Adjustable fin retention system and fin carriages

Abstract

Provided herein are fin retention systems adapted to releaseably attach a fin to a waterboard, comprising an outer carrier, an inner carrier, a fin carrier, and an end cap, wherein the fin retention system is adapted for movement in a generally for-and-aft direction, side to side angular rotation directional motion, and/or planar angle rotation directional motion.

1 . A fin retention system adapted to releaseably attach a fin to a waterboard, comprising:
 a board housing comprising an elongated cavity and configured to attach to the waterboard;   a fin housing comprising an elongated cavity configured to be releasably inserted within the elongated cavity of the board housing, the fin housing further comprising a plurality of inner grooves; and   a fin carriage configured to releaseably attach and secure the base of the fin, and wherein the fin carriage further comprises an outer ridge;   wherein the fin housing is secured to the board housing by an end cap, the positioning of the end cap enabling a for-and-aft movement of the fin housing within the board housing; and   wherein the fin carriage is configured to slide into the cavity of the fin housing, the outer ridge of the fin carriage aligning with one of the plurality of inner groves, the sliding angle providing a cant in the fin attached to the waterboard.   
     
     
         2 . A fin retention system adapted to releaseably attach a fin to a waterboard, comprising:
 a board housing comprising an elongated cavity and configured to attach to the waterboard;   a fin carriage configured to releasably attach and secure the base of the fin, and further configured to be inserted within the elongated cavity of the board housing; and   wherein the fin carriage is secured to the board housing by an end cap, the positioning of the end cap enabling a for-and-aft movement of the fin carriage within the board housing.   
     
     
         3 . A fin retention system adapted to releaseably attach a fin to a waterboard, comprising a board housing, a fin housing, a fin carrier, and an end cap,
 wherein the fin retention system is adapted for movement in a generally for-and-aft direction, side to side angular rotation directional motion, and/or planar angle rotation directional motion.   
     
     
         4 . The fin retention system of  claim 1 , wherein the waterboard is selected from the group comprising of: surfboard, paddleboard, skurfing board, windsurfing board, bodyboard, and kite surfing board. 
     
     
         5 . The fin retention system of  claim 1 , wherein the board housing is adapted to glass into the waterboard. 
     
     
         6 . The fin retention system of  claim 1 , wherein the outer carrier further comprises two threaded inserts. 
     
     
         7 . The fin retention system of  claim 1 , wherein the fin housing and/or fin carriage is adapted to rotate in plane to adjust to desired toe in/toe out. 
     
     
         8 . The fin retention system of  claim 1 , wherein the fin housing comprises grub screws that allows adjustment and lock down of the fin carriage. 
     
     
         9 . The fin retention system of  claim 1 , wherein the fin carriage is adapted to axially rotate to adjust fin angles. 
     
     
         10 . The fin retention system of  claim 1 , wherein the fin carriage is further adaptable to slide fore and aft within the fin housing and/or board housing. 
     
     
         11 . The fin retention system of  claim 1 , wherein the fin is locked into the fin carriage by grub screws. 
     
     
         12 . The fin retention system of  claim 1 , wherein the fin carriage comprises a cusp feature that allows for tightening at variable angles. 
     
     
         13 . A fin carriage adapted to configured to releaseably attach and secure the base of the fin, and wherein the fin carriage is configured to slide into a board housing attached to a waterboard. 
     
     
         14 . The fin carriage of  claim 13 , further comprising a fin housing having an elongated cavity, and wherein the fin carriage is configured to slide into the cavity of the fin housing. 
     
     
         15 . The fin carriage of  claim 13 , wherein the waterboard is selected from the group comprising of: surfboard, paddleboard, skurfing board, windsurfing board, bodyboard, and kite surfing board. 
     
     
         16 . The fin carriage of  claim 13 , wherein the fin housing and/or fin carriage is adapted to rotate in plane to adjust to desired toe in/toe out. 
     
     
         17 . The fin carriage of  claim 13 , wherein the fin housing comprises grub screws that allows adjustment and lock down of the fin carriage. 
     
     
         18 . The fin carriage of  claim 13 , wherein the fin carriage is adapted to axially rotate to adjust fin angles. 
     
     
         19 . The fin carriage of  claim 13 , wherein the fin carriage is further adaptable to slide fore and aft within the fin housing and/or board housing. 
     
     
         20 . The fin carriage of  claim 13 , wherein the fin is locked into the fin carriage by grub screws.
