M_Boats: Newbie question on sheaves and such

Sorry for such a basic question but my new Monty is parked and waiting for the 22 inches of snow to melt. So here goes.... what is a "sheave"? what does it look like? and where is it located? Is there an old monty manual that I might get my hands on to help with the rigging questions I might have? Thanks Doug __________________________________ Do you Yahoo!? Yahoo!
