Detailed Evaluation & Buyer Recommendation
Formula 31 Performance Cruiser 2007 vs Formula 350 Sun Sport 2009 — Same Brand, Different Boat
The Formula 31 Performance Cruiser 2007 vs Formula 350 Sun Sport 2009 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.
Size is the most obvious dividing line here. The Formula 350 Sun Sport 2009 measures 35,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Formula 31 Performance Cruiser 2007 at 31,0 feet (2007). Weight tells a clearer story for trailering families: the Formula 350 Sun Sport 2009 tips the scales at 1 347 lbs — 1 206 lbs less than the Formula 31 Performance Cruiser 2007 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 350 Sun Sport 2009 is rated for 10 passengers, while the Formula 31 Performance Cruiser 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 350 Sun Sport 2009 could be the deciding factor.
Bottom line: Choose the Formula 350 Sun Sport 2009 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Formula 31 Performance Cruiser 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
