When two boats share the same hull type — in this case both the Stamas 290 Express Outboard 2008 and the Stamas 340 Tarpon 2008 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 340 Tarpon 2008 measures 36,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Stamas 290 Express Outboard 2008 at 31,0 feet (2008). Weight tells a clearer story for trailering families: the Stamas 290 Express Outboard 2008 tips the scales at 655 lbs — 509 lbs more than the Stamas 340 Tarpon 2008 at 146 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 340 Tarpon 2008 is rated for 11 passengers, while the Stamas 290 Express Outboard 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Tarpon 2008 could be the deciding factor.
