Chapter 1: Operation

1.1 Getting started

This handbook describes how to operate, maintain and install the

Raymarine ST60 Wind instrument and ST60 Close Hauled Wind

instrument. These instruments show:

• Wind speeds and directions

• Velocity Made Good (VMG) information, when boat-speed

information is available,

• Tack angle, when heading information is available,

Calibration requirements

Your ST60 instrument is calibrated to factory (default) settings when

first installed and must therefore be calibrated before use, in

accordance with the procedures in Chapter 4, Calibration, to ensure

optimum performance on your vessel.

Do NOT use the instrument until the calibration procedures have

been satisfactorily completed.

If the CAL legend on the digital display flashes for the first 30 seconds

after any power up, use the appropriate procedures in Chapter 4,

Calibration to:

1. Apply the factory defaults.

2. Carry out the linearisation procedure.

Displayed information

The information on the ST60 Wind and ST60 Close Hauled Wind

instruments is presented in analogue form (pointer) and on a digital

display. This information can be either true or apparent, depending on

which mode is selected.

Pointer

The pointer shows the true or apparent wind direction. The scale range

given by the ST60 Wind instrument is a full 360

, whereas the ST60

Close Hauled Wind instrument gives an expanded indication from -

to +60

about the bow or stern of the boat.
