SEAM. The sewing together of two edges of canvas, which should have about 110 stitches in every yard of length. Also, the identical Anglo-Saxon word for a horse-load of 8 bushels, and much looked to in carrying fresh fish from the coast. Also, the opening between the edges of the planks in the decks and sides of a ship; these are filled with a quantity of oakum and pitch, to prevent the entrance of water. (See [Caulking].)

SEAMAN. This is a term seldom bestowed among seafaring men upon their associates, unless they are known to be pre-eminent in every duty of the thorough-paced tar; one who never issues a command which he is not competent to execute himself, and is deemed an authority on every matter relating to sea-craft.—The able seaman is the seafaring man who knows all the duties of common seamanship, as to rig, steer, reef, furl, take the lead, and implicitly carry out the orders given, in a seamanlike manner. His rating is A.B.; pay in the navy, 24s. to 27s. per month.—The ordinary seaman is less qualified; does not take the weather-helm, the earing, or lead; pay about 21s. to 23s. per month.—The landsman is still less qualified.

SEAMAN'S DISGRACE. A foul anchor.

SEAMANSHIP. The noble practical art of rigging and working a ship, and performing with effect all her various evolutions at sea.

SEAMAN'S WAGES. A proper object of the admiralty jurisdiction.
