Re: Furling Boom on my 1972 P30
This is an old idea that never really proved practical.. there was another recent thread on the subject.
You'd be far better off to rig standard 'jiffy/slab' reefing, and leave the vang attached at all times. Rolling around the boom removes the ability to 'outhaul' the reef and usually results in poor shape. This is a far cry from today's 'in boom' furling setups, though they too have some of the same issues.
I think stowing the sail this way is more cumbersome and slower than conventional flaking too...
