10.3.6.4.9 Anchor Watch Alert

The Anchor Watch Alert is very similar to the Outside Radius Alert, being tailored

to anchoring. It is used to signal an alert whenever the vessel moves a

programmable distance in any direction away from an anchor point (expressed

as a longitude and latitude). This alert is useful when the vessel is anchored or

moored and the vessel should not drift outside a perimeter and if it does, an alert

is activated. The point of reference can be selected from the current position or it

can be manually entered, or it may be entered by pressing a button on the

Anchor Watch Component (see section 9.5.2).

10.3.6.4.9.1 Instancing – Anchor Watch Alert

When editing an Anchor Watch Alert, the instance number of the GPS supplying

the vessel’s position must be specified.

10.3.6.4.9.2 Trigger Configuration – Anchor Watch Alert

While the units of the radius for the Outside Radius Alert are expressed in the

same units as distance (e.g. Nautical Miles), the units of the Anchor Watch Alert

are expressed in the same units as the depth (e.g. feet). This is more convenient

because the distance from the anchor will be related to amount of anchor chain

released, which in turn is related to the depth at the point of anchor.
