Most of us have seen the short video clip - I came across another link for
it today - but does anyone know the story behind it? Was the guy who fell in the water OK? How much damage to the smaller vessel? Surely an anchor is never intentionally dropped that quickly? Charles ==== Charles T. Low - remove "UN" www.boatdocking.com www.ctlow.ca/Trojan26 - my boat ==== |

I think I remember seeing the picture you are referring to.. I don't
remember the whole story.. However, the standard procedure for "dropping the anchor" is just that. I spent many a cold and dreary hour or so on the anchor detail of several US Navy ships.. The anchor chain is held fast by a pelican hook and the anchor windlass brake. The procedure is to insure that the pelican hook is in place with the safety pin holding it closed, disengage the anchor windlass motor from the 'wildcat' or gypsy, all hands stand clear of the chain. Then upon direction from the officer of the deck (OOD), on the bridge, to drop (release or let go) the anchor, the seaman with a sledge hammer pulls the safety pin lanyard from the pelican hook and knocks the latch off the pelican hook. The anchor drops and the chain rattles out of the 'chain pipe', over the deck and down the 'howse pipe'. The person in charge of the forecastle detail will count markings and report the amount of chain that has been released. He can also tell when the anchor has reached bottom and will report this. The brakeman will begin slowing the chain with the hand brake on the 'wildcat'. Once the chain is under control, the ship will back down while the brakeman lets out more chain until the OOD is satified there is enough scope and the anchor is set. Scope is then adjusted by either letting out more chain or by engaging the windlass motor and hauling in chain. You might wonder why the anchor is dropped rather than lowered, under control.. The windlass motor is gears so low that it would take more than a few minutes to reach bottom and if you lower it 'on the brake', it would over heat and burn up in short order. It is important to get the anchor to the bottom quickly, while the ship is in the desired position. Ships have 'dropped anchor' for hundreds of years and most private boats do the same. Oh! Yah! Maybe someone should look over the bow to see if some work boat is under the bow. Not in the SOP (standard operating procedure), but worth while considering.. -- My opinion and experience.

Not sure of the reason for the letting go of the anchor (accidental or
intentional) but, luckily, no one was injured (the guy overboard was quickly retrieved) and damage to the boat, was supposedly minimal. Normal procedure on a merchant ship, is to have the anchor on the brake, when preparing to let go. The wildcat will be disengaged; riding pawl, flipped out of the way; and pelican hook or wire stoppers removed ..... simply release the brake and let it go. Depending on depth and whether the ship is slightly moving astern (preferably), the chain will stop running on it's own, or may have to be stopped with the brake (hate runaways). otn Charles T.

Subject: ship anchor hitting smaller vessel
From: "Steve" Date: 11/02/2003 08:41 Pacific Standard Time Message-id: I think I remember seeing the picture you are referring to.. I don't remember the whole story.. snip Navy warships tend to use a vertical capstan for their anchor windlass, whereas most commercial vessels use a horizontal winch/windlass, which means the details may vary, but overall, the same. One of the test during seatrials is to be in deep water, and do a controlled drop of the anchor, on the brake, to it's full length (hanging free in water .... @ 11 shots or roughly 1,000 feet of chain and anchor hanging below the ship ..... then heave it all in, keeping fingers crossed).

It involved at least 8 people. There was one guy with the sledge hammer to knock the paw loose. Another manning the brake. One guy who I think was counting the markers on the chain. One guy to call out the response to the command, and another guy who's job appeared to be to repeat everything the first guy said, another guy with a headset on that I would assume was talking to the bridge, and a couple more that just seemed to be watching. All very precise and by the book. And no, I don't recall anyone looking over the side to make sure it was clear below. I also watched a cruise ship drop anchor. They did it with two people on deck. I don't recall them looking over the side either. Rod McInnis |

Normal on a merchant, is two people .... in a emergency, one.
Looking first, is a highly abused step in the letgo procedure. otn Rod McInnis wrote: "garry crothers" wrote in message ... So how many people are talking about here to drop this anchor?????

CG boats always have a person on watch (remember your 'navrules'), so would be aware if there was a boat in the area..at least that's the way the rules are supposed to work --------------------------- to see who "wf3h" is, go to "qrz.com" and enter 'wf3h' in the field |
