Both the Stamas 340 Express Outboard 2006 and the Stamas 340 Tarpon 2009 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?

Size is the most obvious dividing line here. The Stamas 340 Express Outboard 2006 measures 41,0 feet overall (2006), giving it roughly 5,0 additional feet of deck space compared to the Stamas 340 Tarpon 2009 at 36,0 feet (2009). Weight tells a clearer story for trailering families: the Stamas 340 Tarpon 2009 tips the scales at 14 600 lbs - 800 lbs less than the Stamas 340 Express Outboard 2006 at 13 800 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 2006 is rated for 12 passengers, while the Stamas 340 Tarpon 2009 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Outboard 2006 could be the deciding factor.
