Both the Stamas 320 Express Inboard 2007 and the Stamas Predator 308 2009 are modified-V designs, both built in fibreglass, so 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 320 Express Inboard 2007 measures 34,0 feet overall (2007), giving it roughly 3,3 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 320 Express Inboard 2007 tips the scales at 11 100 lbs - 2 850 lbs more than the Stamas Predator 308 2009 at 8 250 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 320 Express 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 240 gallons in the Stamas 320 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 320 Express Inboard 2007 is rated for 10 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 320 Express Inboard 2007 could be the deciding factor.
Bottom line: Choose the Stamas 320 Express Inboard 2007 if your priority is putting more people on the water - it handles 10 passengers and at 34,0 ft it has the deck room to back that rating up comfortably. The Stamas Predator 308 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
