When two boats share the same hull type — in this case both the Stamas 340 Express Inboard 2006 and the Stamas 340 Tarpon 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?

On paper these two are close siblings in the size department — Stamas 340 Express Inboard 2006 at 36,0 ft versus Stamas 340 Tarpon Outboard 2007 at 34,0 ft. Weight tells a clearer story for trailering families: the Stamas 340 Express Inboard 2006 tips the scales at 18 155 lbs — 18 141 lbs more than the Stamas 340 Tarpon Outboard 2007 at 14 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 Inboard 2006 is rated for 11 passengers, while the Stamas 340 Tarpon Outboard 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Inboard 2006 could be the deciding factor.
