context_page_description: Crosstrees are the two horizontal spars at the upper ends of the topmasts of sailing ships, used to anchor the shrouds from the topgallant mast. Similarly, they may be mounted at the upper end of the topgallant to anchor the shrouds from the royal mast. Similar transverse spars remain on steam ship and motor vessel masts to secure wire antennae or signal flag halyards.
