Slip :: Slip (n.) The motion of the center of resistance of the float of a paddle wheel, or the blade of an oar, through the water horozontally, or the difference between a vessel's actual speed and the speed which she would have if the propelling instrument acted upon a solid; also, the velocity, relatively to still water, of the backward current of water produced by the propeller..

Carronade :: Carronade (n.) A kind of short cannon, formerly in use, designed to throw a large projectile with small velocity, used for the purpose of breaking or smashing in, rather than piercing, the object aimed at, as the side of a ship.
