worm gear and swing lifting keel

[samh]

Does anyone have any information (links, sketches, photos, description in words) of the lifting mechanism on keels ala the beneteau model?

Particularly interested in how the worm gear works, also parts suppliers etc.

I think u should look at the Farr 36, there are some pictures from 3d modelling available from http://www.farr36.org/boatinfo/dkdra...or/default.htm showing a bit of the system.
