When two boats share the same hull type — in this case both the Stamas 250 Tarpon Outboard 2007 and the Stamas 320 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 320 Express Inboard 2007 measures 34,0 feet overall (2007), giving it roughly 8,0 additional feet of deck space compared to the Stamas 250 Tarpon Outboard 2007 at 26,0 feet (2007). At 43 lbs and 111 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Stamas 250 Tarpon Outboard 2007 carries a rated maximum of 400 hp. Engine data for the Stamas 320 Express Inboard 2007 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 250 Tarpon Outboard 2007 carries 162 gallons versus 24 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 250 Tarpon Outboard 2007 caps at 8. 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 250 Tarpon Outboard 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
