A small vessel duly commanded, and employed to attend a larger one, to supply her with stores, to carry intelligence or volunteers and impressed men to receiving ships, &c. An enemy's ship captured by cutters or boats fitted out as tenders by men-of-war, but without any commission or authority from the admiralty, will not insure a prize to the benefit of the ship. The condemnation will be as a droit of admiralty, on the principle that an officer does not retain his commission for the purposes of prize on board another ship; but if captured by one of her boats, and brought to the ship, she is good prize, as with slaves. Tender is also a synonym of crank; thus, a spar may be tender.
