Direct Reading of Heading on the Compass Bridge
Remove the hood. Read the heading at the ahead lubber mark of the compass.
The second, aft orientated, lubber mark is for officer´s inspection. Add 180° correction to get the ship´s heading.
Removing/Attaching of Binnacle Hood
Take hood with both hands
Loosen two knurled knobs
Turn hood and lift
When closing the binnacle secure
carefully the hood by fixing the
knurled knob!
Maintenance: Guiding surface of hood should be lubricated from time to time.
Taking Bearings
A vane type azimuth device is included in the standard range of delivery and will be found in a wooden box.
Also included is a shadow pin.
Remove the binnacle hood to set up the azimuth device onto the centre pivot of the upper compass cover glass.
Open object (wire) sight vane and ocular (slit) sight vane. Use the circular peep in the ocular (slit) sight vane for
a rough pick-up of the bearing mark. For accurate bearing use the slit of the ocular sight-vane.
Compass bearing (azimuth) of land marks up to 30° of elevation:
Read the compass card as illustrated below.
Relative bearing of land marks up to 30° of elevation:
Read the divided verge ring at the index of the ocular sight-vane. The scale ring is marked all-round. If semi-
circular bearings are required subtract 360° from the all-round value for objects port side of the vessel. The
starboard bearings remain unchanged.
Sun or star azimuth by azimuth mirror:
The black mirror at the object sight-vane can be hinged up and down according to the star height. The darkness
is suitable to allow sun observations (before make sure that sun will not dazzle!). Read the bearing as required
at the divided verge ring of the compass or at the compass card. Make sure that the compass is horizontal
balanced. It is not recommended to take bearings of astronomical objects higher than 45° because each
accidental inclination of the compass will distort the measurement.
