I recently went on a cruise and had no problem getting weed on the boat, all i did was put it in a bag then another bag and put it in a shampoo bottle with shampoo in it. i think this is the best method to bring weed on a boat. another thing is im sure you can get away from your wife for atleast an hour so you can search for weed on one of these islands cause ive been to almost every island in the carrabian and i found weed everywhere and some good shit too. happy tokes and good luck
