Hi,

If you have time, I would appreciate your solutions (radar plotting sheet,
geographical plotting, etc.).

Here is the problem (Radar) - from Ocean Navigator

Own course and speed:
150d 12.0 kt

On the radar screen (relative bearing mode):
at 0448 a "spot" at 7.0 nm 322d on the screen
at 0554 a "spot" at 5.4 nm 322d on the screen

Request :
Other ship's course
Other ship's speed

Do not hesitate to send attached files to my personnal address
pboucher@XXX.XXX

All the best for 2002

Pierre Boucher
