I saw this guy zipping around the Annisquam River on his Hydrofoil board the other day. He made it look fairly easy although I’m certain there must be quite the learning curve to remain so steady. Hydrofoils deflect the flow of water downwards…which then exerts a force upwards on the board. Once it picks up speed the board then lifts out of the water. Fun to watch….no doubt fun to ride as well.
