The Nautical Chart on a Charter

Sailing Personnel Emergencies

As the skipper of a vessel, you are expected to be able to handle situations thrust upon you at a moment’s notice. Many of these situations are boat-related issues, but there are also crew injury issues for which you should be prepared to assess and handle at least enough until professional assistance arrives.

Diagram illustrating true wind, apparent wind, and boat speed effects on sail, influencing sailing dynamics.

Sailing Wind Velocity & Direction

The faster the boat sails into the wind, the more the apparent wind speed increases and the more it feels like it is coming from the front of the boat. They say  "The apparent wind is forward of the true wind". This means the apparent wind feels like it comes from a more forward direction than the true wind.
