The Anchor Kit can be deployed on a Boat. The Anchor can then be lowered to prevent the Boat from drifting, or be raised to allow it to move again. The time it takes for the Anchor to rise depends on the depth of the Ocean: 2 seconds on Coastal Ocean and Brine Shoals, 6 seconds on Swell Ocean, 8 seconds in Rough Ocean and 10 seconds in Hazardous Ocean. The time it takes for it to lower is a third of the raising time.
If an Anchor is hammered, it will leave a boat leak in its place.
