In the seas, weather conditions and conditions may not always be as desired. Sometimes the conditions can be extremely challenging and especially the visibility is extremely low. How to navigate when the visibility is low, and what to look for. The decrease in the visibility in the seas usually occurs with the fall of temperatures in the autumn months. Since there is a lot of fog and misty weather in this season, it is very difficult for sailors to navigate. The best move that sailors can do at low visibility is to keep the pace low. Since there are danger signals at any time in such weather, the sound warning systems must be clear. The sounds made by the motor of boats can sometimes prevent siren sounds from being heard. In this, you should stop your engine once in a while. You should also change the sound volume of your siren from time to time to avoid confusing it with the sound of other boats. If there is more than one ship in the area you are navigating, you should be careful not to go behind another ship. Otherwise, when the ship stops suddenly, you can collide with it. In such weather, you should follow the lighthouses and buoys that are among the navigation aids and identify the areas on your route from the navigation maps.
