what's on a boat card?
My son and I are sailing to Abaco this summer and we want a boat or boat business card. I'm not sure what to call it. He's a teacher and the cruise is tied into education (Bahamas Ecological Studies). I've heard that these cards are useful to give to new friends or the authorities. My question is what info goes on the card? I know boat name, a web address, home port and name of crew make sense. Should there be some sort of home address? What about phone numbers? Is there anything else I'm missing?
