Formula 31 Cruiser 2011 vs Formula 34 Cruiser 2009 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Formula 31 Cruiser 2011 and the Formula 34 Cruiser 2009 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Formula 31 Cruiser 2011 at 31,7 ft versus Formula 34 Cruiser 2009 at 34,0 ft. Weight tells a clearer story for trailering families: the Formula 34 Cruiser 2009 tips the scales at 1 691 lbs — 1 550 lbs less than the Formula 31 Cruiser 2011 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.

For family outings this is probably the sharpest distinction between the two. The Formula 34 Cruiser 2009 is rated for 10 passengers, while the Formula 31 Cruiser 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 34 Cruiser 2009 could be the deciding factor.

Bottom line: Choose the Formula 34 Cruiser 2009 if your priority is putting more people on the water — it handles 10 passengers and at 34,0 ft it has the deck room to back that rating up comfortably. The Formula 31 Cruiser 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Formula 31 Cruiser 2011 vs Formula 34 Cruiser 2009 — Common Questions

Which is the larger boat — the Formula 31 Cruiser 2011 or the Formula 34 Cruiser 2009?
The Formula 34 Cruiser 2009 is the longer of the two at 34,0 feet overall. The Formula 31 Cruiser 2011 comes in at 31,7 feet, making it roughly 2,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Formula 31 Cruiser 2011 or the Formula 34 Cruiser 2009?
For trailering, the Formula 31 Cruiser 2011 has the edge at 141 lbs dry weight versus 1 691 lbs for the Formula 34 Cruiser 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 2011 is Coast Guard rated for 9 passengers, while the Formula 34 Cruiser 2009 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 Cruiser 2009 measures 138" wide, compared to 132" for the Formula 31 Cruiser 2011. 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 2011 or the Formula 34 Cruiser 2009?
The Formula 34 Cruiser 2009 has the bigger tank at 206 gallons, versus 18 gallons on the Formula 31 Cruiser 2011. 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 2011 and Formula 34 Cruiser 2009 from the same manufacturer?
Yes — both the Formula 31 Cruiser 2011 and the Formula 34 Cruiser 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.
