruiser 2006 vs Formula 310 Sun Sport 2010 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 310 Sun Sport 2010 at 31,0 ft. Weight tells a clearer story for trailering families: the Formula 310 Sun Sport 2010 tips the scales at 975 lbs — 834 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.
For family outings this is probably the sharpest distinction between the two. The Formula 31 Cruiser 2006 is rated for 10 passengers, while the Formula 310 Sun Sport 2010 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 31 Cruiser 2006 could be the deciding factor.
Bottom line: Choose the Formula 31 Cruiser 2006 if your priority is putting more people on the water — it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Formula 310 Sun Sport 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
