Abstract
A paddle for use in watersports is provided with shaft halves and blades at the end of each shaft half with a selectable offset angle between the blades. A joint connecting the shaft halves may include an interlocking coupling that maintains the offset angle of the blades, and that may allow a change in the offset angle of the blades. A biasing member may hold the interlocking coupling in the use configuration. The shaft halves may be moved axially apart to change the offset angle of the blades. All mechanisms for switching the interlocking coupling between the use configuration and the selection configuration may be located within the shaft halves. A retaining clip may be coupled between the first and second shaft halves to allow the selection configuration while preventing disassembly of the first and second shaft halves. A disassembly control can be provided independently of the angle selection.
