Well done to Eva and Rose for their submission on the physics of surfing. See their covering letter below:

Surfing is a great example of how buoyancy, surface tension, mass shape and hydrodynamic forces can act together to give surfers the perfect ride. Mass and shape relate to the body of the surfers themselves. But buoyancy and hydrodynamic forces relate to the surfboard.
