Main Sheet Modification:
Yachts of this nature, would be fitted with a Traveller, which would be used to help shape the Main Sail. Also, the route of the main sheet, has a lot of twists and turns to get out of the cabin
and up to the Boom. Plus, it has to pass through the tube and bend at its edge.
The starting point of the control would be from the cockpit
, especially if it is a Single Handed yacht
. The ideal place for the traveller, would be on the roof of the cabin
. To keep physical disruption to a minimum, I decided to use the original boom running gear pulleys
The termination of the MainSheet would now be at the traveller on the cabin
1. The cleat was removed from the cockpit
, and the eye bolt was replaced by an S hook, screwed to the cockpit
deck( see picture 1).
2. A hole was drill
ed in the cockpit
, adjacent to the cabin
hatch, and in a direct line with the main Sheet control system
. This will allow the main Sheet to pass directly from the cleat. Through the pulley assembly (withought going round the pulley), and straight aft to the cockpit
3. A brass tube
was glued into the hole, flush with the cockpit
surface and extending inside, towards the mainsheet control system
(see pictures 1 and 2).
4. The Traveller was formed from a length of brass rod, (approx 300mm long), formed to the same curve as the cabin roof
. Slide the pulley onto the rod so that it runs freely. Make a 90 degree bend at each end, the length of the traveller apart. These 2 legs will pass down into the cabin roof
, leaving about 10 mm for the pulley to run from end to end. Plus about 10mm at each end of the rod, which will be bent up against the inside of the roof and glued.
(see picture 3 & 4).
5. Mark the cabin roof
where the traveller is to be mounted. I chose to mount the traveller directly under the boom pulley.
I have made a revised sketch which is taken from the original plans
for guidance. See picture 5.
Note: make sure the pulley is mounted on the rod between the two bends.
6. Drill the holes in the cabin
, pass the ends of the rod through the holes. I put a 10mm piece of wood under the traveller rod, next to the hole. This allows you to hold it securely, while you bend the rod out, on the inside of the cabin
. Apply plent of glue or resin
to secure it. Do the same at the other end of the rod, and leave to set.
With the cockpit
removed, and the mainsheet control system
in place, take the free end of the main sheet and pass it through the new hole in the cockpit
. The cockpit
can be secured by the 4 locking pulleys
Now pass the mainsheet through the S hook and up to the boom. Adjust the S hook to suitable angle.
When the yacht
is rigged, the mainsheet is passed up to the end of the boom pulley, along the boom, over the pulley and down to the traveller pulley.
With the tx/ex active, pull the mainsheet right in, and the trim set right out (this allows for final tightening).Secure the mainsheet to the eye of the pulley, ( I use a figure of 8 knot ). Now adjust the trim on the joystick to pull the main Sail tight.
Finally, run the servo
right out, and back in a few times, to make sure it works properly.
Move the boat round so the wind cones from a different angle, and watch the traveller as the sail is pulled in and out.
Now you are ready to sail.
May your wake be long and straight.
