When two boats share the same hull type — in this case both the Marathon DN 13 Utility V 2011 and the Marathon DN16T Utility V 2010 are modified vee 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?

On paper these two are close siblings in the size department — Marathon DN 13 Utility V 2011 at 13,0 ft versus Marathon DN16T Utility V 2010 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon DN16T Utility V 2010 tips the scales at 301 lbs — 286 lbs less than the Marathon DN 13 Utility V 2011 at 15 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 40 hp, the Marathon DN16T Utility V 2010 has a 25-hp advantage over the Marathon DN 13 Utility V 2011's 15-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 DN16T Utility V 2010 is rated for 7 passengers, while the Marathon DN 13 Utility V 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon DN16T Utility V 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon DN 13 Utility V 2011 comes in at 1 lbs per hp versus 8 lbs per hp for the Marathon DN16T 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.
