The ends of the warps are attached to the trawl doors. A series of half-round guards made from split 3-inch steel pipe is welded between the rub rail and roof line to protect the sides of the deck house from the trawl doors (figs. 1 and 6). The net reel, which is used for retrieving and storing the trawl sweep lines and net, has a drum with 41-inch diameter flanges and a 10-inchdiameter by 50-inch long

Fig, 7 - Hydraulic winches used in trawling. 8-inch diameter sheaves, mounted on the top deckdirectly above the winches (figs. 1. 2, 3, and 6). The sheaves move freely on a l^-inch diameter by 13-inch long horizontal steel shaft to provide unassisted level winding of the trawl warps during hauling. A 2-inch, extra-heavy, steel pipe is mounted vertically from the main deck to each base of the sheave housingfor support (fig. 6). The warps then lead aft where they pass through two 4-inch wide by 8-inch diameter trawl blocks hanging from 4-inch diameter, extra-heavy, steel pipe stanchions located at the stern. The 6-.
