The Stamas 310 Express Inboard 2007 is a modified-V design and the Stamas 326 Aegean Outboard 2012 is a deep-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.

On paper these two are close siblings in the size department - Stamas 310 Express Inboard 2007 at 32,0 ft versus Stamas 326 Aegean Outboard 2012 at 32,5 ft.

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.

Rated to 600 hp, the Stamas 326 Aegean Outboard 2012 has a 100-hp advantage over the Stamas 310 Express Inboard 2007's 500-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 300 gal and 300 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Stamas 326 Aegean Outboard 2012 is rated for 10 passengers, while the Stamas 310 Express Inboard 2007 caps at 9.
