I keep getting a false anchor alarm on my Raymarine RL80C multiple display/chart plotter . The anchor alarm is off yet it activates randomly. E mailing and calling Raymarine has sent me on many goose chases with no solution. Any suggestions as to how to stop the random anchor alarm ? In addition to the RL80C I have connected to the system the following Raymarine electronics. ST6001 autopilot controller, S3 course computers, ST80 multiple display and a new standard horizon VHF ( connected to the course computer to pick up GPS position). Hopefully someone has already solved this problem.
