BALANCE, To. To contract a sail into a narrower compass;—this is peculiar to the mizen of a ship, and to the main-sail of those vessels wherein it is extended by a boom. The operation of balancing the mizen is performed by lowering the yard or gaff a little, then rolling up a small portion of the sail at the peak or upper corner, and lashing it about one-fifth down towards the mast. A boom main-sail is balanced by rolling up a portion of the clew, or lower aftermost corner, and fastening it strongly to the boom.—N.B. It is requisite in both cases to wrap a piece of old canvas round the sail, under the lashing, to prevent its being fretted by the latter.
