I think sleep deprivation is an issue only with singles. I always sail the long distances with my first mate, so, yes - I sometimes lack sleep, but there is no issue of any trim degradation from lack of sleep (other than being less than present-minded over short periods of time).
What I understand by degradation of fitness level is that the strength of body muscles gets lowered and the respiratory fitness falls dramatically and they are not retrieved by getting good rest and more regular lifestyle.
I can explain this by the following example - We started from Sweden
in 2004 and just one year later we were in FP. All the way we swam and trekked whenever possible. Before our departure, I could run, bike and climb for hours without much fatigue. Now upon our arrival in Gambiers I found that it was next to impossible to climb the mountains there - actually walking the village was quite painful in the first week. And our passage
was nothing special - only 72 days.
Now the biggest and nastiest surprise came when (after 6+ years of intensive sailing/cruising) we made a longer stop in Las Palmas
where we have access to the swimming pool, gym and a park where we can again run our traditional 3x30x130. It took me a year to get back to the point where I can run 10k comfortably.
So, my observation is that extended passages and liveaboard
life-style very seriously and negatively influence our fitness and athletic capability, and probably the worst part of it is that we are not always aware of just how much.
