Launching
Individual launching areas vary and common sense will determine the best order of
proceedings when launching the Viper. The boat launches from its trolley just like a
dinghy, and can be launched from a crane hoist, slipway, shore or beach with ease.
The boat will sail with just 0.5 metres (20”) of keel down, and although it is less stable
in this mode, it will not capsize.
Option 1.
The favourite option is to launch the boat from a crane or slipway, with a
convenient dock nearby. Put the boat in the water once the jib and spinnaker have
been rigged. Tie it head to wind to a dock or mooring, lower the keel and then hoist
the mainsail.
Option 2.
If option 1 is not possible, rig the jib and spinnaker, launch the boat, walk it
into deep enough water to lower the keel half down, sail the boat off under jib alone,
then drop the keel and hoist the mainsail in deeper water.
IMPORTANT
When you are ready to launch, ensure that the keel hoist purchase is securely
cleated. When craning in , double tie the loose end to avoid the keel suddenly
dropping in mid air.
Always ensure the keel lift purchase blocks are not “eased” and that there is
no slack or any “loops” caught in the purchase that may pull out and allow the
keel to drop unexpectedly.
Keep your fingers and feet and all ropes and controls away from the keel slot
and the top of the capping until the keel is fully lowered.
The boat will feel less than stable until the keel has been lowered at least half
way down.
24).
Once the keel is almost fully lowered, you will need to guide it onto the
mounts, using the hoist purchase to swing it into position. Then un-hook the
keel hoist line and stow it in the side locker.
25).
Fit the retaining bolts to the keel before leaving the dock.
NOTE: The keel must ALWAYS be secured in place with the keel hold down
bolts prior to sailing the boat fully.
When bringing the boat ashore, reverse the above process. Lower the keel back onto
the trolley cradle as soon as practical to reduce the loading on the rig.
TUNING AND SAILING TIPS
Keel
The keel should be left fully down while sailing. Only lift the keel for launch and
recovery, or in the event of grounding.
Cunningham or Downhaul
Increasing the tension progressively bends the mast, flattens the sail and opens the
leech. In lighter airs keep it fairly slack and progressively increase the tension up the
