Matching a tunnel SeaArk 1860MVT 2011 against a modified vee SeaArk 2072MV 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 1860MVT 2011 at 18,0 ft versus SeaArk 2072MV 2010 at 20,1 ft. At 5 lbs and 81 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 90 hp, the SeaArk 2072MV 2010 has a 30-hp advantage over the SeaArk 1860MVT 2011's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The SeaArk 2072MV 2010 is rated for 13 passengers, while the SeaArk 1860MVT 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 2072MV 2010 could be the deciding factor.
Bottom line: Choose the SeaArk 2072MV 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 1860MVT 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
