You never did tell anyone how you yachtmasters navigate without
any
aids or inputs. Remember the wave slapping on the hull **** you
spewed?

I thought that I wouldn't need to explain the basics of navigation
here.

Yachtmasters only have to show that they can navigate without
external
inputs to prove that they understand the basic principles of
navigation.


Tell us O yachtmaster, How do you navigate without external input?

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.

HEY DONAL A WAKE IS EXTERNAL INPUT!!!!!!!!!!!!


YES, JOE. THAT'S WHY I CALLED IT AN EXTERNAL INDICATOR!

Sheesh! This is hard work [ wipes perspiration off brow]




I will have to use predictive skills to
determine my position.

BUY SEEING THE SET OF YOUR WAKE? THATS EXTERNAL!!!!

I KNOW! THAT IS WHY I CALLED IT **EXTERNAL**.

[wipes more perspitarion off brow]





On a 70 mile trip, I will be accurate to within one
mile.





BECAUSE OF EXTERNAL IMPUT YOU GOT BY SEEING YOUR WAKE AND MAKING
CORRECTIONS USING YOUR COMPASS COURSE, WHICH IS EXTERNAL IMPUT, unless
your on a bent a toe and the wake is in the bildge.

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
crossing,
as I have no experience of such things.


Thats mighty humble coming from a yachtmaster wanna be.

Humility is an important characteristic in a Yachtmaster! Maybe you should
do the course??


Now tell us how your going to be in the blind with no external imput
and navigate O yachtmaster.

Tsk, tsk. You're beginning to twist my words.



Regards


Donal
