I'm the pilot on the Mary Rose and I have a very important job. I have to make sure the ship gets to her destination safely. If I make a mistake the ship might run aground and we could all be drowned.
I'm going to tell you how I can tell where the ship is and how to plot a course to get her safely to port.
I use a number of instruments to do my job and we'll take a look at all of these as well.
