Matching a modified vee Stamas 290 Express Inboard 2007 against a deep vee Stamas 308 Predator Outboard 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Stamas 308 Predator Outboard 2012 measures 80,7 feet overall (2012), giving it roughly 49,7 additional feet of deck space compared to the Stamas 290 Express Inboard 2007 at 31,0 feet (2007). Weight tells a clearer story for trailering families: the Stamas 308 Predator Outboard 2012 tips the scales at 825 lbs — 757 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 power gap is worth calling out. Rated to 500 hp, the Stamas 290 Express Inboard 2007 has a 200-hp advantage over the Stamas 308 Predator Outboard 2012's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Stamas 308 Predator Outboard 2012 carries 275 gallons versus 208 gallons in the Stamas 290 Express 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.
