Butterfly Adjustments
TWO PIECE MAST
The two~Wpiece mast joint requires no mechanical fasteners. If the joint becomes stuck, grasp
the mast close either side of the joint and shake it as you pull it apart.
MAST RAKE
A good rule of thumb for determining mast rake is to keep the mast perpendicular when the boat is
at rest in the water. You would then have no forward or aft rake. When the mast is raked straight
or back, the boat will tend to turn into the wind when close hauled on a windward beat. This is a
desirable situation, as a boat with no one aboard will turn into the wind and come to a stop. It
is known as a weather helm since the boat always steers itself into the wind (to weather) and must
be held on course with the tiller. As the mast is raked forward the weather helm will diminish and
will become a lee helm at which point the boat tries to turn away from the wind and run off on a
reach. For safety~Rs sake, a lee helm is undesirable and should be avoided.
DRAIN PLUG
The drain plug is located in the transom next to the lower gudgeon. Occasionally, when the boat is
out of the water, remove the plug and lift the bow to check for condensation that may form in the
hull. The plug can be tightened by snapping the lever in and also by screwing the lever clockwise.
If the plug is over tightened, it will be difficult to remove as the end of the lever screw will
pull through the rubber, expanding it. If this happens, screw the lever until it is very loose,
and wiggle the plug out.
DAGGERBOARD SNUBBER
The snubber may be adjusted to change the tension against the board. The opening between the rubber
should be 9/16". When the daggerboard is dry, it may seem too tight. When the board is wet, it will
work much easier. If the snubber still grips too tight, round the sharp edges with a few passes of
sandpaper. The snubber may be adjusted by loosening the screws and sliding the rubber in or out.
RUDDER
The rudder blade should pivot freely with the coil spring doing all of the work in holding the blade
up or down. To adjust pivot tension, loosen the lock nut, turn the screw, and then retighten the lock
nut. The screw is threaded into the casting so the adjustment cannot be made by turning the nut or screw only.
TILLER
The hiking stick and tiller pivot bolts should be kept snug but not overly tight. The tiller is held up
off the deck by a nylon button resting on a pin on the rudder. If the tiller pivot should wear enough to
allow the tiller to touch the deck, a shim can be placed under the nylon button. Simply pull the button
off, insert a washer or any hard material and tap button back into place.
MAST STEP
A light coat of Vasoline or non-staining grease spread on the mast step will facilitate the pivoting
action and reduce wear. If you are launching off of sandy beaches, it may be well to omit the grease
or use a dry lubricant or wax.
