Harvesting on a boat is a little different than harvesting on land. On land you get your chips & head for the door. On the boat there is no place to hide. If you get them while on a boat, quickly give them to a partner to hold until you get on land.If they go looking for you & find you but not the roulettes there is little they can do. Incidently I was just on a boat. I speak from experience. Will trade these wet roulettes for other wet roulettes that I need.
