In The Witcher 3: Wild Hunt, sailing is an available form of transport facilitated through the use of small sailing boats. To use a boat, Geralt must first board the vessel, then take the helm using the E key. To navigate, he can use W to move forward, A to steer towards the left (port) and D to steer to towards the right (starboard). He can also reverse by using S.
Boats can sink if they take too much damage, and their health is indicated by an on-screen display that appears when traveling by boat. Enemies will try to attack while you’re sailing, and they can rip apart a boat quickly. Running aground rocks or beaches can also damage a boat, so careful navigation is required.
Geralt can also Fast Travel while on a boat, but only to destinations accessible via a water route. To Fast Travel by boat, open the panel for World Map while at the helm of a ship. You can travel to any point marked with symbol of anchor.
