RE: Sea sickness. I don't know those waters at all, but anyplace can get rougher than normal. Within 30 minutes of being below deck, I started getting sea sick in relatively calm waters, so it's very individual. However, taking sea sickness pills allowed me to survive some truly monstrous seas with no problem. We hit a 2-day period where they had to pump out the pools 'cause they were sloshing across the decks. The 750ft ship's bow was actually lurching out of the swells for a while. I still wasn't sea sick when on "the pill" so to speak. YMMV.
