Matching a deep vee Marathon DN 12 Utility V 2010 against a flat Marathon DN 1436 Jon 2010 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 DN 12 Utility V 2010 at 11,7 ft versus Marathon DN 1436 Jon 2010 at 14,1 ft. Weight tells a clearer story for trailering families: the Marathon DN 12 Utility V 2010 tips the scales at 121 lbs — 108 lbs more than the Marathon DN 1436 Jon 2010 at 13 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 — 10 hp for the Marathon DN 12 Utility V 2010 and 15 hp for the Marathon DN 1436 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.
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 DN 1436 Jon 2010 comes in at 1 lbs per hp versus 12 lbs per hp for the Marathon DN 12 Utility V 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.
Bottom line: The Marathon DN 1436 Jon 2010 at 14,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marathon DN 12 Utility V 2010 at 11,7 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
