Stamas 320 Express Inboard 2006 vs Stamas 392 Aegean Inboard Diesel 2012 — Same Brand, Different Boat

Matching a modified vee Stamas 320 Express Inboard 2006 against a deep vee Stamas 392 Aegean Inboard Diesel 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Stamas 392 Aegean Inboard Diesel 2012 measures 39,2 feet overall (2012), giving it roughly 5,2 additional feet of deck space compared to the Stamas 320 Express Inboard 2006 at 34,0 feet (2006). Weight tells a clearer story for trailering families: the Stamas 392 Aegean Inboard Diesel 2012 tips the scales at 2 113 lbs — 2 002 lbs less than the Stamas 320 Express Inboard 2006 at 111 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.

For family outings this is probably the sharpest distinction between the two. The Stamas 392 Aegean Inboard Diesel 2012 is rated for 11 passengers, while the Stamas 320 Express Inboard 2006 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 392 Aegean Inboard Diesel 2012 could be the deciding factor.

Bottom line: Choose the Stamas 392 Aegean Inboard Diesel 2012 if your priority is putting more people on the water — it handles 11 passengers and at 39,2 ft it has the deck room to back that rating up comfortably. The Stamas 320 Express Inboard 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
