Bottom Loading in Surfboard Design

Seems like “bottom loading” should be an important factor for surfboard design, especially since surfboards are “planing hulls.” bottom loading = displacement mass divided by the planing surface area Should be possible to determine a general, desired bottom surface area range for any given rider’s individual weight. Planing speed is significantly affected by displacement mass (load) and planing hull surface area. Did some searching and found a general recommendation (no substantiating source…

The Volume Variable

Surfboard volume is a variable that is both quantitative and qualitative. Surfboard volume is the product of its dimensions. Buoyancy is affected by volume and load. Buoyancy and width affect stability. Stability affects ease of paddling and riding/standing. Buoyancy affects submerged volume/submerged surface area which affects drag. Drag affects acceleration, affecting time and distance needed to reach critical velocities. (There are 2 critical velocities in surfing, take-off and planing…
