3. Tuning guide
3.1. Mast rake
The basic setting is the upper screw of the rudder spring on the transom. To
measure, do this:
Step 1.
Untie the shock cord of one of the trapeze wires and extend the trapeze wire
with a piece of rope of about 1 meter. Also make sure the side stays are on
normal tension (light weather setting)
Step 2.
Take the extended trapeze wire and pull it tightly to the bridle tang fitting.
Remember where the rope touches the bridle tang fitting, because this is
your reference point.
Step 3.
Take the extended trapeze wire to the transom and see where it touches. It
should touch the transition from transom to deck.
Step 4.
To put your mast forward or aft, first loose the side stays. Then adjust the
pin in the forestay adjuster (mast forward means pin down, mast aft means
pin up).
3.2. Spreader rake
We recommend the following settings measured between the mast-track and
diamond wies (you place a sail batten from wire to wire and measure the
distance):

With 160 kgs on board, we recommend that you use 45 mm of spreader
rake

With 170 kgs on board, we recommend that you use 40 mm of spreader
rake

With 180 kgs on board, we recommend that you use 35 mm of spreader
rake.
