Study Notes

Course Recorder Overview

Installed on the bridge to record gyro courses during the voyage.
Utilizes a built-in timer, typically a winding clock, to timestamp records accurately.
Essential for providing evidence in accident or collision cases.
Must be correctly set prior to departure and ensure proper recording.

Inputs to the Course Recorder

Gyro Compass Connection: One repeater linked to the course recorder manages signals for the spiral grooved drum, controlling the movement of the course stylus.
Clock Functionality: Connected to the paper feed roller, this clock regulates the speed at which paper moves under the stylus, ensuring alignment with time graduations.

Stylus and Recording Paper

Stylus Types:
- Older models use ink pens requiring weekly refilling with slow-drying ink.
- Modern course recorders like Anschutz utilize conductive wires that mark the paper directly upon contact with the metal plate.
Paper Specifications: Supplied in rolls, installed following manufacturer’s guidelines, and typically feeds vertically from top to bottom.
Graph Paper Design:
- Time Scale: Located on the left side, permits setting correct GMT (though practices may vary).
- Course Section: Positioned centrally, marked in quadrants for detailed course reading, allows measurement to the nearest degree.
- Zone Section: Found on the right side, consists of four columns to clarify quadrant identification, helping to prevent ambiguity in course recording.
