Fountain 38 SFC I/O 2012 vs Fountain 38 SFC OB 2010 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Fountain 38 SFC I/O 2012 and the Fountain 38 SFC OB 2010 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?

On paper these two are close siblings in the size department — Fountain 38 SFC I/O 2012 at 38,0 ft versus Fountain 38 SFC OB 2010 at 38,0 ft. At 158 lbs and 145 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 38 SFC I/O 2012 and 3 hp for the Fountain 38 SFC OB 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 2012 carries 296 gallons versus 4 gallons in the Fountain 38 SFC OB 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Fountain 38 SFC I/O 2012 and Fountain 38 SFC OB 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Fountain 38 SFC I/O 2012 vs Fountain 38 SFC OB 2010 — Common Questions

Which is the larger boat — the Fountain 38 SFC I/O 2012 or the Fountain 38 SFC OB 2010?
The Fountain 38 SFC OB 2010 is the longer of the two at 38,0 feet overall. The Fountain 38 SFC I/O 2012 comes in at 38,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Fountain 38 SFC I/O 2012 or the Fountain 38 SFC OB 2010?
For trailering, the Fountain 38 SFC OB 2010 has the edge at 145 lbs dry weight versus 158 lbs for the Fountain 38 SFC I/O 2012.

How many people can each boat hold?
The Fountain 38 SFC I/O 2012 is Coast Guard rated for 11 passengers, while the Fountain 38 SFC OB 2010 is certified for 11.

Do these boats require an oversize trailer permit to tow on US highways?
Both the Fountain 38 SFC I/O 2012 and Fountain 38 SFC OB 2010 share an 10 ft. 6 in. (3.2 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Fountain 38 SFC I/O 2012 or the Fountain 38 SFC OB 2010?

Are the Fountain 38 SFC I/O 2012 and Fountain 38 SFC OB 2010 from the same manufacturer?
Yes — both the Fountain 38 SFC I/O 2012 and the Fountain 38 SFC OB 2010 are built by Fountain. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
