Abstract

In one example, a watercraft includes a buoyant body in the form of a single piece structure sized and configured to support the weight of one or more users. The watercraft also includes a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body. The retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin includes an engagement portion that is engageable with a first portion of the body and with a second portion of the body. The retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.

First claim

What is claimed is:

1. A watercraft suitable for use in water sports and comprising:
a buoyant hollow plastic body in the form of a single piece structure sized and configured to support the weight of one or more users; and
a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body, wherein the retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin including an engagement portion that is engageable with a first portion of the body and with a second portion of the body, wherein the retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body.

2. The watercraft as recited in claim 1 , wherein the pin is integral with the retractable fin.

3. The watercraft as recited in claim 1 , wherein the body includes an upper surface that defines a deck.

4. The watercraft as recited in claim 1 , wherein the watercraft is one of a board, or a kayak.

5. The watercraft as recited in claim 1 , wherein the body defines a channel in which a portion of the pin resides, and the side surface of the pin contacts the bottom and/or sides of the channel.

6. The watercraft as recited in claim 1 , further comprising an additional retractable fin connected to the body.

7. A watercraft suitable for use in water sports and comprising:
a buoyant body in the form of a single piece structure sized and configured to support the weight of one or more users;
a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body, wherein the retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin including an engagement portion that is engageable with a first portion of the body and with a second portion of the body, wherein the retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body; and
a retainer connected to the body proximate the pin, the retainer configured and arranged to facilitate retention of the pin in position relative to the body,
wherein the watercraft is one of a paddleboard, or a kayak.

8. The watercraft as recited in claim 7 , wherein the body is a hollow plastic body.

9. The watercraft as recited in claim 7 , wherein the body includes an upper surface that defines a deck.

10. The watercraft as recited in claim 7 , wherein the body defines a channel in which a portion of the pin resides, and the side surface of the pin contacts the bottom and/or sides of the channel.

11. The watercraft as recited in claim 7 , further comprising an additional retractable fin connected to the body.

12. The watercraft as recited in claim 7 , wherein the retainer is connected to the body with one or more fasteners.

13. A paddleboard comprising:
a buoyant body in the form of a single piece structure sized and configured to support the weight of one or more users, the body including an upper surface that defines a deck;
a retractable fin connected to a pin that resides in a fixed location relative to the body, the pin including a side surface that is in contact with the body, wherein the retractable fin is rotatable about the pin between an extended position and a retracted position, and the retractable fin including an engagement portion that is engageable with a first portion of the body and with a second portion of the body, wherein the retractable fin assumes the extended position when the engagement portion is releasably retained by the first portion of the body, and the retractable fin assumes the retracted position when the engagement portion is releasably retained by the second portion of the body; and
a retainer connected to the body proximate the pin, the retainer configured and arranged to facilitate retention of the pin in position relative to the body.

14. The paddleboard as recited in claim 13 , wherein the retainer partly covers the pin.

15. The paddleboard as recited in claim 13 , wherein the retainer is connected to the body with one or more fasteners.

16. The paddleboard as recited in claim 13 , wherein the body defines a channel in which a portion of the pin resides, and the side surface of the pin contacts the bottom and/or sides of the channel.

17. The paddleboard as recited in claim 13 , further comprising an additional retractable fin connected to the body.

18. The paddleboard as recited in claim 13 , further comprising one or more tackoffs.

19. The watercraft as recited in claim 1 , wherein the engagement portion of the retractable fin comprises one or more pins.

20. The watercraft as recited in claim 1 , wherein the body defines a recess within which a portion of the retractable fin is disposed.

21. The watercraft as recited in claim 1 , wherein the body defines a recess, and the retractable fin extends part way out of the recess when the retractable fin is in the retracted position.

22. The watercraft as recited in claim 1 , wherein one or both of the first portion of the body and the second portion of the body are configured to releasably retain the engagement portion by way of a snap fit configuration.
