[MHml] Bi plane rigs.

[Robert]

That is not the way I read his comments.  More like "W" than a tacking Harry
proa.  Build only one mast, one mast base,  one sail, put storage equal to
the mast weight including the structure in the opposite hull and now you
have a free standing rig with all of its advantages such as being able to
insert the mast with the hull on its side, self depowering in the puffs, and
no blanketing.  Would it really be a deal breaker to have the mast 20%
heavier?  Or are you really set on trying the biplane rig?  I hope you go
for the biplane because I am with Bill in that I want to see more work done
on it.  I think it could really be a great shorthanded rig for cats.

         It seems to me Rob that you are cunningly gravitating the 
discussion towards the idea of the original rig in an original hull 
with accommodation in the other hull, which since it is the wrong 
shape to provide much in the way of comfort should be replaced with 
something that does, and, voila -  a tacking Harry type outrigger. 
There may well be all the reasons which you mention in favour of such 
a device, but right now it just does not grab me. The boat has to be 
simple to modify from what is, time is of the essence and I do not 
put in 14 hour days any more, at least not 14 hours of steady work, 
14 hours including naps maybe. I do agree that it is less time to 
build one longer mast than 2 shorter ones, following that path I 
should just leave everything as a standard C Class with a boom tent 
and a primus, and take along a crew member to help put the mast up, 
yet an original requirement was to be able to do everything myself 
and that stays pretty central. So I will keep plodding along in that 
direction and will leave rig decisions until later.
