How does the Scott
Boomlock work?
|
| A preventer line is attached to strong
points aft of the mast on either side of the boat and is wrapped around
the Boomlock drum, as in a winch, in
a way that eliminates jamming or riding turns. Boom swing is controlled
by a light line which runs forward from the Boomlock
to the mast and then back to the cockpit. |
 |
| This light control line operates a toggle
linkage inside the Boomlock which by
means of two friction control eyes, regulates the friction between
the drum and the preventer line. The preventer line is not rigged
taut, so the boom can still swing freely until the control line is
operated. |

How do I use the Scott
Boomlock?
|
|
Using Boomlock Two, when
you are sailing downwind and the boom is out, you pull the control
line to engage the lock and hold it in a cam-cleat. If the mainsail
is backed by a windshift, the boom will then be prevented from swinging
across. You can then either alter course to fill the mainsail again,
or if you decide to gybe, you can release the control line slowly,
and the boom will come across under control.
The operation of Boomlock One
(for smaller yachts only) is the reverse of this, in that
you pull the control line to release the lock. On this model
the lock is either on or off and you cannot use it
to regulate boom swing.
