Setting up the anchor drag alarm

To set up the anchor drag alarm using the anchoring wizard, follow the steps below.

Note

Anchor mode can be configured with or without depth calculations. If you do not want anchor mode to include depth calculations, disable the Anchor alarm includes depth component option in the Advanced settings menu.

  1. Anchoring wizardSelect a suitable location to anchor your vessel.
  2. Select the ANCHOR mode icon from the chart app menu.
  3. If prompted, enter your Boat length and Bow to GPS distances and select OK.
  4. Select the Start anchoring wizard button located on the center of the screen.

    The first page of the anchoring wizard is displayed:

  5. Based on the initial Max swing radius shown in the live view pane, ensure the location is suitable and that no obstacle could come into contact with your vessel as it drifts.
  6. Steer your vessel into the wind / tide.
  7. If required, manually adjust the Depth and Chain length settings, using the relevant + and - buttons.

    • By default, the Depth value is the depth reading from the depth / sonar transducer (including any depth offset value configured for the transducer).

    • By default, the Chain length value is 4 times (4x) the water depth, plus one meter.

    Note

    Adjusting the Depth or Chain length values manually using the + and - buttons will fix their values. Depth will change to Anchor depth, and will no longer be updated by transducer depth readings . Chain length will no longer be updated when the Depth value changes.

  8. Lower your vessel’s anchor.
  9. AnchoringMark anchor positionOnce the anchor hits the bottom, select Mark anchor position.

    If required, the anchor position can be adjusted later using the onscreen controls.

  10. Deploy the remaining chain length while reversing / drifting with the wind / tide.
  11. AnchoringChain outSelect Chain out.

    The second page of the anchoring wizard is then displayed:

  12. Check that the anchor is secure. If conditions have changed, adjust the chain length or select Cancel (Raise anchor) and restart the anchoring process.
  13. Select Activate.
