Wind Surf is a five-masted sailing yacht built to combine the scale of a cruise ship with the reach of a private vessel small enough to slip into coves and harbors larger ships can't touch. The film goes aboard to show how the ship works, from its sail rigging and navigation systems to the engineering that lets it run under wind power alongside diesel propulsion. Crew members and officers walk through daily operations, covering everything from route planning around weather to the logistics of provisioning and maintaining a vessel of this size at sea. The documentary also spends time in the guest spaces, showing how the ship balances luxury amenities with the practicalities of sailing, and looks at the shipyard engineering and design choices that went into making a sailing yacht this large seaworthy. It is a straightforward engineering and operations profile rather than a travel promo, built around access to the ship's mechanics and the people who run it day to day.
