Updated in matte-black color with cobalt accented wheels, the Scupper Swift has an adjustable-width axle that makes it the best sit-on-top cart on the market. Slide your boat easily on to, or off of, the coated and cushioned uprights and away you go! A super beefy 35mm anodized frame can take all sorts of abuse, while the airless, vibration reducing, solid urethane tires eliminate all flat tire hassle. Maximum load capacity is 150 pounds.
