Rap full means a little off the wind, with all sails filled, and to
have a flaw is to have a gust stronger than the prevailing wind.

Can you reeve and jump a cod line? And if you can, what are you doing with what?


Yes you can reeve and jump a cod line. To reeve a line means to pass a
line through a block, and to Jump a line is stand at the mast and pull
down on a halyard as another crewmate winches it in. And a Cod line is
according to "The Oxford Companion To Ships And The Sea", a codline is
a: Small line laid up with eighteen threads. It was originally the
line used in fishing for cod, but also has a variety of uses on board
ship for purposes where small rope would be too large and clumsy.



Have you ever seen a kumatage?

Guess Jonathan is the only one to see or know what he saw. A Kumatage
is a bright appearance in the horizon, under the sun or moon, arising
from the reflected light of those bodies from the small rippling waves
on the surface of the water FROM Bowditch´s Navigator, 24th edition
(1854) page 295,




Why are those Navy coats called Pea coats?


again Johnathan knew the correct answer. The heavy topcoat worn in
cold, miserable weather by seafaring men was once tailored from pilot
cloth, a heavy, course, stout kind of twilled blue cloth with the nap
on one side. The cloth was sometimes called P-cloth for the initial
letter of "pilot" and the garment made from it was called a p-jacket,
later, a pea coat. The term has been used since 1723 to denote coats
made from that cloth.

Whats it mean to scud.


no one knew that to scud is to run before a gale with little or no
sail set.... Also.... a gust of wind. Ragged low clouds, moving

I wish I had been paying attention - I didn't notice this question.

There's an old saying around Portsmouth and Cape Ann: In the event of a

Joe, you make me see red!

Yes, you guessed correctly! I'm only talking about your neck!


Please read my previous post again ... and this time try to understand it.

The "blind" test is done to establish the student's ability to predict a
boat's track from data such as tide tables, wind speed and direction, and
knowledge of a boat's performance.

For example, when I cross the channel, I will usually be out of sight of
land for many hours. If I am using trad nav, then I will only have the
wake as an external indicator. I will have to use predictive skills to
determine my position. On a 70 mile trip, I will be accurate to within one
mile.

I accept that this accuracy might be different on a trans-Atlantic crossing,
as I have no experience of such things.

Oh, good. All that shouting was tiring me out, and I do think that your
face turned quite red, too.

Joe, I was pointing out that sailors have been sailing with very little
external input for a very long time.
It is possible to sail with a fair degree of accuracy without much in the
way of inputs. Little over a generation ago, many people would cross the
channel (60 - 70 miles) with no instruments at all, apart from a rudimentary
compass.
You seem to have a problem understanding this. I can't understand how
anybody, with even a rudimentary amount of navigational training, cannot
grasp the fact that it is possible to plan a course, and sail to it, and
arrive at one's destination using a chart, tide tables, compass, watch and a
pencil.


I accept that this accuracy might be different on a trans-Atlantic

I've been wait for you to describe what you meant by "no external inputs."
Clearly, if you had no inputs, (and no inertial guidance system) it would be
difficulty indeed to deduce where you were. And if all you meant was no GPS,
then the discussion is almost as meaningless.

But you claim in your previous post 1 mile accuracy for a 70 mile trip, crossing
a channel the has (I think) a current of several knots. Is this really
feasible? This implies a distance accuracy of about 1.5 %, which thus implies a
speed accuracy of about 0.1 knots. I doubt there's anyone here that would claim
to be able to "eyeball" a boat's speed with anywhere near this accuracy. I'm
not sure I could reliably calibrate my log this well, and I certainly wouldn't
trust it a day later.

And the course accuracy? That's better than 1 degree. Again, I know I can't
hold a course that well over time, but I would also argue that most compasses
aren't that accurate to start with. In fact, there are some locations where the
variation isn't that stable either.

And can anyone give the leeway figures for their boat that accurately? If the
wind is variable can you integrate the net affects over time? And how accurate
does one know the current? Even if you adjust for the state of the tide and the
phase of the moon, can you predict the current to 0.1 knot?

Can one argue that many errors are possible but they tend to cancel out? Nope,
it doesn't work that way; although there will likely be some canceling.

No, I can't buy your claim of 1 mile accuracy in a 70 mile trip, with only a
compass; I doubt you ever did it, and you certainly couldn't do it reliably.

Its certainly true that there were many, many coastal passages 100 years ago,
and I'm not going to claim that the accident rate was infinitely higher back
then. (It was, but that's not important.) But they did have other tools that
we tend to forget about: Lighthouses, fog horn, lead lines etc. They weren't
quite as blind as you're making them out to be.

BTW, I have done the experiment of sailing "blind" a number of times. I served
as a guide for a blind sailor a number of times, so I tried it out to see what
it was like. I refined it into a "parlor trick" for my students, where I would
lie in the bottom of the boat while they sailed about a mile around the river
basin. I could tell them where we were to within a 100 yards or so. The was
that because I had sailed this one square mile almost exclusively for 15 years,
I could locate myself any time by a number of cues, such as the traffic noise
from shore, or the wind patterns from buildings, or the different sounds of the
boats from different clubs. Like I said, a parlor trick. But someone who
crossed the Channel daily all their life would have the same ability.

channel (60 - 70 miles) with no instruments at all, apart from a

rudimentary
compass.


I've been wait for you to describe what you meant by "no external inputs."
Clearly, if you had no inputs, (and no inertial guidance system) it would

be
difficulty indeed to deduce where you were. And if all you meant was no

GPS,
then the discussion is almost as meaningless.

But you claim in your previous post 1 mile accuracy for a 70 mile trip,

crossing
a channel the has (I think) a current of several knots. Is this really
feasible? This implies a distance accuracy of about 1.5 %, which thus

implies a
speed accuracy of about 0.1 knots. I doubt there's anyone here that would

claim
to be able to "eyeball" a boat's speed with anywhere near this accuracy.

I'm
not sure I could reliably calibrate my log this well, and I certainly

wouldn't
trust it a day later.

And the course accuracy? That's better than 1 degree. Again, I know I

can't
hold a course that well over time, but I would also argue that most

compasses
aren't that accurate to start with. In fact, there are some locations

where the
variation isn't that stable either.

And can anyone give the leeway figures for their boat that accurately? If

the
wind is variable can you integrate the net affects over time? And how

accurate
does one know the current? Even if you adjust for the state of the tide

and the
phase of the moon, can you predict the current to 0.1 knot?

Can one argue that many errors are possible but they tend to cancel out?

Nope,
it doesn't work that way; although there will likely be some canceling.

No, I can't buy your claim of 1 mile accuracy in a 70 mile trip, with only

a
compass; I doubt you ever did it, and you certainly couldn't do it

reliably.

Its certainly true that there were many, many coastal passages 100 years

ago,
and I'm not going to claim that the accident rate was infinitely higher

back
then. (It was, but that's not important.) But they did have other tools

that
we tend to forget about: Lighthouses, fog horn, lead lines etc. They

weren't
quite as blind as you're making them out to be.

BTW, I have done the experiment of sailing "blind" a number of times. I

served
as a guide for a blind sailor a number of times, so I tried it out to see

what
it was like. I refined it into a "parlor trick" for my students, where I

would
lie in the bottom of the boat while they sailed about a mile around the

river
basin. I could tell them where we were to within a 100 yards or so.

The was
that because I had sailed this one square mile almost exclusively for 15

years,
I could locate myself any time by a number of cues, such as the traffic

noise
from shore, or the wind patterns from buildings, or the different sounds

of the
boats from different clubs. Like I said, a parlor trick. But someone

who
crossed the Channel daily all their life would have the same ability.


Good questions, and I admit that I cannot give precise technical
explanations for the accuracy.


I will try to give as honest an answer as I can.

When I did the Yachtmaster Shorebased course(a classroom course), the
instructor told us that there "should be only one navigator" on any trip.

On the first Channel trip that I did I was surprised at the accuracy.

My second trip was in a charter boat. One of us was a RYA (coastal skipper)
instructor. He was a bit of a "know it all". On our return trip, a 23 hour
crossing from Guernsy to Salcombe, he woke up, looked at the Decca, and
ordered a 15 degree course change.

I asked if he wanted to take over the navigation ("there should be only one
navigator"). He declined.

He made me nervous enough to advise a 5 degree alteration to our course.
After all he *was* an instructor.

We hit land 5 miles **downtide** of our destination, and had 3 dreadful
hours of sailing into wind and tide. That night, I decided that I would
trust my own abilities in future. I'm not a great sailor, but I *am* good
at maths.


Where I cross the channel, the distance is about 60-70 miles. In fact, the
trip to Cherebourg is 74 miles, but I have to go to Bembridge Ledge buoy
first. From there, it it is 64 miles.


The trip time is about 12-14 hours. This fact has an impact on the
navigation. I tend to have 6 hours of ebb, and 6 hours of flood. Thus,
the tide will tend to push me as far one way, as it will the other.

Many people will check their position on the GPS when they are half way
across. If they are off course, then they assume that they were steering
the wrong course. I don't do this because it is more likely that the tidal
stream was not as predicted. If it came in faster than predicted, --- then
it will go out faster than predicted. People (like Joe), who react tend ti
over-correct.

Ok Bart r anyone

om...
No you said " Blacked out porthole with no external imput"

I agree it can be done very well with little imput.




At last!!! I assume that the arguement is over??
