About an help for a MsC about Emergency Anchoring

[Capt_Phoenix]

@BruceChun

An anchor will not generate the same amount of holding power when it was dragging. Its holding power is even less than those of a dragging chain. The 20mt mass in motion may provide a drag no more than 25 tonnes force with single anchor, 50 tonnes force with both anchors. It is no match to the momentum (100,000mt at 1m/s) of the ship even at very slow speed (2 knots).

You don’t want the anchor to hold in an emergency because it will part. You want it to drag on a short stay and slow the vessel down so you don’t hit anything.
