Underwater wings for providing lift to boats
View Patent ↗The present invention relates generally to underwater wings for providing lift to boats. More particularly, the invention comprises an underwater wing that attaches to the hull or hulls of a pontoon or tri-toon boat. The purpose of the wing is to provide a designated amount of lift to reduce drag and improve performance of the watercraft. This is different from a traditional hydrofoil, which is designed to lift a boat completely out of the water.
1. A hydrofoil wing system for a pontoon boat comprising:
a wing comprising a length and a width;
a stabilizing mast having a vertical structure with a lower end and an upper end, said lower end attached to a center portion of said wing;
a stabilizing plate attached to said upper end of said stabilizing mast for connecting said wing via said stabilizing mast to a hull of said pontoon boat; and
wherein said pontoon boat is a pontoon boat having two pontoon hulls spaced apart by a width, and wherein said width of the wing spans at least seventy-five percent of said width between the pontoon hulls.
2. The hydrofoil wing system of claim 1 , wherein said width of the wing spans the entire width between said pontoon hulls.
3. A hydrofoil wing system for a pontoon boat comprising:
a wing comprising a length and a width, said width having a left terminal end and a right terminal end;
a first bracket positioned at said left terminal end for securing said wing to a first pontoon of said pontoon boat; and
a second bracket positioned at said right terminal end for securing said wing to a second pontoon of said pontoon boat; and
wherein said left terminal end of said wing is configured to slide vertically along said first bracket and said right terminal end of said wing is configured to slide vertically along said second bracket.
4. The hydrofoil wing system of claim 3 , wherein said wing further comprises at least one fence arranged parallel to the length of said wing.
5. The hydrofoil wing system of claim 3 , wherein said wing is constructed of aluminum.
6. The hydrofoil wing system of claim 3 , wherein said wing is constructed of fiberglass.
7. The hydrofoil wing of claim 3 , wherein said wing is constructed of carbon fiber.
8. The hydrofoil wing system of claim 3 , further comprising a hydraulic lift configured to raise and lower said wing.
9. The hydrofoil wing system of claim 3 , further comprising an electromechanical lift configured to raise and lower said wing.
10. A hydrofoil wing system for a pontoon boat comprising:
a first wing comprising a vertical portion and a horizontal portion and a curvature connecting said vertical and horizontal portions, such that said wing is substantially J-shaped;
a second wing comprising a vertical portion and a horizontal portion and a curvature connecting said vertical and horizontal portions, such that said wing is substantially J-shaped;
a first hydraulic mount attached to said vertical portion of said first wing, wherein said first hydraulic mount is configured to raise and lower said first wing relative to a water surface;
a second hydraulic mount attached to said vertical portion of said second wing, wherein said second hydraulic mount is configured to raise and lower said first wing relative to the water surface;
a first bracket connected to said first hydraulic mount for securing said first wing to a first pontoon of said pontoon boat; and
a second bracket connected to said second hydraulic mount for securing said second wing to a second pontoon of said pontoon boat.
11. The hydrofoil wing system of claim 10 , wherein said wings are constructed of aluminum.
12. The hydrofoil wing system of claim 10 , wherein said wings are constructed of fiberglass.
13. The hydrofoil wing system of claim 10 , wherein said wings are constructed of carbon fiber.
14. The hydrofoil wing system of claim 10 , wherein said first hydraulic mount and said second hydraulic mount are configured to be operated via electromechanical switch from a helm of said pontoon boat.
15. A hydrofoil wing system for a pontoon boat having a first pontoon, a second pontoon, and a deck supported by said first pontoon and said second pontoon, said hydrofoil wing system comprising:
a first wing having a first terminal end and a second terminal end, the first terminal end of said first wing attached to the first pontoon and configured to rotate about a longitudinal axis at a point of attachment to said first pontoon;
a second wing having a first terminal end and a second terminal end, the first terminal end of said second wing attached to the second pontoon and configured to rotate about a longitudinal axis at a point of attachment to said second pontoon;
an adjustable mount attached to an underside of said deck, wherein said adjustable mount is configured to adjust the height relative to the underside of said deck of at least one of the second terminal end of said first wing and the second terminal end of said second wing;
wherein said adjustable mount is configured to be operated via an electromechanical switch from a helm of said pontoon boat.
16. The hydrofoil wing system of claim 15 , wherein said adjustable mount is a first adjustable mount configured to adjust the height relative to the underside of said deck of the second terminal end of said first wing, and wherein said hydrofoil wing system further comprises:
a second adjustable mount attached to the underside of said deck, wherein said second adjustable mount is configured to adjust the height relative to the underside of said deck of the second terminal end of said second wing,
wherein said second adjustable mount is configured to be operated via the electromechanical switch from the helm of said pontoon boat.
