SHADOW ASSEMBLY INSTRUCTIONS
3. Attach the turnbuckle at the bottom of the diamond wires to the shackle
on the front of the mast, taping the split ring for security.
4. Tension the diamond wires with the turnbuckle, until the mast prebend is
approximately 38mm (1.5”) – this can be measured by pulling a thin cord
tight between the tip and bottom of the mast and measuring the distance
from the cord to the mast track.
5. Once the correct prebend is achieved, look down the mast track from the
tip. If the mast bends to one side, unfasten the diamond wires and reverse
the diamond wires then repeat step 4; if this doesn’t cure the bend some
packing will be needed on one diamond wire. Slacken the diamond wires
and fit a piece of packing (e.g. a discarded rivet stem or similar diameter
piece of stainless steel) between the spreader and diamond wire. Re-tension
the diamond wires until the prebend is approximately 38mm (1.5”), then
look down the mast track and check for any bend. Repeat with different
diameter packing until the mast is straight.

eal around the diamond fittings, then secure the small
rotective plastic covers over the diamond fittings with
ilicone sealant. Take care that the diamond fittings are
bsolutely sealed in the mast, since any gaps will allow water
into the mast and make capsize recovery difficult.
