Stick for Rudder-Post of Catamaran
Evidently it would be a most difficult undertaking to steer the catamaran
with independent rudders, and we must devise a method by which one tiller will
control both.
Figs. 196-198
Rudder-Post of Catamaran
Fig. 201 shows how it may be done with a system of Pulleys or
blocks and till-lines, or you may make a short oaken stick of the form shown in
Fig. 194, A. Bore a hole through the center, as is shown in Fig. 195, B. Trim
off the top to fit the tiller-handle (Fig. 196, C). Saw into all the four
corners of the square stick to form a shoulder to rest on the bench. Fig. 197
shows the shoulder at S. Plane off the square corners of the wood below the saw
cut.

Rudder Bench of Catamaran
After this it is quite a simple matter to round it off below the shoulder
(Fig. 197, E).

Half Hull of Catamaran
After slipping the rudder-post through the two holes bored for the purpose in
the rudder bench, drive through the post a good, strong oaken or hickory peg
(Fig. 198, F), and bind the cross-pieces tightly with tarred twine. The end of
the cross-sticks should be firmly lashed with tarred or painted twine. A large
screw-eye may be now put in each end of the cross-stick or near the ends,
allowing the screw ends of the eye to protrude far enough to screw on a nut.

Tackle for Steering a Catamaran
Now we must have two long, strong hoop poles to connect with the rudders by
means of bolts and rings, as shown in Fig. 191. All that is now necessary is to
fit your tiller-handle over the top of the rudder-post, and the steering
apparatus is finished. Fig. 201 shows another plan for steering with a helm like
Figs. 202 and 203.

The Side View of Helm
The mast is stepped in a bench at the bow similar to the rudder bench. Each
consists of board benches bolted to heavy plank supports and bolted to the deck.
The material used should be as light as possible, consistent with strength. The
dry deck can be made of neatly planed boards, and the whole craft may be as neat
and well done as the skill of the maker will admit. Hulls with a swell on each
side jam the water between them and retard the boat; so if you build the
catamaran with half hulls you will do away with this objection. Fig. 200 shows
diagram of hull; Fig. 202, plan of craft; Fig. 203, the helm.

A Tom Thumb Catamaran
could be built just large enough to hold one boy. The dry deck may be made
with bamboo poles, in the form of a seat for the sailor, and if a foot-rest is
added below, he may sit perched in his dry seat like a horse-jockey in a sulky,
where he can manage his little craft in weather that no other small boat, could
stand. Some people say that under a heavy sail and a hard blow this style of
boat will rear up at the stern and go end over end. If this is true, it is
because the craft is too short and dumpy, or has too large a spread of canvas.
Even full- rigged ships have been known to run their bows under.
There was a good-sized catamaran wrecked in Flushing Bay the same day that
the writer upset in his canoe, but from the looks of the wreck, with its sails
torn to ribbons, it seemed probable that the sails had been carried away, and
the craft had then drifted ashore. The wreck showed no signs of having turned
somersaults.
Two old single shells would make a beautiful Tom Thumb catamaran, and they
would be far more likely to sail Up in the air than to stand on end, but all
these gymnastics on the part of the boat can be avoided by not venturing out
during a gale or by shortening sail when the wind is strong. Never be misled
into thinking it seamanlike to carry full sail when other boats are reefed. Too
much sail retards the boat as much as too little. In all yacht races the
skippers never hesitate to take in sail when it is necessary any more than they
do to shake out a reef when more sail is thought to be beneficial.
Danger of False Pride
Learn to manage a small sail first and then a larger one. Do not be ashamed
of blunders. Why should you? Is a baby ashamed to creep before it learns to
walk? On the contrary, the baby is very proud of its newly acquired powers of
locomotion. Nobody is a born sailor. The best seaman was once a land-lubber.
