When two boats share the same hull type — in this case both the Stamas 340 Express Inboard 2006 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?

Size is the most obvious dividing line here. The Stamas 340 Express Inboard 2006 measures 36,0 feet overall (2006), giving it roughly 5,3 additional feet of deck space compared to the Stamas Predator 308 2009 at 30,7 feet (2009). Weight tells a clearer story for trailering families: the Stamas 340 Express Inboard 2006 tips the scales at 18 155 lbs — 17 330 lbs more than the Stamas Predator 308 2009 at 825 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 340 Express Inboard 2006 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 35 gallons in the Stamas 340 Express Inboard 2006. 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 340 Express Inboard 2006 is rated for 11 passengers, while the Stamas Predator 308 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Inboard 2006 could be the deciding factor.
