Matching a tunnel SeaArk 1872MVT Super Tunnel Jon 2013 against a modified vee SeaArk RX 180 2013 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 1872MVT Super Tunnel Jon 2013 at 18,0 ft versus SeaArk RX 180 2013 at 18,0 ft. At 75 lbs and 51 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 1872MVT Super Tunnel Jon 2013 and 90 hp for the SeaArk RX 180 2013. 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.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk RX 180 2013 comes in at 1 lbs per hp versus 1 lbs per hp for the SeaArk 1872MVT Super Tunnel Jon 2013. 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.
