Stamas 317 Tarpon Inboard 2012 vs Stamas 370 Express Inboard 2007 — Same Brand, Different Boat

The Stamas 317 Tarpon Inboard 2012 vs Stamas 370 Express Inboard 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Stamas 370 Express Inboard 2007 measures 39,0 feet overall (2007), giving it roughly 7,4 additional feet of deck space compared to the Stamas 317 Tarpon Inboard 2012 at 31,6 feet (2012). Weight tells a clearer story for trailering families: the Stamas 370 Express Inboard 2007 tips the scales at 2 113 lbs — 2 050 lbs less than the Stamas 317 Tarpon Inboard 2012 at 63 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.

For family outings this is probably the sharpest distinction between the two. The Stamas 370 Express Inboard 2007 is rated for 11 passengers, while the Stamas 317 Tarpon Inboard 2012 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 370 Express Inboard 2007 could be the deciding factor.

Bottom line: Choose the Stamas 370 Express Inboard 2007 if your priority is putting more people on the water — it handles 11 passengers and at 39,0 ft it has the deck room to back that rating up comfortably. The Stamas 317 Tarpon Inboard 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
