Matching a tunnel SeaArk 1872MVJT 2009 against a modified vee SeaArk 1872SS 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 1872MVJT 2009 at 18,0 ft versus SeaArk 1872SS 2010 at 18,0 ft. At 75 lbs and 65 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.
Both boats share a closely matched power ceiling — 80 hp for the SeaArk 1872MVJT 2009 and 80 hp for the SeaArk 1872SS 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 1872MVJT 2009 is rated for 12 passengers, while the SeaArk 1872SS 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk 1872MVJT 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk 1872SS 2010 comes in at 1 lbs per hp versus 1 lbs per hp for the SeaArk 1872MVJT 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the SeaArk 1872MVJT 2009 if your priority is putting more people on the water — it handles 12 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The SeaArk 1872SS 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
