When two boats share the same hull type — in this case both the Stamas 290 Express Outboard 2009 and the Stamas 310 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?

On paper these two are close siblings in the size department — Stamas 290 Express Outboard 2009 at 31,0 ft versus Stamas 310 Express Outboard 2010 at 32,5 ft. Weight tells a clearer story for trailering families: the Stamas 290 Express Outboard 2009 tips the scales at 655 lbs — 557 lbs more than the Stamas 310 Express Outboard 2010 at 98 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 310 Express Outboard 2010 tops out at 500 hp. Engine specs for the Stamas 290 Express Outboard 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Stamas 290 Express Outboard 2009 carries 25 gallons versus 3 gallons in the Stamas 310 Express Outboard 2010. 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.
