Boat positions
The boat positions on the 657 can differ from the true boat positions:
Distress: The position is the distress waypoint, which is where the boat was when it sent the distress message.
Polled boats: The position is where the boat was when you last polled the boat.
Buddy track: The position is where the boat was when your radio last polled the boat.
