Matching a flat Marathon DN 1036 Jon 2010 against a pontoon Marathon Grumman Heritage 2585CP 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.
Size is the most obvious dividing line here. The Marathon Grumman Heritage 2585CP 2011 measures 25,0 feet overall (2011), giving it roughly 24,0 additional feet of deck space compared to the Marathon DN 1036 Jon 2010 at 1,0 feet (2010). Weight tells a clearer story for trailering families: the Marathon Grumman Heritage 2585CP 2011 tips the scales at 221 lbs — 125 lbs less than the Marathon DN 1036 Jon 2010 at 96 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 140 hp, the Marathon Grumman Heritage 2585CP 2011 has a 137-hp advantage over the Marathon DN 1036 Jon 2010's 3-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 Grumman Heritage 2585CP 2011 is rated for 16 passengers, while the Marathon DN 1036 Jon 2010 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon Grumman Heritage 2585CP 2011 could be the deciding factor.
Bottom line: Choose the Marathon Grumman Heritage 2585CP 2011 if your priority is putting more people on the water — it handles 16 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Marathon DN 1036 Jon 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
