The ideal fishing boat is one vrfiich car. bring to market the greatest 

 possible quantity of fish in the best condition of freshnesSo If we look 

 at the actual capacity of boats of various sizes.

The above figures represent the standard quantities which can be 

 stowed v/hen the catch is properly refrigerated with ie-e to keep it; fresh. 

 The amount of ice used varies mth the season and the length of the trip, 

 but in general it is 25/6 to 35j6 of the weight of the fish to be refri- 

 gerated. When fish are kept iced for use as fresh fish, each 100 kan 

 C^21 lbs„_7 of fresh fish requires about 40 cubic feet of spaceo The 

 amount of ice carried by fishing boats is as follows § 



Size of Vessel Average Weight of Ice 



70 - 100 tons 32 tons 



100 =• 150 tons 53o7 tens 



over 150 tons 54- tons 



These figures will vary depending on the efficiency of the insulation 

 in the fish holds. Larger vessels are installing refrigerating machinery » 

 Temperatures in the fish holds should be from 25 to 35 Fo 



5, Personnel carrying capacity 



Since skipjack fishing is based on individual skill, it is necessary 

 to carry as mar.-./ fishermen of the highest degree of skill as possibleo 

 This will nat irally be governed by the living space and acoommodaticn s 

 in the boat and by the available working facilities^ By working facili- 

 ties are nieant the bowsprit and fishing platforms, for the construction 

 of which there are various designSo 



Tne bowsprit is of steel girder type, combined '.vith galvanized gas- 

 pipe. It is broader at its outboard end and the inboard end is attached to thp 

 fishing platforms. It is designed to permit more men to engage in the fishing 

 t^.an was possible in the past, and is so constructed that the fish taken will 

 ciide along it into the boat. 



The fishing platforms are installed along both sides of the boat from 

 bow to stern, and forward of the gangway in the middle of the boat the 

 bulwarks are extended to their outer edges, and the footboards on their 

 upper surfaces are covered with water-tight planking 5 aft of the gangway 

 the footboards are mado of galvanized gas=pipe„ IhB whole construction 

 is strong enough to .vxTihstaad the pounding of the waves.
