Matching a tunnel Shallow Sport 18 ft. Classic 2013 against a flat Shallow Sport 18 ft. Sport 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 — Shallow Sport 18 ft. Classic 2013 at 18,4 ft versus Shallow Sport 18 ft. Sport 2013 at 18,0 ft. At 75 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.
