My standard procedure (I think I got it from Rockin Robbins):
1. Draw a circle around my boat, I think 6 nm just to be sure.
2. Draw a line from the radar contact to the edge of the circle.
3. Draw a line from the contact to the other side of the circle.
(At this point, you've drawn what looks like an ice cream cone)
4. Observe the contact. If he enters the cone, his course will bring him within 6 nm of your boat, so it's time to get under water. If he moves outside the cone, you're probably safe.

Switching to manual plotting and targeting made this a completely different game for me.
