Beer (revolver) Lug Rig
by Lewis C
(Llanwrthwl, Rheadre, Wales)
I'm looking for any information I can get on some points that are basic to an ongoing ancient vessel design project, and hope that maybe someone reading this can help.
The Beer Lug Rig is close to a dipping lug, but it differs in that it is set up for another method of tacking.
When going about the sheet is hauled around the luff, followed by the sail, to the new leeward gunwale.
At the same time, the butt of the yard is hauled down to the vertical allowing the yard to revolve around the mast, following the sail, and is then allowed to swing back to its normal angle.
Can anyone say whether they've found this system used elsewhere other than the fishing village of Beer, in Dorset, UK?
And what would be the largest scale of sea-boat on which it would be practicable?
And what is the calculation (if it exists) for finding the load on a dipping lug's main sheet in, say, a stiff breeze ?
