That must explain why the trailer bunks for the two different models
are exactly the same.

Y'know, this is like arguing with a religious loony, only
this guy is waving a Macgregor advertising brochure like
it's Gospel.

I have "checked them out" and that's why I say they're the
same.... because they are.


(Incidentally, we
went through this same discussion on the asa ng ad nausium for several
months last year. Someone finally checked out the hulls of the two
boats and admitted that they were, in fact, substantially different.)


Really? Who?


"Upper bearing"?? What does the mast bear on at the upper end?


As understood, it bears on the movable elements of the upper bearing
structure, which are rotatably constrained within the fixed elements,
which in turn are fastened to and constrained by the lateral stays and
the jib stay.


Interesting... most rotating masts just lead the shrouds &
forestay to a common point, no bearing needed...



BTW what benefit does a rotating mast give the boat?



They were developed on competetive cats and trimarans, because they
improve the forward force vectors by eliminating turbulence behind the
the luff of the sail caused by the mast, which projects into the airflow
beyond the luff and tends to break up the airflow in the region behind
the mast. In any event, owners of competetive multi-hull craft have
been using them for several years. - Whether, or by how much, the system
improves the Mac's response I really don't know.


So you repeat all this blah-blah because it impresses you?

Rotating masts are great on boats that are light & fast
enough to sail at high speeds. C-scows use them, Tasars use
them, and many multihulls. They work better with a means of
controlling the rotation, which the Mac26M doesn't have

On slow boats like the Mac26M, it doesn't do anything except
impress people who don't know better.




Lots of owners seem to like their 26Xs and the new 26Ms. - They don't
want to part with them.

I'm sure that's true. And the Mac discussion lists are like
a church meeting, everybody loves & praises their boat and
calls sailors with other boats stupid for not realizing it.

.... - In any event, hope you get some good sailing
weather this weekend.


Thanks, but unfortunately we're not going sailing this
weekend, we're driving hundreds of miles to overeat & watch
TV. Not my choice, but it's tradition.
