When two boats share the same hull type — in this case both the Fountain 31 Center Console 2008 and the Fountain 38 Lightning 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?
Size is the most obvious dividing line here. The Fountain 38 Lightning 2012 measures 38,0 feet overall (2012), giving it roughly 7,0 additional feet of deck space compared to the Fountain 31 Center Console 2008 at 31,0 feet (2008). At 58 lbs and 98 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.
Both boats share a closely matched power ceiling — 2 hp for the Fountain 31 Center Console 2008 and 2 hp for the Fountain 38 Lightning 2012. 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 31 Center Console 2008 carries 204 gallons versus 18 gallons in the Fountain 38 Lightning 2012. 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 Lightning 2012 is rated for 11 passengers, while the Fountain 31 Center Console 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 Lightning 2012 could be the deciding factor.
Bottom line: Choose the Fountain 38 Lightning 2012 if your priority is putting more people on the water — it handles 11 passengers and at 38,0 ft it has the deck room to back that rating up comfortably. The Fountain 31 Center Console 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
