Matching a modified vee Marathon DN 16SST 2013 against a pontoon Marathon Grumman Classic 1680CFP 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 16SST 2013 at 16,0 ft versus Marathon Grumman Classic 1680CFP 2010 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon Grumman Classic 1680CFP 2010 tips the scales at 146 lbs — 104 lbs less than the Marathon DN 16SST 2013 at 42 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 — 40 hp for the Marathon DN 16SST 2013 and 40 hp for the Marathon Grumman Classic 1680CFP 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 6 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 16SST 2013 comes in at 1 lbs per hp versus 4 lbs per hp for the Marathon Grumman Classic 1680CFP 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 16SST 2013 and Marathon Grumman Classic 1680CFP 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
