Both the Stamas 320 Express Outboard 2010 and the Stamas 340 Tarpon 2011 are modified-V designs, both built in fibreglass, so 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 320 Express Outboard 2010 at 34,4 ft versus Stamas 340 Tarpon 2011 at 36,2 ft. Weight tells a clearer story for trailering families: the Stamas 340 Tarpon 2011 tips the scales at 14 600 lbs - 1 900 lbs less than the Stamas 320 Express Outboard 2010 at 12 700 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 2011 is rated for 11 passengers, while the Stamas 320 Express Outboard 2010 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 Tarpon 2011 could be the deciding factor.
