Our grandfathers in the Navy had so their own manner of anchoring. What they did was to steam with the tide and or wind, whichever was stronger, put the helm hard over and just as the ship started to swing, let go the cable on the run on the inside of the turn. Then they ran out to the required leng…

The navy, everybody’s navy, seems to do things that are really hard on the equipment. Letting the anchor and chain snub up the moving ship would certainly give you a result quickly. Some kind of result. I imagine a burned brake band, or even mis-adjusted brake band would quickly leave all of your…

[image] Anchored Vessels Behavior in Wind They they ran out to the required length, set the stopper and allowed the anchor and cable to snub the ship round into the weather. Not as bad as it sounds because the anchor gear is being used to turn the ship, the force will be more or less at right …

It’s still putting unnecessary stress on the ground tackle and brakes, etc…

Anchoring downwind is a good way to do it. You can work up to it. A car ship moves relatively fast sideways in the wind. In about 15 or 20 kts of wind the ship can be stopped with the wind abeam and upwind of the desired spot, when the ship drifts over drop an anchor under foot, ship will turn up w…

The usual way to anchor a ship is to stop the ship and put the engine astern. Then the anchor is walked out to just above the bottom, after which it is let go or walked out until the required length of cable is on the bottom. Your anchoring scheme is much more sophisticated and is a variant of the …

In the standard method the speed and heading of the ship must be tightly controlled, car ships in the wind don’t like that. Instead this way only the downwind motion of a single point on the ship has to be controlled, the point at the hawsepipe. If the wind is at 90 degrees, from 90 to 30 degrees …

Here is a diagram, much simpler than my text.Start anywhere above the blue line. Red circle is anchor position. The black wavy line is the anchor chain being laid out. Final position is anywhere on the red line. Not much precision needed, wind does the work. [image] The above is the passive meth…

Here is downwind anchoring. In the second position if anchor spot is marked on the radar (or ECDIS) the ship true vector can be adjusted with the engine alone, here just a little stern way is needed to hit the spot. The radar vector will show when it’s right. [image] First position should be a b…

Probably has to do with looking smart and snappy. Their schedule is flexible and tax payers are paying the bills so what the hell; "Full speed ahead and damn the torpedoes" is more fun than a slow and methodical approach.
