The Marathon DN 1036 Jon 2010 is a flat-bottom design and the Marathon Grumman Heritage 2585CSP 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.

Size is the most obvious dividing line here. The Marathon Grumman Heritage 2585CSP 2011 measures 25,0 feet overall (2011), giving it roughly 15,0 additional feet of deck space compared to the Marathon DN 1036 Jon 2010 at 10,0 feet (2010). Weight tells a clearer story for trailering families: the Marathon Grumman Heritage 2585CSP 2011 tips the scales at 2 210 lbs - 2 114 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 2585CSP 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 2585CSP 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 2585CSP 2011 could be the deciding factor.
