Matching a modified vee SeaArk BayRunner 2008 against a tunnel SeaArk Tunnel Jon 1872MVT 2008 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.
Size is the most obvious dividing line here. The SeaArk Tunnel Jon 1872MVT 2008 measures 18,0 feet overall (2008), giving it roughly 16,0 additional feet of deck space compared to the SeaArk BayRunner 2008 at 2,0 feet (2008). At 119 lbs and 75 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 BayRunner 2008 has a 60-hp advantage over the SeaArk Tunnel Jon 1872MVT 2008's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 12 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 BayRunner 2008 comes in at 1 lbs per hp versus 1 lbs per hp for the SeaArk Tunnel Jon 1872MVT 2008. 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 Tunnel Jon 1872MVT 2008 at 18,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The SeaArk BayRunner 2008 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
