## Abstract

Implementations of paddles may include at least one paddle blade coupled to a shaft, a sleeve coupled over the shaft, the sleeve including a helical opening, a locator pin coupled to the shaft and extending through the helical opening, and a first handle fixedly coupled to the sleeve. The paddle blade may be configured to rotate from a first position corresponding to the locator pin positioned at a first location in the helical opening to a second position corresponding to the locator pin positioned at a second location in the helical opening.

## Claims

### Claim 1

A paddle comprising:
at least one paddle blade coupled to a shaft;
a sleeve coupled over the shaft, the sleeve comprising a helical opening;
a locator pin coupled to the shaft and extending through the helical opening; and
a first handle fixedly coupled to the sleeve;
wherein the paddle blade is configured to rotate from a first position corresponding to the locator pin positioned at a first location in the helical opening to a second position corresponding to the locator pin positioned at a second location in the helical opening.

### Claim 2 (depends on 1)

The paddle of claim 1, further comprising a second handle coupled around the shaft.

### Claim 3 (depends on 2)

The paddle of claim 2, wherein the second handle is fully rotatable about the shaft.

### Claim 4 (depends on 1)

The paddle of claim 1, wherein the first handle is configured to rotate a predetermined number of degrees not more than 90 degrees.

### Claim 5 (depends on 1)

The paddle of claim 1, wherein the helical opening comprises a first locking section at a first end of the helical opening and a second locking section at a second end of the helical opening.

### Claim 6 (depends on 1)

The paddle of claim 1, wherein the locator pin comprises a bearing.

### Claim 7 (depends on 1)

The paddle of claim 1, wherein the sleeve further comprises a second helical opening.

### Claim 8 (depends on 1)

The paddle of claim 1, wherein a movement of the first handle along a length of the shaft is configured to be adjustably restricted.

### Claim 9 (depends on 1)

The paddle of claim 1, wherein the sleeve is configured to slide along a length of the shaft a predetermined distance not more than a length of the helical opening from a first end of the helical opening to a second end of the helical opening.

### Claim 10

A paddle comprising:
a first paddle blade coupled to a first end of a shaft;
a second paddle blade coupled to a second end of the shaft opposite the first end;
a sleeve coupled over the shaft, the sleeve comprising a helical opening;
a locator pin coupled to the shaft and extending through the helical opening;
a first handle coupled to the shaft and fixedly coupled to the sleeve; and
a second handle coupled to shaft;
wherein the sleeve is configured to slide along a length of the shaft from a first position to a second position; and
wherein the shaft is configured to rotate relative to the sleeve when the sleeve slides along the length of the shaft from the first position to the second position.

### Claim 11 (depends on 10)

The paddle of claim 10, wherein the second handle is configured to fully rotate about the shaft.

### Claim 12 (depends on 10)

The paddle of claim 10, wherein the helical opening comprises a first non-helical end and a second non-helical end.

### Claim 13 (depends on 10)

The paddle of claim 10, wherein the helical opening extends not more than 90 degrees.

### Claim 14 (depends on 10)

The paddle of claim 10, wherein the first handle and the second handle comprise compressible material.

### Claim 15

A paddle comprising:
a paddle blade coupled to a first end of a shaft;
a sleeve coupled over the shaft, the sleeve comprising a helical opening;
a locator pin coupled to the shaft and extending through the helical opening;
a spring coupled over the shaft between the sleeve and the paddle blade; and
a first handle fixedly coupled to the sleeve.

### Claim 16 (depends on 15)

The paddle of claim 15, wherein the paddle is a single bladed paddle.

### Claim 17 (depends on 15)

The paddle of claim 15, wherein the shaft is configured to rotate relative to the sleeve a predetermined number of degrees not more than 90 degrees.

### Claim 18 (depends on 15)

The paddle of claim 15, wherein the locator pin comprises a bearing.

### Claim 19 (depends on 15)

The paddle of claim 15, wherein the first handle is slidably coupled to the shaft.

### Claim 20 (depends on 15)

The paddle of claim 15, wherein the spring is configured to compress during a portion of a paddle stroke.
