Displacement Hulls
The experience of hull riding is in the connection with the wave flow for the rider rather than the onlooker. First of all planing. Planing is when the craft skims over the surface of the water. Displacement is when the craft ploughs it's way through the water, very much like the hull of a boat. Like it or not, pretty much all surfboards displace water to some extent. If you know of a surfboard that doesn't displace to some extent, please let me know, I'd very much like to hear from you.
Surfboards are a combination of displacement and planing hull.
