• 1849, James Peake, Rudiments of Naval Architecture; or, an Exposition of the Elementary Principles of the Science and the Practical Application to Naval Construction; Compiled for the Use of Beginners, London: John Weale, page 17:

  […] the area contained between the curve bounding the representative area for the load displacement, and the curve bounding the representative area for the light displacement, will be a representative area of the sum of the weights to be received on board, and point out their position to bring the ship from the light line of floatation, or the line of immersion due to the weight of the hull when completed in every respect, to that of the deepest immersion, or the proposed load-water line of the constructor […]

• 1860, G. Moorsom, “On the New Tonnage-Law, as Established in the Merchant-Shipping Act of 1854”, in E. J. Reed, editor, Transactions of the Institution of Naval Architects, volume 1, London, page 137:

  It is seen […] that the weights due to 1 inch immersion at the two different draughts of load and light lines vary on an average on several vessels to the extent only of about 10 per cent; and, therefore, that the weight which would sink a vessel 1 inch when she is floating at her load-line would sink her 1/10 of an inch more when floating at her light line.

• 1882, W. H. White, The Manual of Naval Architecture, 2nd edition, London: John Murray, page 61:

  Starting from this assumption, Mr. Waymouth proposes to ascertain the light-line to which a ship would be immersed when equipped for sea, but without cargo on board. For sailing vessels, no consumable stores are to be on board; for steamers, the engines are to be complete, and the water in the boilers, but no coals are to be on board when the light-line is ascertained.
