When two boats share the same hull type — in this case both the Marathon Grumman Classic 1460F 2012 and the Marathon Grumman Classic 1680CFP 2010 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department — Marathon Grumman Classic 1460F 2012 at 14,0 ft versus Marathon Grumman Classic 1680CFP 2010 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon Grumman Classic 1680CFP 2010 tips the scales at 146 lbs — 135 lbs less than the Marathon Grumman Classic 1460F 2012 at 11 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 — 25 hp for the Marathon Grumman Classic 1460F 2012 and 40 hp for the Marathon Grumman Classic 1680CFP 2010. 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 Grumman Classic 1680CFP 2010 is rated for 6 passengers, while the Marathon Grumman Classic 1460F 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marathon Grumman Classic 1680CFP 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Grumman Classic 1460F 2012 comes in at 0 lbs per hp versus 4 lbs per hp for the Marathon Grumman Classic 1680CFP 2010. 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.
Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: Choose the Marathon Grumman Classic 1680CFP 2010 if your priority is putting more people on the water — it handles 6 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Marathon Grumman Classic 1460F 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
