The lowest section of mast nearest the bow is termed the foremast, the middle section the fore topmast and the uppermost the fore topgallant mast. This bears a correlation to the names to the three spars forming the centre or main mast, namely the main, the top mast and the topgallant mast. Those of the third or mizzen mast are the mizzen, mizzen topmast and mizzen topgallant mast. A fourth mast would be termed the jigger, and a fifth one after that the jigger mast.
