Use of the clutch
The wildcat is connected with the main shaft by means of the clutch.
The clutch releases (disengages) through the lever that, once inserted in
the barrel, will have to turn counterclockwise. When rotating clockwise,
the clutch will be applied (engaged).
Anchoring
The wind and the sea conditions have an impact on an anchored yacht.
Make sure the anchor is firm in any situation. It is necessary to
understand the principles of the chain length and its effect on the
performance of the anchor.
The radius is technically defined as the ratio between the length of the
chain and the vertical distance from the foredeck to the bottom of the sea.
The chain length depends on the type of anchor, on the sea bottom, on
the tides, on the wind and on the sea conditions.
The minimum chain length is 5 times the depth with calm sea; under
normal conditions 7:1 and under critical conditions up to 10:1.
Radius = Chain length
Foredeck height + water depth
As it is necessary to know the length of the chain to be used for mooring.
Chain length =
(foredeck height + water depth) x radius
Anchor retrieval
Start the yacht engines. Make sure the clutch is engaged and pull the
lever. Press the relative control button and start retrieving the anchor. If
the anchor windlass stops without any reason, the anchor might be stuck
and therefore the anchor windlass protections will activate, due to the
effect of the effort.
In this case, if after several attempts the anchor windlass remains stuck,
we suggest to maneuver the yacht, to refloat the anchor.
Check the raise of the last meters/feet in order to avoid bow damage.
Anchor deploying
Deploy the anchor by means of electric controls or manually. To carry out
this operation manually, open the clutch and leave the wildcat free to
rotate on its shaft.
Let the chain fall into the water. Turn the lever clockwise to slow down the
anchor fall.
For the electric anchor deploying, press the relative control button. In this
case the deploying is perfectly controllable and the unrolling of the chain
or of the line is regular.
Once anchored, lock the chain with the proper cable.
The anchor and the chain may cause damages to the yacht hull if the
anchor windlass is not operated carefully.
We suggest to carry out the operation by means of the remote control
located near the anchor windlass; this will allow to check the lifting and
lowering speed of the chain and the entry and exit of the anchor shaft into
the anchor roller. Namely during these operations, an excessive gliding
of the chain or a wrong entry or exit of the anchor shaft from the anchor
roller may cause damages to the yacht foredeck.
Pay utmost attention: do not approach too much to the moving
parts to avoid dangers and injuries to the people.
S
CAUTION
Lock the chain with proper wildcat locking before setting up navigation.
