Matching a modified vee Marathon Cayuga 16 2010 against a pontoon Marathon Grumman Classic 1980E 2011 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 Cayuga 16 2010 at 16,0 ft versus Marathon Grumman Classic 1980E 2011 at 19,0 ft. Weight tells a clearer story for trailering families: the Marathon Grumman Classic 1980E 2011 tips the scales at 2 015 lbs — 1 973 lbs less than the Marathon Cayuga 16 2010 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.
The power gap is worth calling out. Rated to 40 hp, the Marathon Cayuga 16 2010 has a 30-hp advantage over the Marathon Grumman Classic 1980E 2011's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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.
Bottom line: The Marathon Grumman Classic 1980E 2011 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marathon Cayuga 16 2010 at 16,0 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.
