Formula 31 Cruiser 2006 vs Formula 37 Cruiser 2010: Same Brand, Different Boat

The Formula 31 Cruiser 2006 vs Formula 37 Cruiser 2010 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 37 Cruiser 2010 measures 37,0 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Formula 31 Cruiser 2006 at 33,0 feet (2006). Weight tells a clearer story for trailering families: the Formula 37 Cruiser 2010 tips the scales at 18 900 lbs - 4 800 lbs less than the Formula 31 Cruiser 2006 at 14 100 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 37 Cruiser 2010 is rated for 11 passengers, while the Formula 31 Cruiser 2006 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 37 Cruiser 2010 could be the deciding factor.

Bottom line: Choose the Formula 37 Cruiser 2010 if your priority is putting more people on the water - it handles 11 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Formula 31 Cruiser 2006 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 2006 vs Formula 37 Cruiser 2010 - Common Questions

Which is the larger boat - the Formula 31 Cruiser 2006 or the Formula 37 Cruiser 2010?
The Formula 37 Cruiser 2010 is the longer of the two at 37,0 feet overall. The Formula 31 Cruiser 2006 comes in at 33,0 feet, making it roughly 4,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Formula 31 Cruiser 2006 or the Formula 37 Cruiser 2010?
For trailering, the Formula 31 Cruiser 2006 has the edge at 14 100 lbs dry weight versus 18 900 lbs for the Formula 37 Cruiser 2010. 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 2006 is Coast Guard rated for 10 passengers, while the Formula 37 Cruiser 2010 is certified for 11. 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 37 Cruiser 2010 measures 144" wide, compared to 132" for the Formula 31 Cruiser 2006. 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.
Which boat has the larger fuel tank - the Formula 31 Cruiser 2006 or the Formula 37 Cruiser 2010?
The Formula 37 Cruiser 2010 has the bigger tank at 236 gallons, versus 180 gallons on the Formula 31 Cruiser 2006. That 56-gallon difference translates to roughly 168–280 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Formula 31 Cruiser 2006 and Formula 37 Cruiser 2010 from the same manufacturer?
Yes - both the Formula 31 Cruiser 2006 and the Formula 37 Cruiser 2010 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.
