No space which is required for working the anchors or the boats or for purposes of navigation is to be included, and no deck space is to be measured over which the first, second or third class passengers require to pass in going from their quarters to the closets or to the airing spaces set apart for their use. The aggregate length of all the spaces so measured for unberthed passengers on any deck, whether below or above the weather deck, shall not exceed the registered length of the vessel.
