I was able to take a couple of pictures of the "Prawn Boat".
As you can see it is a very sophisticated system!!
At least I didn't go overboard!!! Oh yes -- there is a story to that. I came home to his last helper walking around the house in my white fluffy dressing gown -- he went overboard!! Jim ended up rowing the boat - with a foot of water - back to shore with the helper hanging on to the stern --- LOL. Always an adventure :)))
