Please tell us about your sailing ideas where a spinnaker is carried as

I thought you were talking about the Valsheda pic.


Well I even gave the sail number to make sure we were talking about the
same pic! Was that too hard for you to read?

In any event, 45 is a lot closer to 30 than it is to 20


..... Wind
pressure (and therefore potential power extractionon) on the sail must
proprotional to the sine of the heel while leeway will rise roughly with
the cosine. OK?


It seems to me that before you start to yabble about trig & calculus, you
should learn some basic math. 45 is definitely a lot closer to 30 than it is
to 20. Look it up.

Oh, now I can see the level of your maths ability. So you are not
interested in the behaviour of the boat but just want to say that 15 is
less than 25? If you had told me I was going to be talking to someone
with the maths ability of an 8 year old I would not have bothered
posting a detailed discussion on the basis of the relationship between
heel and VMG. If this is the case, then I apologise for posting
something so far above your education level that you think it double talk.


In any event, your posts have become a morass of insults and double talk.

Maths is is not double talk. It's precise and accurate and as for
insults, it's you that always starts it e.g. your last post.

There is no basic fact so obvious that you won't deny it to try and "prove"
that I am wrong. It's predictable and boring. If you are going to be a
caricature, you should at least try & be funny!


I though you claimed to be interesting in learning about sailing. I can
only surmise that this a lie because when I try to clarify your
misconceptions you become insulting and simply ignore what is said. Even
worse you then change what was said to suit your peculiar form of troll.
Why not try to engange your brain and think about what I wrote? I'd
enhjoy an intelligent conversation with you. Here, I'll post it again.
Read it. Is it wrong? Come to that, why did you bring up the number 45
anyway -was it only to make the irrelvant point that 45-30 30-20?
What could be the point of that in the context of discussing keel boat
_performance_?

Cheers
