Advanced Hydrofoil Apparatus

Abstract

Hydrofoils are a device that is used to decrease the resistance of a water traveling apparatus. It does this by creating lift on its wings which pushes the apparatus off the surface of the water, to reduce friction. My patent pertains to hydrofoils that are attached onto boards for various water sports. These board sports include, but aren't limited to, surfing, stand up paddling, kitesurfing, kiteboarding, wakeboarding, wake surfing, and windsurfing.

Claims

1. A hydrofoil with a fuselage that is flexible from where the mast attaches, down to where it attaches to the tail. So that the fuselage can make a sinusoidal like motion through the water to generate speed.

2. Downward sloping fuselage or tail on hydrofoil.

3. A hydrofoil with a flexible back wing; where said wing's flexibility is along the general axis of the forward moving path of the hydrofoil, (which is parallel with the fuselage) or a flexible part trailing the tail wing with the same general axis of flexibility.

4. A hydrofoil meant for board sports that has both the front and back wing create lift.

5. A hydrofoil fuselage where the top (101a) or bottom (101b) portions of the fuselage are in a pointed shape, or in a rounded shape where the surface area between 101a and 101b has a lesser curve.

6. A clamp system that secures the hydrofoil to the board.

7. A hydrofoil meant for board sports that has more than one mast.

Description

DESCRIPTION OF DRAWINGS

[0009] FIG. 1 shows a hydrofoil for a board sport. 100 is the front wing. 101 is the fuselage. 101a is the top portion of the fuselage and 101b is the bottom portion as referred to in claim 3. 102 is the back wing. 103 is the mast.

[0010] FIG. 2 shows two cross sectional cuts of the fuselage. 101c is a fuselage where the top and bottom portion have a pointed shape. 101d is a fuselage where the top and bottom portion have a rounded shape.

[0011] FIG. 3 shows a hydrofoil with a downward curving fuselage (101e).

[0012] FIG. 4 shows the clamp system of attachment which connects the hydrofoil to the board. 105 is the attachment apparatus which is connected to the mast and rest of hydrofoil. It fits into the track (108) which is built into the board (107). 106 is the clamp mechanism that hooks around 105 and clamps it to the board to create a simple hydrofoil to board attachment system.
