The Stamas 317 Tarpon Inboard 2012 is a deep-V design and the Stamas 340 Tarpon 2009 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Stamas 340 Tarpon 2009 measures 36,0 feet overall (2009), giving it roughly 4,4 additional feet of deck space compared to the Stamas 317 Tarpon Inboard 2012 at 31,6 feet (2012). Weight tells a clearer story for trailering families: the Stamas 340 Tarpon 2009 tips the scales at 14 600 lbs - 8 300 lbs less than the Stamas 317 Tarpon Inboard 2012 at 6 300 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 2009 is rated for 11 passengers, while the Stamas 317 Tarpon Inboard 2012 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 2009 could be the deciding factor.
