When two boats share the same hull type — in this case both the Stamas 340 Express Inboard 2007 and the Stamas 340 Express Outboard 2010 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 340 Express Outboard 2010 measures 41,0 feet overall (2010), giving it roughly 5,0 additional feet of deck space compared to the Stamas 340 Express Inboard 2007 at 36,0 feet (2007). Weight tells a clearer story for trailering families: the Stamas 340 Express Inboard 2007 tips the scales at 18 155 lbs — 18 017 lbs more than the Stamas 340 Express Outboard 2010 at 138 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 340 Express Outboard 2010 is rated for 12 passengers, while the Stamas 340 Express Inboard 2007 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Outboard 2010 could be the deciding factor.
