The jockey pole is used, especially on bigger
boats, to get a better pull angle for the guy
and to keep the guy away from the shrouds.
The preventer stops the main boom from
whipping across the cockpit in an uncontrolled
gybe. This is one of the most dangerous
incidents that can happen when sailing.
Normally the preventer is attached to the
boom at nearly the same point as the main
sheet. It is then led forward to the stem to
obtain a better pull angle to the boom and a
more elastic system, through a block or
around a cleat and back to the cockpit where
it is cleated.
NB! A quick release method is essential for all
preventer types. Also use a preventer when
on or near a dead run when using the genoa
as headsail. Alternatively the sheet may be
moved to the rail as shown on the figure. But
a dedicated preventer is advisable, even if it
doesn't lead all the way to the stem and back.
Always ensure that it can be released quickly,
preferably from the cockpit. |
