                  chine” - that is a sharp corner between the side and the bottom, but Mr. Gerber modified
                  this design by placing inserts in the mould which gave her a rounded chine shape. This

                  would have given a softer ride but at the expense of some speed and she might well be
                  regarded  as  a  semi-planing  hull.  She  carried  three  and  a  half  tons  of  fuel  giving  her  a

                  cruising range of some 850 miles.


                  When completed, she was shipped to Matadi on the Congo River, and then sailed down the

                  coast arriving at RCYC in the summer of 1957. The following year she relocated to Kalk
                  Bay, taking a mooring between the old wooden jetty and the beach. (Fig. 3.43). Here she

                  stayed for about three years before moving to Simon’s Town, giving her mooring to the
                  newly launched Speranza. After Gerber’s death she was bought in 1983 by Fritz Palthe and

                  moored  in  Hout  Bay.  In  1990  she  was  bought  by  Ian  Hirschson  and  has  recently  been

                  completely overhauled and is in tip-top condition, with the same RR engines, and berthed
                  in Grainger Bay, Cape Town. “Hoppy” James, who skippered Bebe Grande for Jack Gerber

                  from 1957 onwards, has remained her skipper ever since and is still with her.


                  Speranza was, I think, the first monohedron-type planing boat in South Africa. This design

                  type by an Italian, Renato Levy, maintained a constant “deadrise” angle between the keel
                  and the chines, or bottom corners to either side, for most of the length of the boat to the

                  stern, or back of the boat. This was in contrast with the so-called “warped hull” form where
                  the angle of the bottom changes from the sharp angles at the bow to an almost flat section

                  aft.  While  the  warped  hull  with  its  relatively  large  almost  flat  planing  section  is  more

                  efficient, the constant angle of the Levy design gave a softer ride. This well-known boat
                  which is still in regular use, but not in its original form - having undergone some changes in

                  superstructure - was built by the Hare Brothers at their Mowbray brickfield, now apartment
                  blocks, in 1959/60, and launched on 18 May 1961. Speed trials in 1964, three years after

                  launching, gave speeds of 24 knots, and I suspect that she may well have been quicker just
                  after launching, as wooden boats do add weight with time. (Fig. 3. 44).
