Re: Sleeping underway risk
I confess I've never tried sleeping on board a sailing boat in anything more than 35 knots , 4 - 5 metre swell and with only occasional white caps. Max speed around 7 - 8 knots. That was bumpy but not out of control. We were close hauled so lee berth was pretty secure.
I could well understand the worry about injury in wilder seas or on board a faster racing machine where they are coming off the top at speed but in a slow boat surely less of a problem provided decent lee cloths and the like.
Those are my principles, and if you don't like them... well, I have others. Julius Henry Marx.
