Matching a tunnel SeaArk 1872 Tunnel Pro (CC) 2012 against a modified vee SeaArk DXS 1860 SLD 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 1872 Tunnel Pro (CC) 2012 at 18,0 ft versus SeaArk DXS 1860 SLD 2013 at 18,0 ft. At 78 lbs and 53 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 140 hp, the SeaArk 1872 Tunnel Pro (CC) 2012 has a 80-hp advantage over the SeaArk DXS 1860 SLD 2013's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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 1872 Tunnel Pro (CC) 2012 comes in at 1 lbs per hp versus 1 lbs per hp for the SeaArk DXS 1860 SLD 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.
Bottom line: Performance buyers should lean toward the SeaArk 1872 Tunnel Pro (CC) 2012 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the SeaArk DXS 1860 SLD 2013 with its 60-hp rating is the more economical daily driver.
