I've been doing this boat thing since I was a kid. At some point it became apparent that the things I'd been doing for so many years I could no longer do without injuring myself, sometimes seriously. After tearing the ligaments of the left bicep so badly that the muscle now resides at the shoulder, I saw the need to think before acting. Now, even the simplest tasks like picking up a mooring pennant, need to be thought through so I don't injure myself. It is an unfortunate fact that I am just no longer able to horse around a 70k pound boat. It isn't that I don't do things, it's that I understand my limits and do them with forethought.
