The 360 ° with a wing foil is an aesthetic figure which gives good sensations to the rider. Not so complicated to achieve, however, you will need to have a good control of the jibe before trying.
Speed is essential to achieve a smooth 360 °. you have to start like a jibe, while keeping the wing close to you. Remember to tilt the wing while raising your rear hand to prevent the wing from dragging too much in the water. When going against (wing front to the wind at mid-rotation), push on the wing while tilting forward to avoid being thrown back.
In terms of supports, you really have to keep the pressure on the front leg, a rear leg support would release the foil immediately. The toe support to start the rotation must be moderate to maintain speed and avoid tightening the turn, which would slow down the rotation and risk plunging the board.
The ideal conditions for initiating yourself to 360 are a flat water, and a moderate wind of 15 to 20 knots. Make sure you have enough space around you, the first 360 are rarely very controlled and some swerving is to be feared.
