Remember too that the mast is a long lever... if you make a millimeter
adjustment at deck level, the top of the mast will move a lot further.
I think this is why so many people overdo it.


Holy leaping toads!

Yes. I agree.

Not only do you consistently fail to engage in any sailing discussions, but
you now feel that you must deride the efforts of people who actually make a
real contribution!!

The really strange thing is that you are reduced to Bush- like sentences
when you have one of your sneers.


I found Doug's post quite informative, and I appreciated the effort that he
put into making it easy to understand. Perhaps you found it a bit
difficult, and reacted by hitting out????

Hey Donal, can you adjust your mast in it's partners -or is it through
bolted?

Sorry, that was too complicated for me.

Can you put the question in terms that I can understand?

You know where the mast goes through the deck? Is it fixed in the metal
ring perhaps with a big bolt? It's just that if you were interested in
altering rake my adjustments at deck level it would be impossible with a
bolted partner... Instead you would have to alter rake at the mast foot
and that is also impossible on many boats as the foot casing is welded
or bonded to a ring frame.

I don't believe, not for a second, that Donal did not know what you were
talking about.
Nice of you to explain anyway for him.

And there was me thinking he was asking for information, espectailly as
he seemed taken with Doug's ideas about how the mast is a lever
amplifing deck level movements. Then again, do you suppose it could be
possible that that Dinghy Doug doesn't know that that bigger yachts with
keel stepped masts do not generally adjust rake at deck level?

I think that there are wooden chocks holding it in a vertical position.

Underneath the mast, there is a metal plate (SS or ally??) with two vertical
plates welded to it. These verticals are either side of the mast, and a
bolt goes through the lot.

Have you seen many keelboats with masts fixed by a thru-bolt at the partners?
This is not a very common arrangement at all over here. In fact I haven't ever
seen one.

Donal it apears that if you were interested in changing the rake of your mast,
or perhaps even shifting the whole mast a little bit forward or aft, it would be
possible (as it is on most properly rigged boats). A little work at the chocks
and/or at the step. However you've always said that your boat sails well, please
don't think I am advocating this.

One thing to take a close look at, before such an undertaking, is what the
structural grid under the mast step is like. Usually (in a properly designed and
built boat) there is allowance for the mast butt to be moved a couple inches,
maybe less, each way; and there is sufficient structural strength to support it.

It seems that MC has never tuned a keelboat and isn't sure how masts are
adjusted; or it may be that his own much-bragged-about has it's mast fixed
rather oddly... perhaps the riggers did it on purpose so that he couldn't mess
it up?
