Learn how to prevent, manage, and recover from seasickness—so you can stay safe, confident, and capable on every passage.
Seasickness can strike anyone at sea, even experienced sailors. While it may pass quickly during a day sail, on extended coastal or offshore passages it becomes a critical health and safety concern. Left untreated, seasickness can lead to dehydration, confusion, and incapacitation. Understanding how to prevent it and how to respond when symptoms appear is essential for every sailor.
