Matching a flat Marathon Jon - DN 1036 2009 against a modified vee Marathon Seneca 14RS 2013 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 14RS 2013 measures 14,3 feet overall (2013), giving it roughly 13,3 additional feet of deck space compared to the Marathon Jon - DN 1036 2009 at 1,0 feet (2009). Weight tells a clearer story for trailering families: the Marathon Seneca 14RS 2013 tips the scales at 228 lbs — 132 lbs less than the Marathon Jon - DN 1036 2009 at 96 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.

The power gap is worth calling out. Rated to 25 hp, the Marathon Seneca 14RS 2013 has a 22-hp advantage over the Marathon Jon - DN 1036 2009's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Marathon Seneca 14RS 2013 is rated for 5 passengers, while the Marathon Jon - DN 1036 2009 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 14RS 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Seneca 14RS 2013 comes in at 9 lbs per hp versus 32 lbs per hp for the Marathon Jon - DN 1036 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.
