Coming out of Hanalei Bay in an Atkin Eric design in ferro with the beam carried well forward and aft, right into the 10' swells practically immediately I was sick for 30 miserable hours. Later on nearly three weeks we went through a gale of fifty mph winds from astern with seas from three directions occasionally breaking over the decks. I suddenly realized as I was cooking lunch below that I hadn't a twinge of illness at all in those conditions. Go figure those sea legs.
