Both the Fountain 31 CC 2009 and the Fountain 48 Express Cruiser 2011 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 48 Express Cruiser 2011 measures 48,5 feet overall (2011), giving it roughly 17,5 additional feet of deck space compared to the Fountain 31 CC 2009 at 31,0 feet (2009). Weight tells a clearer story for trailering families: the Fountain 48 Express Cruiser 2011 tips the scales at 24 000 lbs - 18 200 lbs less than the Fountain 31 CC 2009 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 CC 2009 and 3 hp for the Fountain 48 Express Cruiser 2011. 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 48 Express Cruiser 2011 carries 470 gallons versus 204 gallons in the Fountain 31 CC 2009. 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 48 Express Cruiser 2011 is rated for 14 passengers, while the Fountain 31 CC 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fountain 48 Express Cruiser 2011 could be the deciding factor.
