Marathon Grumman Classic 1680CFP 2011 vs Marathon Utility V - DN16T 2009 — Same Brand, Different Boat

Matching a pontoon Marathon Grumman Classic 1680CFP 2011 against a modified vee Marathon Utility V - DN16T 2009 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 Grumman Classic 1680CFP 2011 at 16,0 ft versus Marathon Utility V - DN16T 2009 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon Utility V - DN16T 2009 tips the scales at 301 lbs — 155 lbs less than the Marathon Grumman Classic 1680CFP 2011 at 146 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 Grumman Classic 1680CFP 2011 and 40 hp for the Marathon Utility V - DN16T 2009. 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.

For family outings this is probably the sharpest distinction between the two. The Marathon Utility V - DN16T 2009 is rated for 7 passengers, while the Marathon Grumman Classic 1680CFP 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon Utility V - DN16T 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Grumman Classic 1680CFP 2011 comes in at 4 lbs per hp versus 8 lbs per hp for the Marathon Utility V - DN16T 2009. 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.

Bottom line: Choose the Marathon Utility V - DN16T 2009 if your priority is putting more people on the water — it handles 7 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Marathon Grumman Classic 1680CFP 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Marathon Grumman Classic 1680CFP 2011 vs Marathon Utility V - DN16T 2009 — Common Questions

Which is the larger boat — the Marathon Grumman Classic 1680CFP 2011 or the Marathon Utility V - DN16T 2009?
The Marathon Utility V - DN16T 2009 is the longer of the two at 16,0 feet overall. The Marathon Grumman Classic 1680CFP 2011 comes in at 16,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Marathon Grumman Classic 1680CFP 2011 or the Marathon Utility V - DN16T 2009?
For trailering, the Marathon Grumman Classic 1680CFP 2011 has the edge at 146 lbs dry weight versus 301 lbs for the Marathon Utility V - DN16T 2009. 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.
How many people can each boat hold?
The Marathon Grumman Classic 1680CFP 2011 is Coast Guard rated for 6 passengers, while the Marathon Utility V - DN16T 2009 is certified for 7. 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 has the better power-to-weight ratio?
The Marathon Grumman Classic 1680CFP 2011 has a better power-to-weight ratio at 4 lbs per hp compared to 8 lbs per hp for the Marathon Utility V - DN16T 2009. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Marathon Grumman Classic 1680CFP 2011 measures 96" wide, compared to 7" for the Marathon Utility V - DN16T 2009. 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.

Yes — both the Marathon Grumman Classic 1680CFP 2011 and the Marathon Utility V - DN16T 2009 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.
