and clamping the foils.

Norseman/Sta-Lok installations are identical to swaged
wire at this point.
November 2005
Use 6 mm allen wrench to secure to the drum assembly
using the three screws provided. Use blue Loctite on
screws.
Tip: Insert all three screws BEFORE tightening.
Raise the foil so the top rides over the swage fitting at
the top of the headstay wire and is within 2" (51 mm)
of the pin holding the stay to the masthead toggle.
Tip: Walk away from the boat and check the height
by looking at the top of the foils with binoculars.
Failure to raise the foils will result in considerable
friction while furling. Raising foils too high may
prevent the foils from rotating.
Insert the torque tube screws and use the 6 mm allen
wrench to securely clamp the foils in a raised position.
Rod Instructions
Rod installations are identical to swaged wire at this point.
