of the haul-out line and net, while paired upstanding line

as one intended for catching shrimp, but in no sense to

shrimp bodies are delivered selectively to appropriate
hold spaces wherein they are refrigerated and held until

The drums 61a, 61b carry the trawl warps T1, T2 where
by the net is dragged during trawling such warps running
through guide blocks 96a, 96h and over opposite sides
of the vessel, near stanchions S1, S2 where water reaction

is hauled in and reset, and how the catch is segregated

through the main hatch upon raising the hatch cover 80,
or through the auxiliary hatch upon raising the smaller
hatch cover 81. Also, these chutes must not hinder rais

The main hatch cover 80 is hinged along its forward
edge, at 83, to the hatch coaming 8. It can be in its
closed and secured position, as shown in FIGURE 6 in
full lines, or in its open position, as shown in dot-dash

lines. The smaller auxiliary hatch cover 81 is hingedly
