 called the trawl-warp, and is the only connexion between the 

 boat and the net when the net is overboard. The ropes 

 passing obliquely from the block to the two sides are called 

 the bridle, and serve effectually to keep the open mouth of 

 the net square to the front, when the net is drawn along over
