Abstract

A boat for operation in water has a hull longitudinally extending between a bow and a stern and laterally extending between a port side and a starboard side, a hydrofoil suspended from the hull, wherein as the boat moves through the water the hydrofoil is configured to create a lifting force for lifting the hull upwardly out of water, and a weed deflector located between the hydrofoil and the bow, wherein the weed deflector is configured to deflect weeds away from the hydrofoil.

First claim

What is claimed is:

1 . A boat for operation in water, the boat comprising:
a hull longitudinally extending between a bow and a stern and laterally extending between a port side and a starboard side, a hydrofoil suspended from the hull, wherein as the boat moves through the water the hydrofoil is configured to create a lifting force for lifting the hull upwardly out of the water, and a weed deflector located between the hydrofoil and the bow, wherein the weed deflector is configured to deflect weeds away from the hydrofoil.

2 . The boat according to claim 1 , wherein the hydrofoil comprises a lifting member configured to create the lifting force, the lifting member having a port wing which laterally extends relative to the port side of the hull and a starboard wing which is opposite the port wing and which laterally extends relative to the starboard side of the hull.

3 . The boat according to claim 2 , wherein the lifting member comprises a forward edge which is curved from the port wing to the starboard wing.

4 . The boat according to claim 2 , wherein the lifting member comprises a forward edge which is straight from the port wing to the starboard wing.

5 . The boat according to claim 2 , wherein the weed deflector has a first end coupled to the bow, a second end which is opposite the first end, and a body which extends downwardly from the hull towards the lifting member.

6 . The boat according to claim 5 , wherein the weed deflector is a first weed deflector, and further comprising a second weed deflector located between the hydrofoil and the bow, wherein the second weed deflector is configured to deflect weeds away from the hydrofoil, and further wherein the second weed deflector has a first end coupled to the bow, a second end which is opposite the first end, and a body which extends downwardly from the hull towards the lifting member.

7 . The boat according to claim 5 , wherein the body is a straight member extending from the first end to the second end.

8 . The boat according to claim 7 , wherein the second end is coupled to the lifting member.

9 . The boat according to claim 7 , wherein the second end is separate from the lifting member.

10 . The boat according to claim 5 , wherein the body is a curved member extending downwardly from the hull and then rearwardly to the second end.

11 . The boat according to claim 10 , wherein the second end is coupled to the lifting member.

12 . The boat according to claim 10 , wherein the second end is separate from the lifting member.

13 . The boat according to claim 2 , wherein the hydrofoil further comprises a strut which couples the lifting member to the hull.

14 . The boat according to claim 13 , wherein the weed deflector has a first end coupled to the bow, a second end which is opposite the first end, and a body which extends downwardly from the hull towards the lifting member.

15 . The boat according to claim 14 , wherein the second end of the weed deflector is coupled to a forward edge of the lifting member.

16 . The boat according to claim 14 , wherein the second end of the weed deflector is coupled to the strut above the lifting member.

17 . The boat according to claim 16 , wherein the second end of the weed deflector is coupled to a bottom surface of the lifting member.

18 . The boat according to claim 13 , wherein the strut has a first end coupled to the hull, a second end which is opposite the first end and is coupled to the lifting member, and a body which extends from the first end to the second end.

19 . The boat according to claim 18 , wherein the strut is a first strut, and further comprising a second strut having a first end coupled to the hull, a second end which is opposite the first end and is coupled to the lifting member, and a body which extends from the first end to the second end.

20 . The boat according to claim 18 , further comprising a propulsor coupled to the second end of the strut.

21 . The boat according to claim 1 , wherein the hydrofoil is movable relative to the hull into and between an extended position and a retracted position.

22 . The boat according to claim 1 , wherein the weed deflector is movable relative to the hull into and between an extended position and a retracted position.

23 . The boat according to claim 2 , wherein the weed deflector is between the hydrofoil and the bow.

24 . The boat according to claim 2 , wherein the weed deflector is between the port wing and the starboard wing.
