The gangway is the connection between the land and any floating structure and takes up the difference between high and low tide. Being a stiff construction, the fastening points need to deal with the motion of a floating structure on one hand, and a fixed land fundament in the other, as well as tidal differences. SF Marina supplies gangways in galvanized steel and in aluminium. Lengths range from 4-meters up to 30-meters. Widths range from 1,2-meters to 10-meters. Gangway shall be stable to go on, the default width is 1.2-meter. A 4-meter gangway can function without railing but 6-meter and 8-meter times country should have one or two rails. Custom designs are available.
