Hitting
logs is a real problem, but they frequently don't sink the yacht unless they hit them just right.
After the global tsunami in the
Indian Ocean, there were huge
logs all over the place. I was amazed at people sailing on through the night with the big logs all around. On the morning
radio net, I remember a
steel boat telling how he sailed right over a log when he hit it. It destroyed his self-steering vane.
Hitting a log and sinking is extremely bad luck.
This is the worst log I have seen when sailing
offshore.
