When two boats share the same hull type — in this case both the Formula 310 Bowrider 2013 and the Formula 40 Performance Cruiser 2008 are modified 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 310 Bowrider 2013 measures 31,0 feet overall (2013), giving it roughly 27,0 additional feet of deck space compared to the Formula 40 Performance Cruiser 2008 at 4,0 feet (2008). Weight tells a clearer story for trailering families: the Formula 310 Bowrider 2013 tips the scales at 9 875 lbs — 7 600 lbs more than the Formula 40 Performance Cruiser 2008 at 2 275 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 40 Performance Cruiser 2008 is rated for 12 passengers, while the Formula 310 Bowrider 2013 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Formula 40 Performance Cruiser 2008 could be the deciding factor.
