SeaArk Red Runner 180 2007 vs SeaArk RX 872 2013 — Same Brand, Different Boat

The SeaArk Red Runner 180 2007 vs SeaArk RX 872 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — SeaArk Red Runner 180 2007 at 18,0 ft versus SeaArk RX 872 2013 at 18,0 ft. At 9 lbs and 11 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 — 115 hp for the SeaArk Red Runner 180 2007 and 130 hp for the SeaArk RX 872 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 872 2013 comes in at 0 lbs per hp versus 0 lbs per hp for the SeaArk Red Runner 180 2007. 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: The SeaArk Red Runner 180 2007 and SeaArk RX 872 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.
