Step 3.
Measure the distance from the beginning of the spreader bar adjuster screw
to the beginning of the spreader bar. This distance should be 59 mm on both
spreaders for now. This is a very powerful trim option on the boat and regu-
lates the spreader rake. The amount of required spreader rake varies from
team to team and influences the pre-bend of the mast. We will discuss and
measure this later in the manual.
Step 4.
Attach the spreaders to the mast with the clevis pins and rings. Make sure
the rings are on the bottom. Don't forget to tape the rings!
Step 5.
Take the rubber end cap and some of the supplied thin wire to secure the
diamonds. Wind the thin wire around the end of the spreader arm and then
put the two ends of the wire through the rubber end cap. Then slide the rub-
ber end cap over the end of the spreader arm.
