Congratulations on your first SH sailing!
For me, going out sailing with a few (one, two or three friends. Not more) is wonderful. But sailing alone is almost mystical.
I learned sailing singlehandling, so I did lots of stupid mistakes and it took me plenty of time to find out about things that are so obvious now.... (like wondering why the
autopilot seemed to get tired and act funny after working for several hours. And then realizing "Hmmmm. Maybe it's not the
autopilot. Maybe it's the batteries.... You idiot!").
But the most important lesson of all was finding out that sh**t happens even in calm seas. Last September I heard three stories directly from the people involved:
- While sailing solo in real calm seas, almost no wind, no boats around, a man I know was walking along the deck and a sudden wave out of nowhere thrown him overboard. He could grasp the handrail with both hands so he remained hunging upside down kissing the hull with his feet over his head for like a minute or two. When he thought he could not hold anymore, a new lonely wave helped him back onboard.
- Another guy I know was sailing with a friend also in very calm seas. His friend was at the bow doing something and he stood up on the stern to take a leak. But he slided and felt overboard. From the water he saw the stern of the boat getting away and his friend on the bow focusing his task... He freaked out and had a hearth attack! Luckily the friend noticed and steered back, and managed to get him onboard and called the coastguards, who took him to the hospital on time.
- The third story was sad. A young professional sailor (28) fell overboard and his two inexperienced friends didn't know anything about boats. The wind took them to ground peacefully on a beach. But the sailor's body was never found.
After learning about these stories, against my natural risk-taking mentality, I started putting the
harness and lifeline on when sailing solo or with unexperienced crew. And now I see my previous solo navigations as almost suicidal.
SD and others already told you, but take it seriously: never leave the cockpit without hooking the lifeline to your
harness. And at night or on rough seas, wear it even in the cockpit.
