When two boats share the same hull type — in this case both the Fountain 31 CC 2009 and the Fountain 38 EC 2009 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 Fountain 38 EC 2009 measures 38,0 feet overall (2009), giving it roughly 7,0 additional feet of deck space compared to the Fountain 31 CC 2009 at 31,0 feet (2009). At 58 lbs and 15 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.

The power gap is worth calling out. Rated to 425 hp, the Fountain 38 EC 2009 has a 423-hp advantage over the Fountain 31 CC 2009's 2-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fountain 38 EC 2009 carries 296 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 38 EC 2009 is rated for 11 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 38 EC 2009 could be the deciding factor.
