When two boats share the same hull type — in this case both the Stamas 290 Tarpon Inboard 2007 and the Stamas Predator 308 2009 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 Tarpon Inboard 2007 at 31,0 ft versus Stamas Predator 308 2009 at 30,7 ft. Weight tells a clearer story for trailering families: the Stamas Predator 308 2009 tips the scales at 825 lbs — 819 lbs less than the Stamas 290 Tarpon Inboard 2007 at 6 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 Predator 308 2009 tops out at 300 hp. Engine specs for the Stamas 290 Tarpon Inboard 2007 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Stamas Predator 308 2009 carries 275 gallons versus 2 gallons in the Stamas 290 Tarpon Inboard 2007. 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.
