SUGGESTIONS FOE IMPROVING FISHING VESSELS. 
183 
square feet and a grate surface of 38.5 square feet, the working pressure being 80 pounds. 
On the official trial of this vessel a speed of 10.8 knots was obtained, the consumption 
of coal per twenty-four hours being between eight and nine tons.”* 
These steam-carriers have a capacity for cargo of from 3,000 to 3,500 “ trunks” of 
fish, each trunk or box holding from 80 to 90 pounds. The amount of ice carried to 
preserve these fish varies from 10 tons in winter to 25 or 35 tons in summer. 
The crew, as a rule, numbers twelve men, all told, four of these being in the 
engine-room, and eight on deck and in the galley. The deck gang is composed of the 
captain, mate, boatswain, and four seamen, while the cooking is done by one of the men, 
who is usually called a steward. 
2. ENGLISH STEAM-TRAWLERS. 
The Grimsby Steam Trawling Company was established in 1881, and in the 
beginning of the following year (1882) it commenced practical operations with two 
steamers. 
The pioneer vessel of this company, the Zodiac, was soon followed by the Aries, 
and so successful did these two vessels prove that in 1883 four other steamers had 
been added to the fleet. 
These are all iron, ketch-rigged, screw steamers, and dilfer chiefly in length, the 
more recently built vessels being a few feet longer than the others — the beam and 
depth remaining the same — and having a high quarter-deck. 
Description of the steam-trawler Zodiac. — The Zodiac has a flush deck, with a fore- 
castle under deck forward, aft of which is the forward fish-room. Between the two 
fish-rooms is the ice-house, provided with air-tight doors, in which is stored the ice 
that is used for preserving the cargo, and of which the vessel carries 8 tons in winter 
and 15 tons in summer. This ice-house is just abaft the mainmast. It extends from 
side to side and is about 7 feet fore and aft. Just abaft the after fish-room is the for- 
ward coal-bunker, which extends from deck to keelson and from side to side. This is 
located a little aft of amidships, and between it and the cabin, at the stern, are the 
boiler and the engine room. She has engines which are essentially the same as those 
supplied to other vessels of this class, the cylinders are compound surface-condensing, 
17 inches and 32 inches in diameter by 18 inches stroke ; cooling surface in condenser 
350 square feet; boiler, return tube pattern, 9 feet 8 inches diameter, and 8 feet 10 
inches long; heating surface 653 square feet ; grate surface, 19.25 square feet; work- 
ing pressure, 75 pounds; indicated horse-power, 182. The speed on trial was nearly 
9 knots; consumption of coal per twenty-four hours is about four tons. 
The Zodiac is 98 feet over all, 92 feet between perpendiculars, 20 feet (molded) 
beam, and 10 feet 6 inches deep. 
Details of construction of a steam-trawler. — The following are the details of dimen- 
sions, construction, etc., of one of the recent additions to the Grimsby Company’s 
fleet of steam-trawlers: Length between perpendiculars, 95 feet; beam, 20 feet; depth 
of hold, 10 feet 6 inches. Spars: Pole foremast, 70 feet long, 26 feet from eyes of 
rigging to truck, diameter at deck, 15 inches; pole mizzen-mast, 57 feet long, 21 feet 
feet from rigging to truck, 13 inches diameter at deck ; bowsprit, full length, 33 feet,
