When two boats share the same hull type — in this case both the Stamas 290 Tarpon Inboard 2006 and the Stamas 340 Express Outboard 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 340 Express Outboard 2007 measures 41,0 feet overall (2007), giving it roughly 10,0 additional feet of deck space compared to the Stamas 290 Tarpon Inboard 2006 at 31,0 feet (2006). Weight tells a clearer story for trailering families: the Stamas 340 Express Outboard 2007 tips the scales at 138 lbs — 132 lbs less than the Stamas 290 Tarpon Inboard 2006 at 6 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 Express Outboard 2007 is rated for 12 passengers, while the Stamas 290 Tarpon Inboard 2006 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 Express Outboard 2007 could be the deciding factor.
