Marathon DN 1036 Jon 2011 vs Marathon Seneca Utility 12 2008 — Same Brand, Different Boat

Matching a flat Marathon DN 1036 Jon 2011 against a modified vee Marathon Seneca Utility 12 2008 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.

Size is the most obvious dividing line here. The Marathon Seneca Utility 12 2008 measures 11,0 feet overall (2008), giving it roughly 10,0 additional feet of deck space compared to the Marathon DN 1036 Jon 2011 at 1,0 feet (2011). At 96 lbs and 121 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 — 3 hp for the Marathon DN 1036 Jon 2011 and 10 hp for the Marathon Seneca Utility 12 2008. 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.

For family outings this is probably the sharpest distinction between the two. The Marathon Seneca Utility 12 2008 is rated for 3 passengers, while the Marathon DN 1036 Jon 2011 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon Seneca Utility 12 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Seneca Utility 12 2008 comes in at 12 lbs per hp versus 32 lbs per hp for the Marathon DN 1036 Jon 2011. 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: Choose the Marathon Seneca Utility 12 2008 if your priority is putting more people on the water — it handles 3 passengers and at 11,0 ft it has the deck room to back that rating up comfortably. The Marathon DN 1036 Jon 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

Marathon DN 1036 Jon 2011 vs Marathon Seneca Utility 12 2008 — Common Questions

Which is the larger boat — the Marathon DN 1036 Jon 2011 or the Marathon Seneca Utility 12 2008?
The Marathon Seneca Utility 12 2008 is the longer of the two at 11,0 feet overall. The Marathon DN 1036 Jon 2011 comes in at 1,0 feet, making it roughly 10,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Marathon DN 1036 Jon 2011 or the Marathon Seneca Utility 12 2008?
For trailering, the Marathon DN 1036 Jon 2011 has the edge at 96 lbs dry weight versus 121 lbs for the Marathon Seneca Utility 12 2008. 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.
Which boat can handle a bigger outboard?
The Marathon Seneca Utility 12 2008 is rated to a maximum of 10 hp, giving it the larger power ceiling. The Marathon DN 1036 Jon 2011 tops out at 3 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Marathon DN 1036 Jon 2011 is Coast Guard rated for 2 passengers, while the Marathon Seneca Utility 12 2008 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 Seneca Utility 12 2008 has a better power-to-weight ratio at 12 lbs per hp compared to 32 lbs per hp for the Marathon DN 1036 Jon 2011. 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 DN 1036 Jon 2011 and Marathon Seneca Utility 12 2008 from the same manufacturer?
Yes — both the Marathon DN 1036 Jon 2011 and the Marathon Seneca Utility 12 2008 are built by Marathon. 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.
