When two boats share the same hull type — in this case both the SeaArk 2060MV Super Jon 2013 and the SeaArk Forecast 170C 2011 are modified vee 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?
Size is the most obvious dividing line here. The SeaArk 2060MV Super Jon 2013 measures 20,1 feet overall (2013), giving it roughly 3,1 additional feet of deck space compared to the SeaArk Forecast 170C 2011 at 17,0 feet (2011). Weight tells a clearer story for trailering families: the SeaArk Forecast 170C 2011 tips the scales at 775 lbs — 721 lbs less than the SeaArk 2060MV Super Jon 2013 at 54 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 SeaArk 2060MV Super Jon 2013 and 75 hp for the SeaArk Forecast 170C 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 SeaArk 2060MV Super Jon 2013 is rated for 6 passengers, while the SeaArk Forecast 170C 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2060MV Super Jon 2013 could be the deciding factor.
Bottom line: Choose the SeaArk 2060MV Super Jon 2013 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk Forecast 170C 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
