A Planing Hull is not Always the Fastest
Nose rocker is an important aspect of a surfboard, it keeps the board from diving under. The down side of nose rocker is that it creates...
Evolution and the Planning Hull
The image below is of a surfboard planning hull. Most surfboards are flat from end to end. A few have concaves and Vee's in the tail...
Fluid Dynamics
The following video is a simulation of a ship hull pushing water out of its path as it moves forward. The ship's bow parts water and...
Hydrodynamic Resistance
Speed on water generates resistance. Water resists compression. Water does not compress due to inter molecular hydrogen bonding. Bonding...
Hulls
There are many surfboard hull shapes; most can be classified into three categories. Each category has conditions which optimize...
Speed + Water = Resistance
Water is adhesive, it sticks to things. Water sticks to almost anything. More specifically for ocean enthusiasts, it sticks to ships,...
Diminishing Returns
Nose rocker aids performance, by keeping the surfboard from diving underwater. As a board moves faster, it generates gravity force. ...
Surfboard Nose Rocker May Inhibit Wave Entry
High nose rocker may inhibit a take off or getting on a wave. Nose rocker creates a bow on the surfboard's underside. The bow is a...
Increase Performance Add Weight to a Surfboard
Surfers occasionally add weights to their surfboards for a boost in riding through chop or penetrating strong winds. Weights give the...
Happy New Year! Responsible and Safe Fluid Dynamics
Fluid Dynamics All vessels move in water by moving water. Surfers generate waves while riding waves. At the start of a ride a surfer...
