“…rousing on the sheets of a sail. Spinnaker takedown from hell?

Conchy say: “Rooz'n 'de sletch!”

“ROUZE, to raise game from its harbour (hunting.) To haul in that part of a hawser which lies slake in the water. (sea.)”
[From: An Universal Etymological Dictionary English Dictionary, (London, 1731)]

“ROUSSING, the act of pulling together upon a cable, hauser, &c. without the assistance of tackles, capsterns, or other mechanical powers. It is particularly used in the exercise of removing a ship from one place to another, by means of ropes and anchors, See the article Warping.”
[Falconer, William, An Universal Dictionary of the Marine, (London: T. Cadell, 1769)]

“Rouse-In, to, to haul in any slack cable, or *slatch which may lie on the bottom, when a vessel lies to a single anchor. The reason for rousing in such slack cable is that otherwise it might foul the anchor by becoming twisted round the shank or stock as the ship swings to wind or tide.”
[The Oxford Companion to Ships & the Sea, (London: Oxford U. Press, 1976, p.725)]

“SLATCH of Fair-Weather [sea phrase] is when there comes an interval of fair weather, after long foul-weather.”
[Universal Etymological]

“SLATCH, is generally applied to the period of a transitory breeze of wind, or the length of its duration.”
[Universal Marine]

“ROUSTABOUTS Circus jargon for the unskilled laborers and workmen on the show. Roustabouts are those who travel with the circus and do not include the laborers who are employed each day locally to augment the crew.

Signed on as being generally useful, the roustabouts perform duties such as setting up tents, carrying props in and out of the ring and helping to clean up after the animals during performance.”
[Ogden, Tom, Two Hundred Years of the American Circus, (New York: Tom Ogden, 1993, p.307)]

IE: They “take up the slack.” Same generalist definition for the oil patch except it's a proper job title now.
