Matching a tunnel SeaArk 2072JTPCC 2011 against a modified vee SeaArk X180 SC 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 — SeaArk 2072JTPCC 2011 at 20,1 ft versus SeaArk X180 SC 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the SeaArk X180 SC 2011 tips the scales at 905 lbs — 821 lbs less than the SeaArk 2072JTPCC 2011 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 — 90 hp for the SeaArk 2072JTPCC 2011 and 90 hp for the SeaArk X180 SC 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 2072JTPCC 2011 is rated for 13 passengers, while the SeaArk X180 SC 2011 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 2011 could be the deciding factor.

The SeaArk X180 SC 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.
