Abstract
Tool-less detachable fins and fin assemblies for watersport boards (e.g, surfboards, wake boards, windsurfing boards, kite boards, stand-up paddle boards and the like) are disclosed. Some embodiments are directed toward detachable fin assemblies which include a fin having a mounting tang defining at least one detent recess in an edge thereof, and a fin box defining an elongate mounting channel for receiving the mounting tang of the fin. The fin box includes at least one spring-biased ball detent assembly having a ball detent positioned so as to engage the at least one detent recess when the mounting tang is positioned within the mounting channel to thereby removably fix the fin to the fin box. The fin box may include at least one threaded aperture for receiving a ball detent assembly therein.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
