Alex, I'm sure you are a reasonable person. As Dog Paddle suggests, and as everybody else who read your last post immediately thought: Would the Polynesians, St. Brendan, etc. have deliberately chosen not to carry a compass, had one been available to them? The answer is clear. You have no case: a compass costs very little, is easily attached to the deck, and is quite a help in properly orienting one's chart to the actual location, and orienting oneself to the chart. As a user of charts, you know all this. You're not getting anywhere with this argument; maybe a compass will show you the correct path.
