A standing lug may be used with or without a boom; most working craft were boomless to allow more working space. The dipping lug never uses a boom. A dipping lug has to be moved to the leeward side of the mast when going about, so that the sail can take a good aerodynamic shape on the new tack. There are several methods of doing this – one of which is to simply lower the sail, manhandle the yard and sail to the other side of the mast and re-hoist. All the various methods are time and labour consuming. A standing lug can be left unaltered when tacking as it still sets reasonably well with the sail pressed against the mast. Some users (such as in the Royal Navy Montagu whaler) would still dip the yard of a standing lug (with a sharp, well timed downward pull on the leech at the moment when the wind is not filling the sail). Conversely many fishermen would always hoist a standing lug on the same side of the mast regardless of which tack they expected to be sailing on.
