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

On paper these two are close siblings in the size department — Stamas 290 Express Inboard 2007 at 31,0 ft versus Stamas 290 Express Outboard 2008 at 31,0 ft. Weight tells a clearer story for trailering families: the Stamas 290 Express Outboard 2008 tips the scales at 655 lbs — 587 lbs less than the Stamas 290 Express Inboard 2007 at 68 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.

The Stamas 290 Express Inboard 2007 carries a rated maximum of 500 hp. Engine data for the Stamas 290 Express Outboard 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 290 Express Inboard 2007 carries 208 gallons versus 25 gallons in the Stamas 290 Express Outboard 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
