Boat cards are a necessity if you cruise
much at all and want to be friendly with other cruisers. You might want to be careful about distributing email
addresses. When we first started cruising we had our email addresses on the cards. Wasn't long until we were receiving a great deal of unsolicited and unwanted emails from people and businesses we did not know. So we changed our boat cards to reflect something like:
Sailors know how to address the Sailmail and Winlink email addresses. If the card falls into hands of non-sailors, they do not know how to use those email addresses. And, of course, if they don't know how to use Sailmail or Winlink email addresses, they can always go to our blogsite and contact us from there. This cut way down on the number of unwanted emails received.
Just a thought you might want to consider.
Note: those are NOT our real Sailmail and Winlink #s
