In contrast to regular surfing where leaning on a rail generates a lift on the other side, learning to foil requires equal pressure on both sides as pushing on one side generates lift against it. Foiling provides a unique experience of flying on the water with minimal resistance due to the board being elevated off the water entirely via the use of a larger foil while the efoil is useful for beginners to get a feel of flying on the water by having the board's motion partially assisted by a motor.
