Surfer(Specially designed attachments to crew boats, larger vessels and offshore structures, often referred to as "surfers", are sometimes used. These may take the form of a purpose built device on the bow of a crew boat ('male' section), designed to fit into a receptacle frame or structure on a larger vessel or offshore structure ('female' section). The crew boat or smaller vessel approaches and docks with the "surfer" receptacle allowing personnel to step safely across. ixtra)
