Marathon DN B-14SST 2007 vs Marathon Grumman Heritage 2385CP 2012 — Same Brand, Different Boat

The Marathon DN B-14SST 2007 vs Marathon Grumman Heritage 2385CP 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Marathon Grumman Heritage 2385CP 2012 measures 23,0 feet overall (2012), giving it roughly 9,0 additional feet of deck space compared to the Marathon DN B-14SST 2007 at 14,0 feet (2007). Weight tells a clearer story for trailering families: the Marathon Grumman Heritage 2385CP 2012 tips the scales at 2 045 lbs — 1 731 lbs less than the Marathon DN B-14SST 2007 at 314 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 115 hp, the Marathon Grumman Heritage 2385CP 2012 has a 90-hp advantage over the Marathon DN B-14SST 2007's 25-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 2385CP 2012 is rated for 14 passengers, while the Marathon DN B-14SST 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon Grumman Heritage 2385CP 2012 could be the deciding factor.

Bottom line: Choose the Marathon Grumman Heritage 2385CP 2012 if your priority is putting more people on the water — it handles 14 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Marathon DN B-14SST 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Marathon DN B-14SST 2007 vs Marathon Grumman Heritage 2385CP 2012 — Common Questions

Which is the larger boat — the Marathon DN B-14SST 2007 or the Marathon Grumman Heritage 2385CP 2012?
The Marathon Grumman Heritage 2385CP 2012 is the longer of the two at 23,0 feet overall. The Marathon DN B-14SST 2007 comes in at 14,0 feet, making it roughly 9,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Marathon DN B-14SST 2007 or the Marathon Grumman Heritage 2385CP 2012?
For trailering, the Marathon DN B-14SST 2007 has the edge at 314 lbs dry weight versus 2 045 lbs for the Marathon Grumman Heritage 2385CP 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Marathon Grumman Heritage 2385CP 2012 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Marathon DN B-14SST 2007 tops out at 25 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Marathon DN B-14SST 2007 is Coast Guard rated for 5 passengers, while the Marathon Grumman Heritage 2385CP 2012 is certified for 14. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Marathon Grumman Heritage 2385CP 2012 measures 102" wide, compared to 65" for the Marathon DN B-14SST 2007. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Marathon DN B-14SST 2007 and Marathon Grumman Heritage 2385CP 2012 from the same manufacturer?
Yes — both the Marathon DN B-14SST 2007 and the Marathon Grumman Heritage 2385CP 2012 are built by Marathon. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
