Detailed Evaluation & Buyer Recommendation
Formula 31 Cruiser 2011 vs Formula 400 FX8 2011 — Which Deep Vee Fits Your Needs?
When two boats share the same hull type — in this case both the Formula 31 Cruiser 2011 and the Formula 400 FX8 2011 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?
Size is the most obvious dividing line here. The Formula 400 FX8 2011 measures 41,5 feet overall (2011), giving it roughly 9,8 additional feet of deck space compared to the Formula 31 Cruiser 2011 at 31,7 feet (2011). At 141 lbs and 171 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 FX8 2011 is rated for 12 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 400 FX8 2011 could be the deciding factor.
Bottom line: Choose the Formula 400 FX8 2011 if your priority is putting more people on the water — it handles 12 passengers and at 41,5 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.
