Definitions
- the invention relates to a sailing boat comprising a boat ' s underwater ship provided with a keel and at least one rudder .
- Such a sailing boat is generally known in practice.
- the design of such a sailing boat is described, for example, in the book “ Principles of Yacht Design” by Lars Larsson and Rolf Eliasson, published in 1994, ISBN 0- 7136-3855-9.
- the known sailing boat is equipped with a keel at midship and one rudder or two rudders at the rear of the boat.
- the tasks of the keel and the rudder or the rudders are focused on keeping course and steering; one of these tasks is to limit the sideways drift of the sailing boat.
- the keel is provided with ballast, and preferably has a considerable draught in order to augment its effectiveness.
- the ballast is preferably located as far as possible away from the rump of the sailing boat, so that when the sailing boat leans over, a large torque is obtained to improve the boat's facility for lifting.
- the object of the invention is to provide a solution to these disadvantages and problems.
- a further object of the invention is to design the sailing boat such as to improve the sailing boat ' s travelling resistance, its facility for lifting, and at the same time to improve the sail-handling ability so that higher speeds can be realized.
- the sailing boat according to the invention is characterized in that, viewed in the boat's t t H H
- Toeing-in of the two bilge rudders can be realized simply by positioning the two bilge rudders out of square in relation to the longitudinal axis of the boat.
- each bilge rudder may optionally be designed such as to have a predetermined asymmetrical profile. It is moreover possible to vary the toe-in over the height of the bilge rudders, so that the sailing characteristics of the boat can adapt to the sailing conditions, and in particular to the current sailing speed of the boat .
- a favourable effect of the measures of the invention is further that they improve the course stability of the boat compared with that of a prior art sailing boat.
- Figure 2 shows the sailing boat according to the invention in a schematic front view
- Figure 3 shows the sailing boat according to the invention in a schematic view from below.
- reference number 1 indicates the sailing boat according to the invention. Said sailing boat
- 1 comprises a boat's underwater ship 2, as shown in Figure
- a keel 4 is located at the front as can be most clearly seen in Figure 1. Behind the keel 4 just passed midship, the boat 1 is at both sides provided with a bilge rudder 5', 5'' (see especially Figures 1 and 2) . Each bilge rudder 5', 5' ' is mounted near the bilge 6 of the boat, that is to say at the (rounded) transition between flat and freeboard. Each bilge rudder 5', 5 1 ' comprises preferably a skeg (not shown) and a pivoting rudder blade .
- the two bilge rudders 5', 5 1 ' are directed slightly inward, as is clearly shown in Figure 2.
- the two bilge rudders 5 ' , 5 I I are preferably toed-in, which means that the distance between the bilge rudders 5', 5*' at their front sides, i.e. the sides nearest the keel 4, is smaller than at their rear sides. This can be realized, for example, by positioning the two bilge rudders 5', 5'' out of square in relation to the longitudinal axis of the boat.
- Figure 1 shows that both bilge rudders 5 ' , 5 ' ' preferably also have a predetermined asymmetrical shape. Diverse variants on the exemplary embodiment discussed above and shown in the figures are conceivable. For example, it is possible to vary the toe-in over the height of the bilge rudders .
