Stamas 320 Express Outboard 2011 vs Stamas 326 Tarpon Inboard 2012 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Stamas 320 Express Outboard 2011 and the Stamas 326 Tarpon Inboard 2012 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 320 Express Outboard 2011 at 34,4 ft versus Stamas 326 Tarpon Inboard 2012 at 32,5 ft. Weight tells a clearer story for trailering families: the Stamas 320 Express Outboard 2011 tips the scales at 127 lbs — 126 lbs more than the Stamas 326 Tarpon Inboard 2012 at 1 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.

Both boats are rated for 10 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.

Bottom line: The Stamas 320 Express Outboard 2011 and Stamas 326 Tarpon Inboard 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Stamas 320 Express Outboard 2011 vs Stamas 326 Tarpon Inboard 2012 — Common Questions

Which is the larger boat — the Stamas 320 Express Outboard 2011 or the Stamas 326 Tarpon Inboard 2012?
The Stamas 320 Express Outboard 2011 is the longer of the two at 34,4 feet overall. The Stamas 326 Tarpon Inboard 2012 comes in at 32,5 feet, making it roughly 1,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Stamas 320 Express Outboard 2011 or the Stamas 326 Tarpon Inboard 2012?
For trailering, the Stamas 326 Tarpon Inboard 2012 has the edge at 1 lbs dry weight versus 127 lbs for the Stamas 320 Express Outboard 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Stamas 320 Express Outboard 2011 is Coast Guard rated for 10 passengers, while the Stamas 326 Tarpon Inboard 2012 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Stamas 320 Express Outboard 2011 and Stamas 326 Tarpon Inboard 2012 share an 11 ft. 2 in. (3.4 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Stamas 320 Express Outboard 2011 or the Stamas 326 Tarpon Inboard 2012?
The Stamas 320 Express Outboard 2011 has the bigger tank at 316 gallons, versus 4 gallons on the Stamas 326 Tarpon Inboard 2012. That 312-gallon difference translates to roughly 936–1560 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Stamas 320 Express Outboard 2011 and Stamas 326 Tarpon Inboard 2012 from the same manufacturer?
Yes — both the Stamas 320 Express Outboard 2011 and the Stamas 326 Tarpon Inboard 2012 are built by Stamas. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
