When two boats share the same hull type — in this case both the Stamas 310 Tarpon Inboard 2006 and the Stamas 340 Tarpon Inboard 2006 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?

The Stamas 310 Tarpon Inboard 2006 carries a rated maximum of 500 hp. Engine data for the Stamas 340 Tarpon Inboard 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Stamas 340 Tarpon Inboard 2006 is rated for 10 passengers, while the Stamas 310 Tarpon Inboard 2006 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Tarpon Inboard 2006 could be the deciding factor.
