Sailing in 40 - 50 feet seas is a little interesting because your body seems to be like a pinball as you traverse down each passageway. After the first day it hurts even worse as you are bounced to and fro again and instead of hitting a new piece of virgin flesh you generally hit the places yopu bruised the day before.
I can only remember one time I was even remotely close to being seasick. We had just gotten underway from Colon, Panama and headed out into the Caribbean. As we passed the Cristobal Breakwater we were immediately hit by 15 - 20 feet swells on the stbd bow. after an hour or so I was not feeling that great and went into the head hoping I would release whatever my stomach contained. After waiting what seemed like forever, probably only like 10 minutes, I still was unable to release the mother lode so I climbed into my rack.
An hour or two later I awoke and felt like a million bucks. Over the years I have found this to be rather useful whentver I felt like less than a salty sailor, take a nap and I wake up feeling great.
I do remember one time going from Colon, Panama to Rosie Roads, PR and we were taking a beating on the stbd bow the entire trip. When we arrived in PR I saw the stbd bow anchor was lost on the trip. I called the Master and let him know. The master, knowing my tendency to pull one's leg about a thing or two, didn't believe I was telling the truth and had to come down to see for himself that the stbd anchor was gone. Still it was a rather fun trip nonetheless.
