The last few days were busy in port and am just getting past all that paperwork, so let me show you a sight we see in the Panama at the locks. For passing lines to the ships, you have thin lines (8mm Polyproplene) with a weighed end that needs to be thrown to the shore or the ship by which you can pass the remaining lines. The line throwers in Panama actually have tournaments and this is the board on which it is held. You throw the line through the bulls eye, and also over the top pole.
I have thrown lines across many railings towards many ports and Let me assure you that its an art that I doubt I'll ever acquire!
