Hi, you made the correct drawing. But in this case your speed turns out to be to big. If you draw a circle of 60 (6 kts) or 90 (9kts) you wil see is intersects. After that you know your angle and still can steam up with 12 kts but you will arrive very early. It is all about math. If you understand it ones it is a peace of cake.

In this case you could draw a cirkel from position 60 towards your sub position, divide by 10 and you have your intersection speed. Intersection point would be position 60. Of course make sure your speed is a little higher because maybe your target is running 7 kts.

If the circle intercepts in two places, use the point closest to your sub to determine your angle.

In another ocassion, if your cirkel from 120 (12kts) would fit inside this triangle, and 12kts was your max speed, You should forget about intercepting this target.

Greetings, Marcel
