When two boats share the same hull type — in this case both the Marathon DN 1036 Jon 2010 and the Marathon DN 1236 Jon 2010 are flat designs with aluminum 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 Marathon DN 1236 Jon 2010 measures 12,0 feet overall (2010), giving it roughly 11,0 additional feet of deck space compared to the Marathon DN 1036 Jon 2010 at 1,0 feet (2010). At 96 lbs and 11 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 2010 and 7 hp for the Marathon DN 1236 Jon 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.

For family outings this is probably the sharpest distinction between the two. The Marathon DN 1236 Jon 2010 is rated for 3 passengers, while the Marathon DN 1036 Jon 2010 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon DN 1236 Jon 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon DN 1236 Jon 2010 comes in at 2 lbs per hp versus 32 lbs per hp for the Marathon DN 1036 Jon 2010. 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.
