Rode and scope — pick a length you will trust
Understand scope, and set the drift radius the anchor watch alarms on.
Scope is the ratio of rode let out to the vertical distance from bow to bottom (water depth plus your bow height above the water). The common rule is 7:1 in weather, 5:1 in calm protected water, 3:1 only if you have to.
theONE never asks what your rode is made of, and there is nothing to type in. The Anchor Watch sheet holds one setting — a Drift radius — and theONE works it out from the rode your windlass reports, the depth, your draft and your length overall, or starts at a flat default when it cannot.
If the boat moves further from where you armed than that radius, the chip turns to ANCHOR DRAGGING and theONE alerts you.
Steps
-
Drop the hook and let out rode
Set the anchor as you normally would. There is nothing to type in later — theONE takes the rode figure from your Windlass reading — so note what you let out only to check the radius against it.
-
Open Anchor Watch
The Anchor Watch chip sits at the top of Mission Control's telemetry widget. Tap it.
-
Set the drift radius
There is no rode field and no rode-type field. The sheet has one setting, a Drift radius slider, and theONE seeds it for you when your windlass reports rode out and there is a depth reading: it works the radius from that rode, the depth, your draft and your length overall. Without both of those it starts at a flat default. Read the radius, move the slider if it looks wrong for where you are lying, then Arm at current position.
-
Once it is armed
Once it is armed the chip reads Anchor watch with the radius beside it. If the boat moves further than that from where you armed, it turns to ANCHOR DRAGGING and theONE alerts you. Clear anchor watch, in the sheet, stops it.
