Hinged mast and sprit

Hi Folks,

Just percolating some ideas about these two topics and thought I would
share them with you, and perhaps get some good comments :)

Its a bit large, so Ill link to it as a web document:

http://www.ennui.net/~timothy/Boats/Hinged_Mast.html

I am -certain- none of these ideas are new, but I hoped to present
them in a cogent form all in one place.

If people forward me designs for this sort of thing, Ill add them to
the page, by the way.

Thanks in advance for your critique of the ideas!
