When two boats share the same hull type — in this case both the Stamas 308 Predator Outboard 2012 and the Stamas 317 Tarpon Inboard 2012 are deep 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 308 Predator Outboard 2012 measures 80,7 feet overall (2012), giving it roughly 49,1 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 308 Predator Outboard 2012 tips the scales at 825 lbs — 762 lbs more than the Stamas 317 Tarpon Inboard 2012 at 63 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.

The Stamas 308 Predator Outboard 2012 carries a rated maximum of 300 hp. Engine data for the Stamas 317 Tarpon Inboard 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 308 Predator Outboard 2012 carries 275 gallons versus 2 gallons in the Stamas 317 Tarpon Inboard 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Stamas 317 Tarpon Inboard 2012 is rated for 10 passengers, while the Stamas 308 Predator Outboard 2012 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 317 Tarpon Inboard 2012 could be the deciding factor.
