268 YACHT EQUIPMENT 



mometers, water-bottles, soundings, tow nets, dredges, 

 and trawls, as well as for hoisting boats and anchor, 

 cargo and coaling work. With winches (as with 

 much other gear), the owner, master, and engineer 

 must settle the exact specification, according to the 

 work to be done. We can only give the most general 

 indications as a guide. 



One may use (i) either a regular trawling winch, 

 on the barrels of which the rope is stored ; (2) or a 

 cargo winch, which will haul the rope but not store 

 it. Of these two types, there is no doubt that the 

 regular trawling winch is much to be preferred. It 

 will not only serve for the ordinary work of a cargo 

 winch, but when scientific work is required it will save 

 deck space and hands. 



We figure a commercial trawling winch, showing 

 the usual two hauling and storing barrels in the centre 

 of the engine. For really deep-water work this type 

 requires some modification. In the first place, if 

 required for trawling and dredging only, a single large 

 barrel is better than two smaller barrels, the divisions 

 between the latter having been known to burst and 

 cut the rope under pressure. In the second place the 

 brake wheels should be cast solid with the barrel ends, 

 and strengthened by radiating ribs, in order to resist 

 the enormous lateral thrust of a great length of rope 

 wound under tension. But if it is proposed to use 

 closing tow nets and other apparatus with small 

 messengers, which require a slighter rope (p. 279), in 

 addition to trawl and dredge, it might be well to 

 retain the double barrel, using one barrel for each 

 rope, and strengthening the division between them. 

 In this case the barrels should be clutched separately, 

 which is not always the case with commercial trawling 

 winches.
