Coleman and Sons built 3 pontoons around 1942. These were used to tie up to ships moored in Gage Roads during the war. Later, a yacht club obtained one and it was eventually sold to the Sandringham Hotel who intended to use it as a jetty for patrons to tie their boats to while in the hotel. After it sank, it was allowed to deteriorate and when the hotel changed hands it was decided to have the foreshore cleaned up and the pontoon was removed in 1980.
