Detailed Evaluation & Buyer Recommendation
Formula 27 Cruiser 2005 vs Formula 310 Sun Sport 2009 — Same Brand, Different Boat
The Formula 27 Cruiser 2005 vs Formula 310 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.
On paper these two are close siblings in the size department — Formula 27 Cruiser 2005 at 29,0 ft versus Formula 310 Sun Sport 2009 at 31,0 ft. Weight tells a clearer story for trailering families: the Formula 310 Sun Sport 2009 tips the scales at 975 lbs — 880 lbs less than the Formula 27 Cruiser 2005 at 95 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 310 Sun Sport 2009 is rated for 9 passengers, while the Formula 27 Cruiser 2005 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 310 Sun Sport 2009 could be the deciding factor.
Bottom line: Choose the Formula 310 Sun Sport 2009 if your priority is putting more people on the water — it handles 9 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The Formula 27 Cruiser 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
