Chain & Warp = 6x depth of water.
Chain only = 4x depth of water.
Always take into account the 'swing zone' which can be impacted by wind or tide. Vessels move around their own swing zone at different rates according to their weight, freeboard and hull/keel
The anchor is connected to a ‘scope’ of chain, or a chain and rope combination. The amount of scope let out when anchoring depends on whether the scope is all chain or a mixture. The more scope you let out reduces the chances of the boat snatching the anchor out of the seabed. It also acts as a shock absorber.
If in a tidal area you need to allow for the rise of tide in your calculations. The amount of scope carried on board depends on your area of operation. In shallow estuaries 30m would be sufficient whereas in deep and rocky areas considerably more may be required.
The process of anchoring is very similar to picking up a mooring buoy. RIBs and speedboats with open bows are easier to anchor, because going forward is easy.
On larger craft with anchor lockers at the bow, a crew member must go onto the foredeck to anchor but with caution, keeping their centre of gravity low.
Yachts and powerboats move in different ways as the stream or wind changes. Check your anchor is not dragging by:
