Speaking of ski masks; in 1989 we were boarded by three guys on a 30 foot fishing boat all wearing ski masks while anchored off Karamata, a small island off the coast of Borneo. Kitty and our two boys were down below doing school work while I had been on deck doing some maintenance chores, when they came aboard. I began yelling at them to get off my boat and they in turn were yelling back at me in some Indonesian language or dialect I did not understand. About five minutes into the yelling match, Kitty stuck her head out the hatch and handed out three Cokes and a pack of cigarettes. The three men took off their ski masks and with a big smile accepted the Cokes sat down and began to drink. We conversed in sign language for a while and then they got up, brought me over to their boat, opened the hold and loaded me with fresh fish. As they sailed away they all gave me the thumbs up.
Later we learned that many of the fishermen and construction workers in that part of the world wear ski masks to protect their faces from the sun. Two years ago, while we were in the Bahamas, we met a woman who was from that area and she said that where she is from, people don't understand the principal of private property and they couldn't understand why we were angry at them for coming aboard. the first picture below is of the three fishermen while I was on their boat and the second is of another fisherman in Thailand wearing a ski mask.
