Have you ever found yourself in a great position at
the first mark and turned to go downwind to find that your mainsheet looks
like a clump of spaghetti in the ratchet block? To date Laser sailors have
put up with this problem and tried to find ropes that give them tangle
free properties with some success. However with 10 meters of mainsheet to
let out to go onto a run, the sheet needs to be rather special. Steve
Cockerill from the
UK
tried in vain to develop something in
time for the UK Laser Olympic Trials in 1995, but he has persisted since
then and now manufactures a rope of his design which he thinks solves the
problem.
For Steve there seemed a
number of issues.
- Normal
8mm rope supplied with the standard laser package was good for the hands
but was never easy to run through the blocks. Of course everyone uses
6mm, which is even for Olympic sailors – a little radical.
- Normal
rope allowed the outer core to rotate around the inner core under load,
as the inner core was the load bearer, which reduced the stability of
the rope.
- Normal rope allows twists
along the line, which store up trouble just when you are not expecting
it.
The concept was to produce a
rope that was closer to 7mm than 6mm to help reduce the tangles and make
it a little easier on the hands. He wanted it to be lighter than a normal
6mm polyester rope and primarily he wanted it to be more stable than a
normally constructed mainsheet. Steve figured that it was the properties
of the inner core that made the rope more likely to tangle. His idea to
solve the problem was considered by the rope manufacturer to be more
revolutionary than evolutionary. Steve had the idea to put a low tech high
stretch rope as the inner core of the rope. This would make the core
lighter and leave the outer core to be the load bearer. The outer core
would therefore also grip the inner core under load - which would help
maintain stability. Steve calls it ‘Polilite’.

Since
then - Rooster Has Developed a 6mm extra light mainsheet that won Gold and
Silver at the Olympics in the Laser Class - and a 9mm that is used on OK's
up to J24's as a non tangle Mainsheet.

Suffice to say this line has
won Gold, Silver and Bronze in Sydney in the Laser class - it has also
been used in other classes with great success - in 2000 it won: the
Topper Nationals, Enterprise Worlds (jib and mainsheet) Solo Worlds and
Nationals. It has also been used as an asymmetric spinni sheet in an ISO
and Laser 4000.
IMPORTANT: It
is strongly advisable to wash the Polilite mainsheet in the washing
machine on a cold wash with a little powder to wash out any oils from the
rope. These oils were used to allow the rope to be made extra tight with
more body, so that it kinks less when it is used, but would make the rope
slippery for the first 3 or 4 days of use. Always treat it with respect
and coil it up (climbing rope style) so kinks or twists never form. Please
check the outer core for wear as this is the load bearer – we recommend
that you change the rope after 1 year of weekend use. When you rig the
boat – please ensure that all the coils and kinks are taken out of the
rope before you dead end it in the boat (the rope will not absorb or
create kinks from then on). I throw mine across the boat park and pull out
the twists before I rig it on the boat
