SAILING CRAFT AND MOTOR-PUNTS — 299 
(gun-metal) shipped on one tail shaft. The propellers should 
have blades of a fine pitch, i.e. the set of them must not be of 
much twist, for, being in a tunnel, they will simply churn if 
otherwise, and speed in the craft will be lost. We cannot 
specialise on the motor; suffice it to say that a good 
petrol engine of about 12 horse-power (two cylinders) of 
modern and up-to-date pattern, installed in the launch as per 
sketch, will, if in good order, develop enough power to 
propel the craft along at a speed somewhere between eight 
and ten knots per hour. If a large punt-gun is mounted on 
the fore-deck, the petrol tank will have to be fixed under the 
after-deck, though under the fore-deck is its correct place. 
For the wildfowler’s motor launch a good silencer for the 
exhaust gases from the engine is an absolute necessity, if 
success is to attend the craft as a shooting boat. 
The launch hull may be made of wood or steel—wood for 
preference. We would give some remarks on the building of 
the launch, and detail sheer and half-breadth plans for its con- 
struction, but fear that in doing so we may be trespassing 
upon another subject, and one not intended to be covered 
by the title of this book. Unlike gunning-punts, launches are 
everywhere upon the market. A practical launch-builder will 
be able to strike his own lines and produce the wildfowler’s 
launch from the design herewith. I think all that may be 
found differing from ordinary launches in the design here 
figured, besides the tunnel arrangement, will be the low-set 
bow and freeboard, extra long fore-deck, narrow side-decks, 
and coaming to inboard quarters. This launch will be found 
a suitable one to make fairly long trips in from harbour; yet 
it is not of sufficient size to be of service as a coasting cruiser.
