A compass by itself is insufficient to indicate position of a vessel. Your compass merely aligns itself with the lines of magnetic force at your location, and from this, and a knowledge of the deviation of these local lines from true, you will have an indication of the North direction.
You may find the local deviation by comparing your compass north with the position of the Sun at local noon. NOT the time zone noon!
If you are lying off some land features that you can identify on the chart, then by taking cross bearings to a few of these, your position may be deduced.

What meaning of anchor bearing?
A set of crossed compass bearings as observed from a vessel laying at anchor to identify the ships position.
How do you apply Latitude And Speed Correction in gyro compass?
To apply latitude and speed correction in a gyro compass, first, determine the gyro's latitude and speed of the vessel. The gyro compass typically drifts due to the Earth's rotation and the vessel's speed, so adjustments are made based on the vessel's position. For latitude corrections, apply a correction factor based on the difference between true and magnetic north, while speed corrections account for the influence of speed over ground on the gyro's performance. Regularly monitoring and adjusting these parameters ensures accurate heading information.
What are the parts of gyro compass and its function?
A gyro compass consists of a spinning gyroscope, a compass card, and a correcting mechanism. The spinning gyroscope maintains its orientation in space and serves as the reference point for navigation. The compass card aligns with the gyro's axis to indicate the heading of the vessel. The correcting mechanism adjusts for errors due to the vessel's motion to provide accurate heading information.
How can you get the positon of land by terrestial navigation?
To determine your position using terrestrial navigation, you can utilize landmarks, maps, and a compass. First, identify prominent features in your surroundings and cross-reference them with a map to establish your location. By taking compass bearings of these landmarks, you can triangulate your position. Additionally, using techniques like dead reckoning, which involves tracking your speed and direction of travel, can further refine your position assessment.
What is the word for using a compass?
When you are using a compass you are navigating to a certain point. So it could be navigation.
In which direction should the vessel's green sidelight be shining?
With your vessel's bow pointed at zero or 360 on your compass, the green light should be directed at 135 degrees.
What is compass for?
Finding North or relative position to North. There is a circle-making device also known as a compass.
How would you determine whether the risk of collision exist between your vessel and another vessel?
The standard answer is constant bearing. As soon as a another vessel is sighted at sea, you take a compass bearing on it, and you keep on taking compass bearings. If the bearing does not change, you are on a collision course. If it's on your port side, do nothing. If it's on your starboard side, give way by changing speed or course.
Why might an inexperienced explorer get lost using a compass?
by looking at the compass the wrong way or maybe using it wrong
What compass is use for?
Finding North or relative position to North. There is a circle-making device also known as a compass.
What is the purpose of a boat compass?
The needle on a compass always points true north. In marine use, a compass can be used to adjust the path of a vessel so it stays on course. A compass can also help one detour from a charted course in order to avoid a storm or other hazard.
HOW TO Transfer a position circle in chart work?
In transferring position you should measure your position or locate your position then bring it to the compass rose in order to get your position.
