Formula 31 Cruiser 2005 vs Formula 400 Super Sport 2009 — Same Brand, Different Boat

The Formula 31 Cruiser 2005 vs Formula 400 Super 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 400 Super Sport 2009 measures 41,0 feet overall (2009), giving it roughly 8,0 additional feet of deck space compared to the Formula 31 Cruiser 2005 at 33,0 feet (2005). At 141 lbs and 181 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 400 Super Sport 2009 is rated for 12 passengers, while the Formula 31 Cruiser 2005 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 400 Super Sport 2009 could be the deciding factor.

Bottom line: Choose the Formula 400 Super Sport 2009 if your priority is putting more people on the water — it handles 12 passengers and at 41,0 ft it has the deck room to back that rating up comfortably. The Formula 31 Cruiser 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Formula 31 Cruiser 2005 vs Formula 400 Super Sport 2009 — Common Questions

Which is the larger boat — the Formula 31 Cruiser 2005 or the Formula 400 Super Sport 2009?
The Formula 400 Super Sport 2009 is the longer of the two at 41,0 feet overall. The Formula 31 Cruiser 2005 comes in at 33,0 feet, making it roughly 8,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Formula 31 Cruiser 2005 or the Formula 400 Super Sport 2009?
For trailering, the Formula 31 Cruiser 2005 has the edge at 141 lbs dry weight versus 181 lbs for the Formula 400 Super Sport 2009. 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 31 Cruiser 2005 is Coast Guard rated for 10 passengers, while the Formula 400 Super Sport 2009 is certified for 12. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Formula 31 Cruiser 2005 and Formula 400 Super Sport 2009 share an 11 ft. 0 in. (3.35 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Formula 31 Cruiser 2005 or the Formula 400 Super Sport 2009?
The Formula 400 Super Sport 2009 has the bigger tank at 25 gallons, versus 18 gallons on the Formula 31 Cruiser 2005. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Formula 31 Cruiser 2005 and Formula 400 Super Sport 2009 from the same manufacturer?
Yes — both the Formula 31 Cruiser 2005 and the Formula 400 Super Sport 2009 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.
