barrels inside to turn in such a way that the ice is broken or picked up 
fine enough for use. 
(c). Boats . 
Fig. 19. — A trawler’s boat. 
The boat (see Fig. 19) used on the trawlers for transporting the fish 
from the catcher to the carrier is an open, clinker built, keel craft, wide, 
and rather clumsy looking, with full rounding bow and heavy square 
stern. It is strongly built, and has a large carrying capacity. The 
boats carried on the larger trawlers are about 17 feet long, to 7 feet 
wide, and 2 feet 9 inches deep. 
The dangerous work performed by these boats is detailed elsewhere, 
but it may be said here that, because they are frequently capsized and 
the men in them drowned, an effort has been made to provide them 
with some kind of suitable appliance which may render them unsink- 
able and insure the greater safety of their crews. Many devices for 
attaining this much-desired end were shown at the London Fisheries 
Exhibition, in 1883, but none of them met with the full approval of the 
examining jury. 
(d). Doddle Net or Diddle Net. 
A dip-net, called a u doddle w or “ diddle v net, forms part of the equip- 
ment of a trawler, and is used to dip fish out of the trawl when an un- 
usually large catch has been made and the weight of fish in the net 
is too heavy to hoist in. At such times a hole is cut in the back of the 
trawl and enough fish removed with the dip-net to lighten it ; on some 
extraordinary occasion perhaps two or more holes have to be made in 
the net. The doddle net resembles the dip-net used by the New Eng- 
land mackerel seiners, though it is not quite so large as the latter.
