No lubrication required on account of simple mechanism. Every watch the officer is to check whether the correct course is being recorded & pens are full of ink. Course recorder clock always to be set on GMT. To be switched off in port. Date, time & place important.
Once set, the course recorder records the Gyro course steered on a specially designed paper throughout the voyage. The recording paper is a specially formatted thermal paper hence an inkless stylus is used to mark the course steered,
Another option for reducing yaw and solving another problem at the same time would be an arch right aft with solar panels on it, although given that it will not be wing shaped as a bimini is, I suspect it won’t be as effective. And, indeed, I have seen plenty of boats with arches still surging around.
The course being steered can be read by simply checking where the zone pen is (for example 180-270). Then we use that scale on the course section of the paper to read the course being steered as indicated by the course pen.
Anchor chain direction The direction of the chain is measured in two different ways: Clock format – The bow of the vessel (facing forward) is 12 o'clock, the extension of your arms is 3 o'clock and 9 o'clock accordingly, and the tail of the ship is 6 o'clock.
Swinging circle of the ship If the ship goes out of the swinging circle, the ship's anchor is dragging. Compare this with a cow tethered to a post. The cow can only swing on a circle with radius equal to the length of the rope she is tied to. She can only go out of this circle when the rope has left the post.
Chain lying on the bottom will prevent yawing, which in turn will improve holding.
Approach the anchor position heading into wind and tide with speed around 2 knots at 0.5NM from the position.Lower the anchor with gear to around half shackle off the bottom and then hold the anchor on brake.Give Stern movement to stop the vessel over the ground once the vessel is in the anchoring position.More items...•

override the anchor. If dragging is inevitable, let the vessel drag in a controlled manner.
Note : Centre of swinging circle is the point where anchor fluke touches SEABED.

Next we need to understand why boats yaw back and forth on their ground tackle, before we can decide what to do about it. Yeah, I know, you just want me to share some magic fix and screw the boring theory. Sorry, not doing that.
So now we understand the why of it, it becomes obvious that there are only two ways to fix the problem:
Morgan’s Cloud stripped for a late fall blow at Great Salt Pond, Block Island. Note that both headsails are off. The tightly lashed mainsail seems to help by moving the CE aft, so it stays. The dinghy was still to be stowed below when this was taken.
Some years ago, Phyllis and I were visiting Vardø, a small harbour on the north coast of Norway protected from the rage of the Barents Sea by a stone breakwater—probably one of the windiest places anywhere. Sitting serenely on a mooring was a Hallberg Rassy 38 sporting a small riding sail on the backstay.
So why don’t we use a riding sail on Morgan’s Cloud? Some years ago, we were seriously considering getting one when my dermatologist came up with another idea.
As I said from the start, clearly it’s easier to move the centre of effort aft than the centre of lateral resistance forward. But our own Colin Speedie has come up with a technique, using a small drogue attached to the chain, that you may wish to try. See Further Reading.
One more thing before we leave the subject. I’m sure it has struck many of you, while looking at the second diagram (plan), that if we could stop the bow moving around that would also solve the problem. And, in fact, it does.
Finding out how to read music is such a different skill from actually playing the recorder. As an element of our ‘Beginner’s Guide To Learning The Recorder’ range, this section will provide you with sufficient information and facts to get started practicing this amazing skill.
For recorder, staff notation is actually organised around something named the treble staff. This consists of a stave (the name for the lines) of 5 lines and 4 spaces. It is usually labelled with a treble clef (the squiggly thing at the beginning of the line)!
To prevent counting up from middle C each and every time, you can take advantage of memory aids to recognise the notes. The four spaces in the treble staff spell out “FACE”.
Researchers at the Yerkes National Primate Research Centre, at Emory University, set out to understand why yawning is contagious.
Yawning was definitely catchy. But yawn catching only happened within “the family”.
As humans we share many biological behavioural traits with chimps so …. it seems logical to extrapolate the Emory chimp findings to our own situation.
So how can your lecturer/teacher or boss, feel upset at the odd yawn during a presentation.
