When two boats share the same hull type — in this case both the Stamas 250 Tarpon 2009 and the Stamas 310 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?

Size is the most obvious dividing line here. The Stamas 310 Express Inboard 2007 measures 32,0 feet overall (2007), giving it roughly 6,0 additional feet of deck space compared to the Stamas 250 Tarpon 2009 at 26,0 feet (2009). Weight tells a clearer story for trailering families: the Stamas 250 Tarpon 2009 tips the scales at 549 lbs — 444 lbs more than the Stamas 310 Express Inboard 2007 at 105 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 Inboard 2007 tops out at 500 hp. Engine specs for the Stamas 250 Tarpon 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Stamas 250 Tarpon 2009 carries 106 gallons versus 3 gallons in the Stamas 310 Express Inboard 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Stamas 310 Express Inboard 2007 is rated for 9 passengers, while the Stamas 250 Tarpon 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 310 Express Inboard 2007 could be the deciding factor.
