Formula 31 Cruiser 2005 vs Formula 34 Performance Cruiser 2008 — Same Brand, Different Boat

The Formula 31 Cruiser 2005 vs Formula 34 Performance Cruiser 2008 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 31 Cruiser 2005 at 33,0 ft versus Formula 34 Performance Cruiser 2008 at 34,0 ft. Weight tells a clearer story for trailering families: the Formula 34 Performance Cruiser 2008 tips the scales at 1 691 lbs — 1 550 lbs less than the Formula 31 Cruiser 2005 at 141 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.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Formula 31 Cruiser 2005 and Formula 34 Performance Cruiser 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Formula 31 Cruiser 2005 vs Formula 34 Performance Cruiser 2008 — Common Questions

Which is the larger boat — the Formula 31 Cruiser 2005 or the Formula 34 Performance Cruiser 2008?
The Formula 34 Performance Cruiser 2008 is the longer of the two at 34,0 feet overall. The Formula 31 Cruiser 2005 comes in at 33,0 feet, making it roughly 1,0 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 34 Performance Cruiser 2008?
For trailering, the Formula 31 Cruiser 2005 has the edge at 141 lbs dry weight versus 1 691 lbs for the Formula 34 Performance Cruiser 2008. 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 34 Performance Cruiser 2008 is certified for 10. 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 34 Performance Cruiser 2008 measures 138" wide, compared to 132" for the Formula 31 Cruiser 2005. 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 2005 or the Formula 34 Performance Cruiser 2008?
The Formula 34 Performance Cruiser 2008 has the bigger tank at 206 gallons, versus 18 gallons on the Formula 31 Cruiser 2005. That 188-gallon difference translates to roughly 564–940 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Formula 31 Cruiser 2005 and Formula 34 Performance Cruiser 2008 from the same manufacturer?
Yes — both the Formula 31 Cruiser 2005 and the Formula 34 Performance Cruiser 2008 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.
