ST1000 Plus & ST2000 Plus Tiller Pilots
Confirming position at the start of a journey
• At the start of a journey you must always use an easily identifiable fixed object
to confirm the fix given by the navigation system.
• Check for fixed positional errors and compensate for them.
Verifying computed positions
• Always verify the computed position with a dead reckoned position, calcu-
lated from the average course steered and the distance logged.
Plot frequency
• In open water, you should make plots at least every hour.
• In confined waters or when near to potential hazards, you should make plots
more frequently.
Setting waypoints
• Local variations in radio signal quality and changes in the tidal stream can
produce deviations from the desired track. When setting waypoints, remem-
ber that deviations can occur.
• Thoroughly check along each track. Check up to 0.5 nm each side of the track
to ensure that there are no hazards within this zone.
• For the waypoint advance function to work, the last four characters of adja-
cent waypoint names must be different.
