12) Secure the starboard mast

to the starboard ama. 

Use the same procedure as the port mast.

13) Attach the starboard mast

to the compression strut. 

Move the top of the starboard mast closer to

the port side so that the compression strut will

reach. The starboard mast will be at its limit of

articulation at this point.

Get the threads started onto the starboard

mast. As you spin the compression strut onto

the starboard mast it will partially unthread

itself from the port mast. The starboard side

should bottom out while there are plenty of

threads still engaged on the port mast.

When de-rigging, simply unscrew it from the

starboard mast and then unscrew it from the

port mast.

Always put the compression strut onto the

port mast first. The compression strut screws

onto each mast. 

(The threads on the port mast

are a little longer.) 

Lift the compression strut from the trailer. Lift

one end to insert the threaded pin on the port

mast into the hole on the end. Screw the com-

pression strut all the way onto the port mast.

Let the compression strut hang from the port

mast and prepare the starboard mast.

NOTE: The compression strut can be installed before or

after the port mast goes up.

14a) Raise the starboard mast

and compression strut. 

Walk the mast up. Holding tension on the

backstay, walk back

to the cockpit and

hook the backstay to

the pad eye on the

hull. Make sure that

the lashings are com-

pletely extended.

Use a small amount

of force to get the

hook onto the pad

eye. The mast should

be secure at this

point. Now is a good

time to double check

the rig before you completely tighten it. Make

sure that the compression strut is engaged

onto the pins at each end. Make sure that all

the wires are straight and not kinked. Make

sure that the outer beams are completely

engaged into the center main beam.

14b) Backstay Tension

We are using a 3:1 purchase system on the

starboard backstay. This will allow you to com-

fortably hook up the backstay and tighten the

whole rig.

After checking the rig, tighten the system all

the way until the cleat bottoms out on the

stainless steel hook. Cleat the line and tie a

bunch of hitches in the rope to use up the

excess line.
