In other words, you have to sail (and navigate) the boat "blind".

No external imput at all.

How can this be done?

Joe you seem to be rather thick, you must take this post in the context
of the
others that preceded it.

Yeh right show me this content.

If you do so you will be aware that there is in fact
"external" input;

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

Poor, Joe! Poor, poor Joe.

As you are in a Yachtmaster exam, you will already know your position.
With the pilot house windows blacked out the only way your going to
know your position is someone tells you. Understand? Thats external
imput, comprende?


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.

Oh OK, that makes sence. When I learned to navigate we needed to know
were we were, that was some of the basic stuff.




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.

But you have to look at the compass to tell what your course is,
therefore the compass is giving you imput, can you understand this
farout concept?

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

Simple imput a CC






and any course changes,

External imput #3

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

Not if you move blind into a strong current, the current might set
your course and drift, without external imput from your compass you
will not be able to accurately tell your deviation from orignal
heading, if you are blind that is.



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

Yeah and being blind without external imput meeting situation are
going to be very risky huh?





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

well thats more external imput isnt it?


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.


They do! Wow your smart.



EXTERNAL #5

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),

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.

drift...., you will have a watch and tide
tables.

Yelp EXTERNAL IMPUT #5


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.


Damn..... With 5 external imputs that as easy as tieing your shoe. I
thought these yachtmasters knew something special and astonishing.

I other works Lanod was talking out his arse and did not have a clue
what he was saying. Is that what you are saying ?

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?]

About as good as your description of blind navigation with no imput at
all, you know the "Waves slapping on the hull" line you spewed. Your
yachtmaster exam sounds like what a basic OS or AB would sit for.
Basic Basic Basic. Your the only one that thinks it is , difficult,
mysterious, and a great feat of navigation.

If you lived in the early 1800's you be yelling at the skipper STOP
STOP before we fall off the edge of the world.
