Both the Fountain 31 Tournament Edition 2008 and the Fountain 38 SFC I/O 2010 are modified-V designs, both built in fibreglass, so 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 Fountain 38 SFC I/O 2010 measures 38,0 feet overall (2010), giving it roughly 7,0 additional feet of deck space compared to the Fountain 31 Tournament Edition 2008 at 31,0 feet (2008). Weight tells a clearer story for trailering families: the Fountain 38 SFC I/O 2010 tips the scales at 15 800 lbs - 10 000 lbs less than the Fountain 31 Tournament Edition 2008 at 5 800 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 share a closely matched power ceiling - 2 hp for the Fountain 31 Tournament Edition 2008 and 2 hp for the Fountain 38 SFC I/O 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Fountain 38 SFC I/O 2010 carries 296 gallons versus 204 gallons in the Fountain 31 Tournament Edition 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Fountain 38 SFC I/O 2010 is rated for 11 passengers, while the Fountain 31 Tournament Edition 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fountain 38 SFC I/O 2010 could be the deciding factor.
