Navigation subject

Last week Capt. Gines recall to us the meaning of navigation. The first topic that he discusses to us is about tides and currents. And our present lesson for this week is about compass. After he finishes discussing the tides and currents, I am now able to differentiate the tide from current. Tide is the rise and fall of ocean water in a day while current is the horizontal movement of water. And now in our present lesson which is about compass and bearings, I have learned where is the point of reference of each compass pointing to the north that is affected with deviation, variation, and compass errors.
