When two boats share the same hull type — in this case both the Stamas 290 Tarpon Inboard 2007 and the Stamas 310 Express Outboard 2010 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?

On paper these two are close siblings in the size department — Stamas 290 Tarpon Inboard 2007 at 31,0 ft versus Stamas 310 Express Outboard 2010 at 32,5 ft. At 6 lbs and 98 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Stamas 310 Express Outboard 2010 tops out at 500 hp. Engine specs for the Stamas 290 Tarpon Inboard 2007 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 2 gal and 3 gal — so range won't be a tiebreaker here.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
