THE VESSEL featured in these drawings is a shrimp trawler built by Atlantic Marine Inc. of Fort George Island, Florida, and is one of a series built by the yard for Japanese owners. These craft are somewhat unfamiliar to those of us used to European fishing vessels, and are specifically designed for shrimp trawling.
In certain types of fishing multi-net trawling has proved advantageous, several smaller trawl nets being towed instead of a single larger net. It is important that the nets a re kept down on the bottom to scrape shrimps from the sea bed, the catching power is determined by the area of sea bed scraped, the height of the head rope above the bottom being less important. The same total net spread can be achieved by two smaller trawls, which require appreciably less power to tow and lighter gear to handle.
The method used by shrimp trawlers operating in the Gulf of Mexico utilises other trawls that is by having other boards or doors streamed at the wings of the trawl net to keep the mouth open, as apart from a beam trawl which utilises a fixed beam to do the same purpose.
The towing speed is normally about two knots, the nets being towed from the ends of outrigger booms which project out from each side of the vessel, the starboard trawl being usually towed some 150 feet ahead of the port net.
A peculiar feature of the Gulf fisheries is the use of try net a small trawl net equipped with small otter boards which is used to sample the bottom for shrimp prior to streaming the main trawls. Being light, it is easily handled. The small davit on the starboard quarter is used to hoist in the net and doors. Normally this try net is left set and hauled inboard at intervals to examine the catch and ensure that the vessel 'stays on shrimp'.
The typical shrimp trawler has a layout similar to that shown in the drawings. The fish hold is situated under the aft deck, the winch or hoister is mounted at the forward end of the working deck. The mast is formed by two vertical posts which carry a cross beam, the ends of the beam having forks to allow the outrigger booms to be housed when in hoisted position. A strong well stayed boom is fitted to the aft side of the masts, with cross members at the extreme
