When two boats share the same hull type — in this case both the Stamas 290 Express Outboard 2009 and the Stamas 320 Express Inboard 2007 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?

On paper these two are close siblings in the size department — Stamas 290 Express Outboard 2009 at 31,0 ft versus Stamas 320 Express Inboard 2007 at 34,0 ft. Weight tells a clearer story for trailering families: the Stamas 290 Express Outboard 2009 tips the scales at 655 lbs — 544 lbs more than the Stamas 320 Express Inboard 2007 at 111 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 320 Express Inboard 2007 is rated for 10 passengers, while the Stamas 290 Express Outboard 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 320 Express Inboard 2007 could be the deciding factor.
