The innovative surfing tech making waves | BBC

A hydrofoil surfboard, also known as a foil board, is a surfboard with two underwater wings and a long carbon-fibre rod, or mast, reaching downwards from the bottom. The wings (also constructed of carbon fibre) are propelled through the water when the speed and momentum of the sea are adequate, raising the surfboard and its user into the air. As a result, many foil boards now have electric-powered propellers integrated into their masts, allowing them to be utilized even when there are no waves. This implies that the user may go surfing on lakes and rivers as well as on flat seas. While hydrofoil technology has been around for almost a century in the boating world, it wasn’t until the early 2000s that it began to find its way into surfing. The first commercially available electric-powered hydrofoil surfboards, or ‘efoils,’ were produced in 2018 by the Puerto Rican company Lift Hydrofoils.
