Leave the course recorder on in port to see when it’s past due for service, if it doesn’t draw a straight line in port it’s past due for service

Sir pwdi ba kukuha ng gyro error habang nasa jetty o berth object sighted by sunrise o sunset?

[@dbiyaheromasterseaman]

Pwedeng pwede either by ABC method or amplitude kung may horizon. As long as my celestial body pwede kau. Salamat
