In one side of each fin there are holes to reeve large rope or small chain, which is to serve the purpose of hinges and to keep the fins in a vertical position in the water, and they are then fastened to part of a bower cable which is put overboard, and brought round the vessel's bottom, abreast of the foremast and then bowsed taut. A rope-guy from the outer end of each fin leads adt where the guy is fixed, to prevent the fin's traversing forward beyonf an angle of about ninety degrees from the vessel's side -- and there is a rope leading forward from the outer end of each fin to a block at the end of a topsail-yard, temporarily fixed on the deck a short distance abaft the stem, which latter rope leads inboard to a tackle or tiller, and thus the vessel is steered.
