I have a question, if you have a large ship and a small ship perfectly parallel, the small ship is exacly in the middle of the large ship (so pegs lined up) and there is a small rock in between them, if you measure corner to corner the rock isn't in either line of sight, but if you measure middle to middle flat to flat is it, which is the line of sight and measurement that is used? flat to flat with rock or corner to corner (front or back as both or equal distance) and no rock?
I ask because it has happened one time before. I insisted corners opponent insisted flat.
