True North
True North is the direction pointing towards the Earth's geographic North Pole. It is the direction along the Earth's surface towards the North Pole, where all the meridians meet. True North is a fixed point on the Earth's surface and is used as a reference point for navigation. It is different from Magnetic North, which is the direction towards the north magnetic pole and varies depending on the location and time. True North is used in navigation to determine the ship's position and course, and to calculate the difference between True North and Magnetic North, which is known as magnetic variation. This variation is important for accurate navigation and is taken into account when plotting a course.
