When two boats share the same hull type — in this case both the Stamas 320 Express Outboard 2011 and the Stamas 370 Express Inboard 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 Stamas 370 Express Inboard 2008 measures 39,0 feet overall (2008), giving it roughly 4,6 additional feet of deck space compared to the Stamas 320 Express Outboard 2011 at 34,4 feet (2011). Weight tells a clearer story for trailering families: the Stamas 370 Express Inboard 2008 tips the scales at 2 113 lbs — 1 986 lbs less than the Stamas 320 Express Outboard 2011 at 127 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 Stamas 370 Express Inboard 2008 is rated for 11 passengers, while the Stamas 320 Express Outboard 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 370 Express Inboard 2008 could be the deciding factor.
