Stamas 289 Tarpon Outboard 2012 vs Stamas 320 Express Inboard 2006 — Same Brand, Different Boat

Matching a deep vee Stamas 289 Tarpon Outboard 2012 against a modified vee Stamas 320 Express Inboard 2006 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 Inboard 2006 measures 34,0 feet overall (2006), giving it roughly 5,3 additional feet of deck space compared to the Stamas 289 Tarpon Outboard 2012 at 28,8 feet (2012). At 55 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 289 Tarpon Outboard 2012 carries a rated maximum of 450 hp. Engine data for the Stamas 320 Express Inboard 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 22 gal and 24 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Stamas 320 Express Inboard 2006 is rated for 10 passengers, while the Stamas 289 Tarpon Outboard 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 Inboard 2006 could be the deciding factor.

Bottom line: Choose the Stamas 320 Express Inboard 2006 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 289 Tarpon Outboard 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.
