We understand that cigarettes are the currency of exchange in prison (we have no personal experience with prison… but we suspect there are very few similarities with cruising). The currency of exchange on a sailboat is information. The medium of exchange is USB sticks.
Charts, tracks, software, media, guidebooks, photos, and so many other things are exchanged on USB sticks. Bring lots… preferably some water-resistant ones.
