There was a brief break in the scudding clouds, and the watery light played down along Undine's gun ports to her clean sheathing as she rolled uneasily in the swell. Best Anglesey copper. Stout enough for anything. Bolitho recalled what her previous captain, Stewart, had confided. In a fierce skirmish off Ushant he had been raked by heavy guns from a French seventy-four. Undine had taken four balls right on her waterline. She had been fortunate to reach England afloat. Frigates were meant for speed and hit-and-run fighting, not for matching metal with a line of battleship. Bolitho knew from his own grim experience what that could do to so graceful a hull.
Stewart had added that despite careful supervision he was still unsure as to the perfection of the repairs. With the copper replaced, it took more than internal inspection to discover the true value of a dockyard's overhaul. Copper protected the hull from many sorts of weed and clinging growth which could slow a ship to a painful crawl. But behind it could lurk every captain's real enemy, rot. Rot which could change a perfect hull into a ripe, treacherous trap for the unwary. Admiral Kempenfelt's own flagship, the Royal George, had heeled over and sunk right here in Portsmouth just two years ago, with the loss of hundreds of lives. It was said that her bottom had fallen clean away with rot. If it could happen to a lofty first-rate at anchor, it would do worse to a frigate.
