When two boats share the same hull type — in this case both the Stamas 320 Express Outboard 2008 and the Stamas 340 Express Outboard 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?

Size is the most obvious dividing line here. The Stamas 340 Express Outboard 2007 measures 41,0 feet overall (2007), giving it roughly 7,0 additional feet of deck space compared to the Stamas 320 Express Outboard 2008 at 34,0 feet (2008). At 127 lbs and 138 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.

For family outings this is probably the sharpest distinction between the two. The Stamas 340 Express Outboard 2007 is rated for 12 passengers, while the Stamas 320 Express Outboard 2008 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Outboard 2007 could be the deciding factor.
