To wingsurf you need a wing and a board. Wingsurfen is possible with a snowboard, skateboard, sup and with a hydrofoil. Wingfoiling is the most popular sport, but it is also very good to learn how to wing with a SUP. On the water you also need a board leash and for some wings, like a model from Duotone, you’ll need a boom. Most wings come compete with wrist leash, but sometimes they’re sold separately.
