Definition
The tripping line is made fast to the crown or dedicated trip eye and buoyed at the surface, its length slightly exceeding the maximum expected depth so the buoy does not pull the anchor out at high water. It marks the anchor's position for other craft and allows recovery in the reverse direction if the flukes are hooked. In strong streams it can foul propellers, so it is often streamed only where the bottom is known to be foul.
