Detailed Evaluation & Buyer Recommendation

Stamas 289 Tarpon Inboard 2012 vs Stamas 320 Express Outboard 2010 — Same Brand, Different Boat

Matching a deep vee Stamas 289 Tarpon Inboard 2012 against a modified vee Stamas 320 Express Outboard 2010 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 320 Express Outboard 2010 measures 34,4 feet overall (2010), giving it roughly 5,7 additional feet of deck space compared to the Stamas 289 Tarpon Inboard 2012 at 28,8 feet (2012). Weight tells a clearer story for trailering families: the Stamas 289 Tarpon Inboard 2012 tips the scales at 669 lbs — 542 lbs more than the Stamas 320 Express Outboard 2010 at 127 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 289 Tarpon Inboard 2012 carries a rated maximum of 240 hp. Engine data for the Stamas 320 Express Outboard 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 320 Express Outboard 2010 carries 316 gallons versus 106 gallons in the Stamas 289 Tarpon Inboard 2012. 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 Outboard 2010 is rated for 10 passengers, while the Stamas 289 Tarpon Inboard 2012 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 Outboard 2010 could be the deciding factor.

Bottom line: Choose the Stamas 320 Express Outboard 2010 if your priority is putting more people on the water — it handles 10 passengers and at 34,4 ft it has the deck room to back that rating up comfortably. The Stamas 289 Tarpon Inboard 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
