Formula 290 Sun Sport 2009 vs Formula 310 Sun Sport 2007 — Same Brand, Different Boat

The Formula 290 Sun Sport 2009 vs Formula 310 Sun Sport 2007 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 290 Sun Sport 2009 at 29,0 ft versus Formula 310 Sun Sport 2007 at 31,0 ft. At 895 lbs and 975 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

For family outings this is probably the sharpest distinction between the two. The Formula 310 Sun Sport 2007 is rated for 9 passengers, while the Formula 290 Sun Sport 2009 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 2007 could be the deciding factor.

Bottom line: Choose the Formula 310 Sun Sport 2007 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 290 Sun Sport 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Formula 290 Sun Sport 2009 vs Formula 310 Sun Sport 2007 — Common Questions

Which is the larger boat — the Formula 290 Sun Sport 2009 or the Formula 310 Sun Sport 2007?
The Formula 310 Sun Sport 2007 is the longer of the two at 31,0 feet overall. The Formula 290 Sun Sport 2009 comes in at 29,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Formula 290 Sun Sport 2009 or the Formula 310 Sun Sport 2007?
For trailering, the Formula 290 Sun Sport 2009 has the edge at 895 lbs dry weight versus 975 lbs for the Formula 310 Sun Sport 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Formula 290 Sun Sport 2009 is Coast Guard rated for 8 passengers, while the Formula 310 Sun Sport 2007 is certified for 9. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Formula 310 Sun Sport 2007 measures 114" wide, compared to 108" for the Formula 290 Sun Sport 2009. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Formula 290 Sun Sport 2009 and Formula 310 Sun Sport 2007?
Both boats carry similar fuel loads — 11 gallons and 13 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Formula 290 Sun Sport 2009 and Formula 310 Sun Sport 2007 from the same manufacturer?
Yes — both the Formula 290 Sun Sport 2009 and the Formula 310 Sun Sport 2007 are built by Formula. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
