4. Standing in the cockpit or on cabin top, (pop-top down and hatch closed) walk the mast up and
have someone secure the headstay. Don’t let go of the mast if you go forward to attach the headstay.
5. Tighten lock nuts on turnbuckles. Depending on the type of turnbuckles on your Clipper, they
should have either cotter pins in place, lock nuts tightened, or even be safety wired. If not, the turnbuckles can easily come loose, causing you to lose a mast overboard.
TUNING YOUR RIGGING: It is recommended that a qualified person be on hand while the rig on
your new Clipper is tuned for the first time. Later you may follow these steps in tuning your rig and
you will be surprised at the improvement in performance that will be made. Caution: Do not overtighten the standing rigging on your Clipper. It should no sound like a guitar string!
First with your boat sitting at the dock:
1. The headstay and backstay should be tightened equally. Of all the rigging on your Clipper, the
headstay and backstay should be the tightest. This is so that the headstay will not sag excessively
while you are sailing to weather under jib or genoa. The sailmaker has allowed for about 10” of sag
in your jib so any more than this under load is reducing your performance. A simple test of headstay
tension is to stand on the foredeck and tug on the headstay. With a good strong, short tug, you
should be able to flex the headstay five or six inches.
2. Next, tighten up the shrouds. Both sides should be tightened equally. Both turnbuckles should
have an equal number of turns, and should be good and snug, but not as tight as the headstay.
3. Now tighten all of the lower shrouds equally. These will not be as tight as the uppers, but just to
the point where the mast is in column or straight. To determine this, sight up the sail groove in the
aft edge of the mast. It should be in a perfectly straight line, both laterally and fore and aft.
4. If the mast is not in column, re-adjust the upper and lower shrouds until you have the mast in a
straight position.
5. Now you are ready to perform the fine tuning under sail. In a breeze of 8 to 12 knots, take the
boat out and alternately sail on one tack and then the other. Sight up the mast and see if it is still in
column. If not, tack and adjust the turnbuckles when they are not under load. If you have adequate
headstay tension to prevent excessive sag while under sail, you should never have to touch the
headstay or backstay to get the mast in column. All adjustments will be made to the upper and
lower shrouds. You may have to repeat this operation for five or six tacks until the mast looks perfectly straight. Now pin or tighten the safety nuts on your turnbuckles.
After you have sailed several hours in some stronger winds, you will notice that the shrouds have
stretched. This is perfectly normal the first few times, and it will he necessary to re-tune your rig if
you wish to obtain optimum performance from your Clipper.
ADJUST
ABLE BACKSTAY: On some Clippers an adjustable backstay is supplied. It is primarily
used for racing. This can be tightened prior to a race to minimize headstay sag, but should be
slacked off after you return to the dock. If you find your self in exceptionally strong winds, it is a
good idea to increase the tension on the backstay a little with the adjuster. This will keep the mast in
compression and may prevent a rigging failure. The primary reason for rigging failure in heavy wind
conditions is too much sail and too little backstay tension.
