I used to use a big dry bag. Last year I began using only the Think Tank Glass Limo. If it was gonna be rough, I would put the gear inside plastic bags or small, light dry bags. I’d make sure to sit on the side with the wind to my back so that I could shelter the bag with my body. And I did carry some gear in my Xtra-Hand Vest. I made sure that I did not fall getting into or out of the zodiac. You never carry your gear when getting in or out; it is always carried by the staff and passed to you. So far I have a prefect record 🙂

ps: it sounds as if you might be interested in the Southern Ocean Photography Guide that am working on…
