If you've got a 30mph side wind and you're doing 30mph ground speed, then
the resultant wind vector - the wind you actually feel - is 45mph at 45deg.
Double your speed, still with a 30mph side wind, and you have a 70mph wind,
but hitting you at less than 30deg off the straight ahead. Go up to 90, and
you get a 95mph wind at only 20 deg. If the wind gusts up to, say, 45mph,
then at 90mph you get a 5mph increase in wind speed and maybe a 6deg change
in direction. If you caught that gust at 30mph, then your wind speed would
go from 45mph to nearly 55mph, and you'd also have an 11deg change in wind
direction to cope with.

If you want to play around with wind vectors, try this site:

http://comp.uark.edu/~jgeabana/java/VectorCalc.html

If you need something portable to use while crossing the Severn - or
sheltering at Aust, waiting for the wind to drop - get one of these:

Heh. Last time I has a conversation about "real" and "apparent" wind, it
was on a 36 footer bobbing about in the oggin. It was ended by the guy
on the helm "venting" the previous night's curry with a cry of "Now
*that's* what you call apparent wind! Wahey!"

I think he means the one with the incredible croos-winds.

Following *anyone* was fairly likely to put you in a ditch.

I was on that one and I followed Andy. I have to admit it was somewhat
scary in the crosswind but we got there and had time for at least 3
fags before anyone caught up.

That was fun.

During a huge system outage earlier last year I did 4 back to back 19.5
hour days over a bank holiday weekend. Somehow I found it almost
impossible to sleep between then..

My comment on day 3 was that it was like being drunk but without any
kind of hangover.

I find I'm good for up to 3 days if required, so long as it's without
*any* sleep; nodding off, even for a couple of hours, seems to ****
everything up badly.

I did that during some enormous NMS upgrades for Global Crossing. A
day before the scheduled start, they asked for it to be done 48 hours
sooner. I did 124 work hours that week.

The faster you go the further to the rear the centre of the 'effective
sail area' becomes. As this gets further behind the centre of gravity so
the more stable you become.

The Black Pig?

I can think of a helicopter, a frigate and Capt. Pugwash's boat but
they're not fast enough to have a 5 foot shift.

Is it the same as The Black Banana?
