Matching a modified vee SeaArk 1860MV 2010 against a tunnel SeaArk BayRunner MVJT 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 1860MV 2010 at 18,0 ft versus SeaArk BayRunner MVJT 2010 at 20,1 ft. Weight tells a clearer story for trailering families: the SeaArk BayRunner MVJT 2010 tips the scales at 119 lbs — 114 lbs less than the SeaArk 1860MV 2010 at 5 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.
The power gap is worth calling out. Rated to 140 hp, the SeaArk BayRunner MVJT 2010 has a 80-hp advantage over the SeaArk 1860MV 2010's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk BayRunner MVJT 2010 could be the deciding factor.

The SeaArk 1860MV 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
