JURY STEERING GEAR 335

while on a voyage from Galveston to Liverpool when the worm steering
gear frame broke down in heavy weather, totally disabling both steam
and hand gear. "Wire tackles were attached to the tiller. Manila
luff tackles were secured to the wire and led to the winch, turns being
taken in opposite directions around the drumheads. Lead blocks were
secured^abaft each, with the ends of the luff tackle falls rove through
them and bent together, making an endless purchase as shown in Figure
12. The tension tackle was used to take up the slack. The ship was
steered in this manner to her destination a distance of 2000 miles, and
this jury steering gear proved efficient.

JURY RUDDER.
When the rudder carries away at sea it will bang from side to side
with the motion of the sea, unless it is possible to secure it hard over
to one side or the other, and very probably the gudgeons and rudder
post may be damaged, but even after getting rid of it considerable
ingenuity will need to be exercised in devising and rigging up a jury
rudder from the material on board capable of steering the ship. Much
will depend upon the state of the weather, the size of the vessel, her
draught and the practicability of working under her counter at sea. It
would be a pretty hopeless task trying to rig up a working apparatus to
steer a ship with a cruiser stern, but with an elliptical stern and the
ship not too deeply laden an efficient jury rudder can be fitted at sea by
the exercise of patience and perseverance as proved by the successful
effort of Captain D. Forrest in the ss. Braddovey when her rudder was
lost in the North Atlantic. The figure and explanation are from the
Dolphin and Guild Gazette of January, 1929, by kind permission of The
Imperial Merchant Service Guild, and will give an idea of the job when
finished, but not of the strenuous and anxious time put in by those on
board during the dangerous and tedious operation.
EXPLANATION OF PLANS, Etc.
The wire used was 2\ inch flexible steel, and by using thimbles in the
eyes and movable fairleads and blocks no chafe or wear was encountered*
The derrick used was a 43ft. steel cargo derrick, the spider-band at the
head being used for the topping lift and steering wires. The goose-neck

bush and secured by using a washer and two collars each with two f inch
