                  that Deneys Reitz refers to it as an “11 tonner” belonging to Taylor, and one on which he
                  and his sons, John and Michael, enjoyed much happy fishing in False Bay. It would appear

                  that this boat co-existed in time with Voyager and Clewer. Born in 1860, Taylor left South
                  Africa in 1893 and so must have been an absentee boat-owner. Taylor subsequently had

                  another boat called Daphne built in England, which he describes as being twin-screwed and

                  capable of some 12 knots, suggesting a departure from the traditional fishing boat lines.
                  Whether this boat was moored in Kalk Bay is not known. The Skipper of Daphne, one Dick

                  Turpin, probably was afterwards Abe Bailey’s man in charge of Clewer. There is a picture
                  of a boat named Daphne, in the book by Stibbe and Moss, that was wrecked in the storm of

                  1978. She may have been Taylor’s Daphne - certainly the hull form is suggestive of that.


                  So we come to late thirties and very early forties and the four boats owned by Tromp van

                  Diggelen, the well known “strongman”. First was the Felicity (Fig. 3.28) which appears to
                  have been what we would term today a semi-planing hull. This seeks to marry the easily

                  driven features of the true displacement hull form with some of the characteristics of the

                  planing  hull  form  -  the  most  efficient  of  which,  of  course,  would  be  a  flat-bottomed
                  squarish  shape,  rather  like  a  tea  tray.  This  would  be  fine  in  perpetually  flat  water  but

                  disastrously impractical in any other sea condition.


                  So Felicity would have been capable of significantly higher speeds than both Voyager and
                  Clewer, but at a price, and incapable of the speeds of the true planing hull. This price is

                  reflected in the fact that at low speeds the semi-planing, or planing hull is not efficient as

                  regards propulsive effort required. This is because the “line form” of the planing hull drags
                  water behind it at any speed - at very low speeds a negligible amount, at speeds between 9

                  to 18 knots an expensive amount, and above 20 knots a relatively less expensive amount,
                  expressed in litres per mile.


                  This may seem to be a strange mixture of terms but the mile I refer to is the Sea Mile of

                  2000 yards, which is exactly one minute of arc of the surface of the earth, measured along
