Shark Ship C M Kornbluth
IT WAS THE SPRING SWARMING of the plankton; every man and woman and most of the children aboard Grenville’s Convoy had a job to do. As the seventy-five gigantic sailing ships plowed their two degrees of the South Atlantic, the fluid that foamed beneath their cutwaters seethed also with life. In the few weeks of the swarming, in the few meters of surface water where sunlight penetrated in sufficient strength to trigger photosynthesis, microscopic spores burst into microscopic plants, were devoured by minute animals which in turn were swept into the maws of barely visible sea monsters almost a tenth of an inch from head to tail; these in turn were fiercely pursued and gobbled in shoals by the fierce little brit, the tiny herring and shrimp that could turn a hundred miles of green water to molten silver before your eyes.
Through the silver ocean of the swarming the Convoy scudded and
tacked in great controlled zigs and zags, reaping the silver of the sea in the endlessly reeling bronze nets each ship payed out behind.
The Commodore on Grenvllle did not sleep during the swarming; he and his staff dispatched cutters to scout the swarms, hung on the meteorologists’ words, digested the endless reports from the scout vessels, and toiled through the night to prepare the dawn signal. The mainmast flags might tell the captains “Convoy course five degrees right,” or “Two degrees left,” or only “Convoy course: no change.” On those dawn signals depended the life for the next six months of the million and a quarter souls of the Convoy. It had not happened often, but it had happened that a succession of blunders reduced a Convoy’s harvest below the minimum necessary to sustain life. Derelicts were sometimes sighted and salvaged from such convoys; strong-stomached men and women were needed for the first boarding and clearing away of human debris. Cannibalism occurred, an obscene thing one had nightmares about.
The seventy-five captains had their own particular purgatory to endure throughout the harvest, the Sail-Seine Equation. It was their job to balance the push on the sails and the drag of the ballooning seines so that push exceeded drag by just the number of pounds that would keep the ship on course and in station, given every conceivable variation of wind force and direction, temperature of water, consistency of brit, and smoothness of hull. Once the catch was salted down it was customary for the captains to converge on Grenville for a roaring feast by way of letdown.
Rank had its privileges. There was no such relief for the captains’ Net Officers or their underlings in Operations and Maintenance, or for their Food Officers, under whom served the Processing and Stowage people. They merely worked, streaming the nets twenty-four hours a day, keeping them bellied out with lines from mast and outriding gigs, keeping them spooling over the great drum amidships, tending the blades that had to scrape the brit from the nets without damaging the nets, repairing the damage when it did occur; and without interruption of the harvest, flash-cooking the part of the harvest to be cooked, drying the part to be dried, pressing oil from the harvest as required, and stowing what was cooked and dried and pressed where it would not spoil, where it would not alter the trim of the ship, where it would not be pilfered by children. This went on for
weeks after the silver had gone thin and patchy against the green, and after the silver had altogether vanished.
The routines of many were not changed at all by the swarming season. The blacksmiths, the sailmakers, the carpenters, the water-tenders, to a degree the storekeepers, functioned as before, tending to the fabric of the ship, renewing, replacing, reworking. The ships were things of brass, bronze, and unrusting steel. Phosphor-bronze strands were woven into net, lines, and cables; cordage, masts, and hull were metal; all were inspected daily by the First Officer and his men and women for the smallest pinhead of corrosion. The smallest pinhead of corrosion could spread; it could send a ship to the bottom before it had done spreading, as the chaplains were fond of reminding worshippers when the ships rigged for church on Sundays. To keep the hellish red1 of iron rust and the sinister blue of copper rust from invading, the squads of oilers were always on the move, with oil distilled from the catch. The sails and the clothes alone could not be preserved; they wore out. It was for this that the felting machines down below chopped wornout sails and clothing into new fibers and twisted and rolled them with kelp and with glue from the catch into new felt for new sails and clothing.
