Single-handed sailing is also known as solo sailing or one-man sailing. This type of sailing is when a sailor navigates and operates a boat or yacht alone with no crew on board. Solo sailors may also refer to their type of sailing as solo cruising or single-handed racing. Other synonyms for single-handed sailing include unaccompanied sailing, skippering solo, and lone sailing. These terms all refer to the challenging and often intense experience of navigating a vessel on one's own, relying solely on their own skills and abilities. Solo sailing requires a great deal of mental and physical stamina, making it a specialized and often thrilling activity for experienced sailors.
