Watersports.

Cleaner watersports: electric foils, solar boats and silent motors replace 2-stroke noise and fumes, and the playground gets cleaner as the tech gets better. That is the forecast. The suits will discover it in 2029 and call it a surprise.

Lift Foils and Fliteboard sell eFoils that fly silently above the water. Awake and Radinn build electric jetboards that hit highway speeds. Seabob drags you underwater like a dolphin, the Cudajet jetpack turns swimmers into torpedoes. Candela makes electric hydrofoil boats, Silent-Yachts crosses oceans on solar, Torqeedo electrifies the outboard, and SailGP's foiling F50s hit 100 km/h.

Surface watersports equipment grows from $13.6 billion in 2023 to $19.58 billion by 2030, surfing alone past $6 billion. If you think watersports is still plastic boards and gas-guzzling jet skis, you are living in a sepia postcard. The ocean is going full Iron Man.
