I use a MUCH SIMPLER way to plot an intercept, it's easier and very accurate... Stock game... You are given the location, angle, and "rough speed".

1. Draw the path: There is a tail on the mark, draw a line from the tip of the tail through the ship and far off ahead of it. You can pull the line far ahead and still adjust the line to match the direction as close as you can. If you want to be exact or not do any math you can draw a second line from the actual point of the ship and not the tail... then delete the original line to get it out of the way.

2. Now draw a line from your sub to their ships original location, DON'T click it(lock it in), just mentally note the distance, then start adjusting the line along the path until the two distances match.

Now, if you travel there at the same speed you would both hit that spot at the same time.

3. Simply adjust one or more factors to insure you arrive before them.
3a. You can travel to that location at a faster speed. Assume 6-7.. Go 8-9 knots... for example.
3b. measure the distance so theirs is a little longer than yours. So maybe your line intersects at 25km on their line and 21km on your line. If you travel at the same speed you'll arrive at that point and their ship should be about 4km away... depending on your skills and their speed you should be able to adjust your position and calculate your solution in plenty of time.

Expand your skills: As you do this over and over again you'll get better at it. and you can adjust more factors like... if you think they are traveling 6 knots and you want to travel at 12. Simply have your ship double the distance they travel and you should arrive at the same place, same time(This is useful for distant ships where you are going to have to out distance them to intercept). Eventually you'll be able to adjust your angle and speed(together) and be confident with your math in your head.

And there you have it! No angles, no trigonometry, etc... simple as it gets, JUST TWO LINES and look at their lengths.

That's just getting to the ship... I have other techniques I use to put it down.

Does that help anybody?
