Detailed Evaluation & Buyer Recommendation
Formula 31 Cruiser 2006 vs Formula 400 FX8 2013 — Same Brand, Different Boat
The Formula 31 Cruiser 2006 vs Formula 400 FX8 2013 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 FX8 2013 measures 41,5 feet overall (2013), giving it roughly 8,5 additional feet of deck space compared to the Formula 31 Cruiser 2006 at 33,0 feet (2006). 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 FX8 2013 is rated for 12 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 400 FX8 2013 could be the deciding factor.
Bottom line: Choose the Formula 400 FX8 2013 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 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.
