Safety information
Passage making under autopilot control is an enjoyable experience that
can, if you are not careful, lead to the relaxation of the permanent
watch. A permanent watch MUST be maintained no matter how clear
the sea may appear to be.
Remember, a large ship can travel two miles in five minutes – just the
time it takes to make a cup of coffee.
The following rules should always be observed:
• Maintain a permanent watch and regularly check all around for other
vessels and obstacles to navigation – no matter how clear the sea
may appear a dangerous situation can develop rapidly.
• Maintain an accurate record of the vessel’s position either by use of
a radio navigation receiver or visual bearings.
• Maintain a continuous plot of position on a current chart. Ensure the
locked autopilot heading steers you clear of all obstacles. Make
proper allowance for Tidal Set – the autopilot cannot!
• Even when your autopilot is locked onto the desired Track using a
radio navigation receiver, always maintain a log and make regular
positional plots. Radio navigation signals can produce significant
errors under some circumstances and the autopilot cannot detect this
situation.
• Make sure that all members of crew are familiar with the procedures
to disengage the autopilot.
Your Raytheon autopilot will add a new dimension to your boating
enjoyment. However, it is the responsibility of the skipper to ensure the
safety of the vessel at all times by careful observance of these basic
rules.
