Problems solved by technology

For example, the design known as the Webber tail fin was disclosed as early as around 2004, but the Webber tail fin cannot effectively provide buoyancy for surfing or related sports, because it just slides on the surface of the wave without going deep below the surface of the wave, And there is no deterministic tip design that separates from the curve, which is what causes the tail fin to slide on the surface of the waves when there are waves

Embodiment Construction

[0024] Figure 1 to Figure 4 The fin 10 shown in has a base 11, a hydrofoil portion 12 extending from the base and an end 13 extending from the hydrofoil portion.

[0025] The bottom transitions to the hydrofoil section along the transition edge 16, at figure 1 and figure 2 , the transition edge is substantially parallel to the base edge 15 extending along the bottom base. exist image 3 and Figure 4 , the transition edge is not parallel to the bottom edge and is slightly curved in the plane of the bottom and end. Protruding from the base edge of the bottom are two protruding mounting lugs 14 which are arranged spaced apart and roughly in the shape of rectangular prisms of equal size. Equipped with such mounting lugs, the skeg can be installed in the skeg pocket of mainstream surf boats.

[0026] Between the hydrofoil portion and the end of the tail fin is an intermediate edge 17 . exist image 3 , the middle edge is angled, but in figure 1 , figure 2 and Figur...

Abstract

An integral foil for a surf craft fin comprising: a base portion extending in generally planar fashion between a base edge and a transitional edge spaced from the base edge; a foil portion extending in a generally planar fashion at an angle to the base portion from the transitional edge of the base portion to an intermediate edge spaced from the transitional edge; a tip portion extending in a generally planar fashion substantially parallel to the base portion from the intermediate edge of the foil portion; fastening means for fastening the surf craft fin to a surf craft having a floating plane; and wherein the base portion, foil portion and tip portion are of an integral and coextensive form.

Description

technical field [0001] The present invention relates to integrated hydrofoils for surf craft fins. The invention is particularly applicable to surfboard fins. But the present invention is not limited to this field of application, and can also be applied to other surfing boats. Background technique [0002] In order to be able to give an accurate description of the parts of the surfing boat, it is necessary to define the technical terms related to it, as follows: The surfing boat is roughly elongated in the direction of its intended movement, so there is a longitudinal axis and a The keel has a transverse axis at right angles, the two axes being slightly parallel to the surface of the water where the surfboat is expected to be carried. For convenience, the axis at right angles to both the elongated member and the transverse axis will be referred to simply as the mast axis hereinafter. The plane between the strip and the mast axis will be referred to as the longitudinal pla...
