n. recreation or sport of surfing with a longboard
Wikipedia
Longboarding is the act of riding on a Longboard. Longboarding also has competitive races down hill, with some riders reaching speeds exceeding 50 miles per hour. A longboard varies in shape and size unlike its set counterpart, the skateboard, and has more stability, traction and durability due to larger wheel size and lower wheel durometers. Many, but not all longboards, use trucks (axles) that contain different geometric parameters than a skateboard as well. These factors and their variation have given way to a variety of disciplines, functions and purposes for a longboard. The angles at which some longboards can turn, as well as their ability to coast long distances make them more suitable for cruising, and commuting, on streets than regular skateboards.
