Why we say flight

On a foil, your board flies.

A hydrofoil under the board lifts it above the water. So a Seaventi session is told like a pilot's logbook: take-offs, flights and landings, for eFoil today and every foil board next.

Pre-flight

Before you go on the water

Spot, wind, board and Watch checked on the beach, in one screen.

Flight

Your board above the water

Every moment the board rides on its foil. A fall or a touch-down ends a flight.

Instructor

Your coach, in the app

After each session, one thing to work on, from your own data.

Foil boards, foils, wings and an eFoil battery case racked under a beach shelter

Hangar

Your boards and foils

Boards, foils, wings and batteries, so each session knows what you rode.

Every session, read like a flight.

From your wrist and your phone, Seaventi records what happens above the water and tells you what to work on next. Here is a first look.

01 · Flight data

Every take-off, flight and turn, measured.

Time on foil, speed, flights and falls, from the Apple Watch or the iPhone alone.

02 · Coaching

One thing to work on, after every session.

A level per sport, and programmes built with pro riders from 2027.

03 · Safety

Always know your way back.

Return guidance and an emergency call from the wrist, even when water locks the screen.

One logbook · every Pilot

Start as an eFoil Pilot. Then fly every board.

Each sport has its Pilot. A rider who flies several keeps one history, and one level per Pilot.
