How can this be done?

If your starting position is known, one of those inertial gyroscope thingies
might work.

Joe you seem to be rather thick, you must take this post in the context of the
others that preceded it. If you do so you will be aware that there is in fact
"external" input; The examiner is going to tell you your starting position, compass
heading and any course changes, most likely you will also get the boat speed through
the water. You have to plot your course accounting for set, leeway (you are going to
have to know your boats characteristics for this based on angle of heel, something you
can sense in the cabin and therefore another input), drift...., you will have a watch and tide
tables.

To accomplish this with some accuracy is not that difficult, I'm not sure
why you seem to be so astounded by such an ability.

Joe, you obviously think that I would mislead you. Let me take this
opportunity to reassure you that I would never give you false information.

Take a look at any of these links, and search for "blind navigation".

http://www.southern.co.uk/courses.htm

http://www.capitalsailing.com/pc_ym.html

http://www.hamble.co.uk/yashtmaster_prep_motor.htm


By the way, there is a web site called www.googol.com which you can use to
find out things for yourself.

Joe, read the thread that you copied that text from. Try about two posts
down.

Maybe you need to go on an RYA course, where they will open your eyes to the
science of blind navigation.

Thats not what his post said thicker thick thickest, he said no imup
exterinal imput.

The examiner is going to tell you your starting position,

Yes external imput # 1


compass

External imput #2


and any course changes,

External imput #3

most likely you will also get the boat speed through
the water.

Tide tables?

EXTERNAL #5

leeway (you are going to
have to know your boats characteristics

for this based on angle of heel, something you

Ill say that internal and OK with what the yachtmaster wannabe claims.
After all you can sence that in a pilot house with the windows blacked
as stated.

No Joe, that is not what I am saying, if you want to pick and choose
bits and pieces rather than the whole, then you will be able to find
cause for a fight.

Poor, Joe! Poor, poor Joe.

As you are in a Yachtmaster exam, you will already know your position.

You certainly do not need to be told your position at the start of the blind
test, as at that point you were not navigating blindly.




compass
heading

External imput #2

Poor, Joe! Poor, poor Joe.

I'm almost beginning to feel sorry for you.

You do not ask the crew for the compass reading. As the navigator you
*tell* the crew what the compass heading should be.

It quite simple, isn't it? ... .... well, OK, you'll just have to take my
word. It *is* simple. Honestly.





and any course changes,

External imput #3

If I am navigator, then I direct the course changes.



....... go on Joe, you really want to mention "meeting" or "crossing"
situations, don't you?




most likely you will also get the boat speed through
the water.

EXTERNAL imput #4
You have to plot your course accounting for set,

A competent navigator will have used his tide tables before he sets out on
his trip. In fact, I mentioned this a couple of years ago. I always insist
that my wife and my sons do independent passage plans before a long passage
so that they will really *know* where we are if something happens to me.



Tide tables?

Yes! Navigators use them when their GPS sets break down.

Joe, by this stage you should be beginning to realise that I can make more
sense while talking out of my arse than you can by utilising all the
intellectual abilities that you have at your disposal. [good insult, huh?]

In all honesty, Donal, you've made little sense, just beat about the
bush as if you hold the secret to life.
The simple question posed was: What information, inputs, aids, were
available to the person taking this test?
Feel free to list them, numerically .... ya know ..... 1., 2., 3., etc.,
then everyone can decide how difficult or not, it is.
In the past, many people used many methods to do some highly accurate
"piloting", and many of these practices have been lost or never learned,
by most of the newer "navigators".
I, for one, would be interested in the specifics of this test, but from
your description, don't have a clue as to what's involved, though I'm
beginning to pick up some glimmers, that it's a basic piloting exam.
Simply stated, give Ole Joe some basic info to work with and maybe he'll
stop asking questions ..... or is this a troll ?
