Vang
Have the rope strops and vang blocks attached as shown above to the mast collar. The other end should be attached
as the below illustration shows. There are 3 vang ropes in the rope bag, a 2.5m which is used from through the cleat
and hull at each end and has a single Harken sheave on it. The 2
nd
vang rope which is 2m long and this goes from the
single block though the single block with a becket up to another single block and then back down to the becket. The
3
rd
vang rope is tied off onto the shackle attached to the vang and mast strap in a bowline, then goes up through the
single Harken air block (which is shackled to a clip that attaches onto the vang slide on the boom) then back down to
the single Harken block. Also see the mast base picture to get a good understanding of the mast end of the vang
system.
Spinnaker Sheets and Spinnaker Knots
The spinnaker sheet rope is a special type of 6mm rope. This enables you to use it in a 6mm form or taper it down if
you like after the spinnaker sheet cleats position into a smaller lighter diameter of rope. We advise clients to put in
spinnaker sheet knots before the spinnaker sheet blocks on the side deck. These should be positioned so the
spinnaker can be bagged in either of your preferred bags with adequate room on the sheet, but not so much that the
spinnaker can blow out and twist or capsize the boat at an undesirable time. A stopper knot is okay for this. You can
also loop it through itself if it is easier and if you prefer to change these on the water with more ease. You will find
these fittings in the fitting bag.
Mainsheet
Assemble the mainsheet as the picture below shows. The boom fittings will be found in the fitting bag.
