During the fast run from Chile to the Marquesas we carried our big jib wing
and wing with the mainsail for days at a time. The seas were big and the motioncaused
the jib sheet to squeal, where it ran through the sheet blocks and also rubbed
against one stanchion. Solution - Larry's ever-handy lump of beeswax. He rubbed
the wax against both the line and the stanchion. Instant silence. Only had to
repeat the procedure once every three days.
We also use beeswax, which is available at almost any chandlery, for lubricating
the sail track, the spinnaker pole up haul track and the mainsail outhaul track.
To keep sail repair twine from twisting or knotting while we work, we beeswax
the thread. In fact any time we are using thread or twine we rub it across the
lump of beeswax. It makes the thread work so much easier that I often use it when
I am mending clothes or re-stitching buttons.
Final use, according to a dentist friend, beeswax substitutes for temporary
cavity filler should you loose a filling at sea.
