Marathon Jon - DN 1236 2008 vs Marathon Utility V - DN 12 2009 — Same Brand, Different Boat

Matching a flat Marathon Jon - DN 1236 2008 against a deep vee Marathon Utility V - DN 12 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Marathon Jon - DN 1236 2008 at 12,0 ft versus Marathon Utility V - DN 12 2009 at 11,0 ft. Weight tells a clearer story for trailering families: the Marathon Utility V - DN 12 2009 tips the scales at 121 lbs — 110 lbs less than the Marathon Jon - DN 1236 2008 at 11 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 — 7 hp for the Marathon Jon - DN 1236 2008 and 10 hp for the Marathon Utility V - DN 12 2009. 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.

Both boats are rated for 3 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Jon - DN 1236 2008 comes in at 2 lbs per hp versus 12 lbs per hp for the Marathon Utility V - DN 12 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: The Marathon Jon - DN 1236 2008 and Marathon Utility V - DN 12 2009 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.

Marathon Jon - DN 1236 2008 vs Marathon Utility V - DN 12 2009 — Common Questions

Which is the larger boat — the Marathon Jon - DN 1236 2008 or the Marathon Utility V - DN 12 2009?
The Marathon Jon - DN 1236 2008 is the longer of the two at 12,0 feet overall. The Marathon Utility V - DN 12 2009 comes in at 11,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Marathon Jon - DN 1236 2008 or the Marathon Utility V - DN 12 2009?
For trailering, the Marathon Jon - DN 1236 2008 has the edge at 11 lbs dry weight versus 121 lbs for the Marathon Utility V - DN 12 2009. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Marathon Jon - DN 1236 2008 is Coast Guard rated for 3 passengers, while the Marathon Utility V - DN 12 2009 is certified for 3. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Marathon Jon - DN 1236 2008 has a better power-to-weight ratio at 2 lbs per hp compared to 12 lbs per hp for the Marathon Utility V - DN 12 2009. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Are the Marathon Jon - DN 1236 2008 and Marathon Utility V - DN 12 2009 from the same manufacturer?
Yes — both the Marathon Jon - DN 1236 2008 and the Marathon Utility V - DN 12 2009 are built by Marathon. That means shared dealer networks, common parts availability, and consistent build quality across the line.
