Hi everyone!
I have searched the forum hard but i have been unable to find a tutorial that i have used in the past.
It is a hydrophone only tutorial that uses this method.
upon getting a hydrophone contact, up your speed a bit and point your boat directly at the target.
Now observe whether the target is swinging to pass your port or starboard. That is, if the bearing to target goes from 000 to 357, then it will pass to your port on your current heading. If the bearing goes from 000 to 003, it will pass your starboard on your current heading.
If the target will pass your port, turn 80degrees port; if the target will pass your starboard, turn 80 degrees starboard
try to find a speed that means the bearing to target remains constant.
you are now on a collision course with the target, and will eventually find it
Unfortunatly the above description is not complete.
Please help
Alex
