Wednesday evening I thought I had a great start. But apparently I was over early and I was called back. So where is the end of the line, at the committee end, that is? (What part of the committe boat is the committee end of the line?)
The answer is found in the sailing instructions for the race. Usually, it's a staff with an orange flag, or some other vertical feature (like the mast on a sailboat). It must
be described in the sailing instructions.
You can avoid being early (most of the time) by taking a line sight - I like to line up the stern of the signal boat with the pin and a feature on the far shore (distinctive tree, house, landmark, etc.). Then, when you're on the line, you can judge where you are by looking at the pin and your line sight. By sighting off the stern of the signal boat, you allow a bit of buffer, since you're sitting back from the bow of your boat.
