"Lay a course" is a nautical term that refers to the action of determining and setting the direction in which a vessel should travel. The phrase is commonly used in marine navigation and sailing to establish a planned path or route to be followed by a ship or boat.
When a navigator or sailor decides to "lay a course," it means that they are plotting the desired direction that the vessel should take to reach its intended destination. This process involves considering factors such as wind direction, speed, currents, navigational aids, and any obstacles or hazards that may be present in the water.
To lay a course, navigational charts and maps are often consulted, taking into account the vessel's size, speed, and maneuverability. The course is typically determined by drawing a line on the chart connecting the vessel's current position with the intended destination.
Once a course is laid, it serves as a guide for the helmsperson to steer the ship or boat along the planned path. Adjustments and corrections may be made along the way to account for changing conditions, but the laid course provides a fundamental route to follow.
In summary, "lay a course" refers to the act of planning and setting the desired direction for a vessel's movement, ensuring safe and efficient navigation towards a specific destination.
