Formula 31 Cruiser 2006 vs Formula Boats 400 FX8 2013 — Same Brand, Different Boat
The Formula 31 Cruiser 2006 vs Formula Boats 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.
The Formula Boats 400 FX8 2013 tops out at 430 hp. Engine specs for the Formula 31 Cruiser 2006 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Formula Boats 400 FX8 2013 carries 25 gallons versus 18 gallons in the Formula 31 Cruiser 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Formula Boats 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 Boats 400 FX8 2013 could be the deciding factor.
Bottom line: Choose the Formula Boats 400 FX8 2013 if your priority is putting more people on the water — it handles 12 passengers and at 42,0 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.
