Matching a tunnel SeaArk 1872JTPCC Jet Tunnel Pro 2013 against a modified vee SeaArk RXV 186 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 1872JTPCC Jet Tunnel Pro 2013 at 18,0 ft versus SeaArk RXV 186 2013 at 18,5 ft. At 78 lbs and 9 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 1872JTPCC Jet Tunnel Pro 2013 and 90 hp for the SeaArk RXV 186 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.
Bottom line: The SeaArk 1872JTPCC Jet Tunnel Pro 2013 and SeaArk RXV 186 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
