[Alberg30] profurl roller furling (with a note on the isolatedground)

[Larry Morris]

Removing the core severely weakens the line.  The core is designed to carry
the majority of the load on the line.  The better solution to the problem
decribed below is to remove the cover from the line.  You reduce the
diameter of the line without significantly weakening it.

  One other trick I used on the Profurl I put on the A30 Isa Lei, was to
remove the core from the first 25 feet of the furling line.  I discovered
that the drum was getting too full and jamming.  This dosen't affect the
strength to the point of worry about breaking and allows the furling line to
be large enough to hang onto when rolling the sail up in a blow.

  As to the ground on the Perkins (same on my Volvo) it is as Rob suggests
to isolate the DC from the prop and other things in the water.  The ground
to the block and from the block to the ships ground is just in case you have
a short.
