Detailed Evaluation & Buyer Recommendation
Formula 310 FX5 2013 vs Formula 350 Sun Sport 2008: Same Brand, Different Boat
The Formula 310 FX5 2013 is a deep-V design and the Formula 350 Sun Sport 2008 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Formula 350 Sun Sport 2008 measures 35,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Formula 310 FX5 2013 at 31,0 feet (2013). Weight tells a clearer story for trailering families: the Formula 350 Sun Sport 2008 tips the scales at 12 950 lbs - 3 200 lbs less than the Formula 310 FX5 2013 at 9 750 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 2008 is rated for 10 passengers, while the Formula 310 FX5 2013 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 2008 could be the deciding factor.
Bottom line: Choose the Formula 350 Sun Sport 2008 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 310 FX5 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
