Matching a pontoon Marathon Grumman Journey 1885C 2013 against a modified vee Marathon Owasco 16 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.
On paper these two are close siblings in the size department — Marathon Grumman Journey 1885C 2013 at 18,0 ft versus Marathon Owasco 16 2011 at 16,0 ft. Weight tells a clearer story for trailering families: the Marathon Grumman Journey 1885C 2013 tips the scales at 1 561 lbs — 1 510 lbs more than the Marathon Owasco 16 2011 at 51 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 — 70 hp for the Marathon Grumman Journey 1885C 2013 and 50 hp for the Marathon Owasco 16 2011. 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 Journey 1885C 2013 is rated for 10 passengers, while the Marathon Owasco 16 2011 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 Journey 1885C 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Marathon Owasco 16 2011 comes in at 1 lbs per hp versus 22 lbs per hp for the Marathon Grumman Journey 1885C 2013. 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 Grumman Journey 1885C 2013 if your priority is putting more people on the water — it handles 10 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Marathon Owasco 16 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
