Matching a modified vee SeaArk 1860 Pro LD 2012 against a tunnel SeaArk 2072JTPCC 2010 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 — SeaArk 1860 Pro LD 2012 at 18,0 ft versus SeaArk 2072JTPCC 2010 at 20,1 ft. Weight tells a clearer story for trailering families: the SeaArk 1860 Pro LD 2012 tips the scales at 515 lbs — 431 lbs more than the SeaArk 2072JTPCC 2010 at 84 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 — 80 hp for the SeaArk 1860 Pro LD 2012 and 90 hp for the SeaArk 2072JTPCC 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 SeaArk 2072JTPCC 2010 is rated for 13 passengers, while the SeaArk 1860 Pro LD 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2072JTPCC 2010 could be the deciding factor.
Bottom line: Choose the SeaArk 2072JTPCC 2010 if your priority is putting more people on the water — it handles 13 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk 1860 Pro LD 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
