The Marathon DN 16SSC 2010 is a modified-V design and the Marathon Grumman Classic 1680CFP 2011 is a pontoon design, so you're likely deciding between two noticeably 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 16SSC 2010 at 16,0 ft versus Marathon Grumman Classic 1680CFP 2011 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon Grumman Classic 1680CFP 2011 tips the scales at 1 460 lbs - 1 040 lbs less than the Marathon DN 16SSC 2010 at 420 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 16SSC 2010 and 40 hp for the Marathon Grumman Classic 1680CFP 2011. 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 16SSC 2010 comes in at 11 lbs per hp versus 37 lbs per hp for the Marathon Grumman Classic 1680CFP 2011. 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.
