III 12 - ADJUSTING THE POSITION OF THE MAINSHEET BAILS (25)
III 12 a - Adjust the position of the mainsheet bails (25) with the set screws which can be reached from
underneath. Fasten the mainsheet blocks on the mainsheet bails.
CAUTION : on boats with a mainsail track or mainsail block attachment on deck ahead of the main hatch
the mainsheet bails (25) must be re-positioned as far backward as possible.
III 12 b - Push the boom by hand over the lifelines as far as possible and tie a knot on the mainsheet so
that in no case the boom profile can be damaged by the rearmost shrouds when running downwind or jibing.
III 13 - INSTALLATION OF THE CONTROL LINES TO THE COCKPIT
REMINDER TO AVOID FRICTION
1. Only use good quality ball bearing blocks, which will have to be cleaned and lubricated from time to time
as per manufacturer’s specifications.
2.
Use ball bearing blocks with a sheave of large diameter.
3. Reduce as much as possible the number of lead blocks between the drum and the cockpit.
4. Reduce as much as possible the angle of deviation of the control lines.
III 13 a - Attach on starboard a ball bearing block (not supplied) to the mast foot at the convenient position
to lead the line into the middle of the drum at 90° angle .
III 13 b - Pass the furling line from underneath through the block, then through the hole of the drum’s shaft
and a tie small knot at its end so that the knot will be completely hidden inside the drum’s shaft. Please see
drawing 14.
III 13 c - To fill the drum with line turn the mandrel (16) by hand towards port side (seen from above) : the
furling line should exit from the drum on the starboard side.
III 13 d - Fit another ball bearing block at the mast foot to lead the mainsail halyard to the cockpit. Remind
to use the right type and dimensions of blocks.
III 13 e - Check that the exit from the mast of the mainsail halyard does not bring too much chafe.
