When two boats share the same hull type — in this case both the Stamas 290 Tarpon Outboard 2007 and the Stamas 340 Tarpon Inboard 2007 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 290 Tarpon Outboard 2007 carries a rated maximum of 500 hp. Engine data for the Stamas 340 Tarpon Inboard 2007 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 2007 is rated for 10 passengers, while the Stamas 290 Tarpon Outboard 2007 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 2007 could be the deciding factor.
