  • Patent number: 4996937
    Abstract: A small boat comprising a helmseat positioned at the center of the forward half of the boat, and a control stick for steering the boat positioned at the front of this helmseat. Since the helmseat is positioned at the center of the forward half of the boat, the driver is located approximately equidistant from the left and right gunwales, which makes it easier to steer the boat. In addition, a control stick is positioned to the front of the helmseat, and, because this control stick can be used to steer the boat and also to change the direction of the boat, the amount of space required to steer the boat is less than that required in a design wherein steering is performed by turning a circular steering wheel, such as with the prior art already described. This is effective particularly for a small boat moving at a high speed.
