Means for removably installing fins on a board for use in water sports

A board for use in water sports comprising:

• a fin and a deck, the fin being removably secured to the deck by a fin mount secured within a cavity in the deck;
• the fin mount being configured to receive the base part of the fin in a releasably secure fit;
• a butt end of the base of the fin engaging with the mount in a releasable and rotatable fit;
• the distal end part of the fin engaging with a cam that forms part of the mount, the cam having a contact area for application of downward finger pressure;
• the fin, when its butt end part is engaged rotatably in the mount, being rotatable to a position where the distal end part engages with the cam to lock the fin in the mount;
• and
• the cam including a pivoting member biased by a biasing member to a position to engage with the distal end of the fin, as the fin is rotated to a position within the mount, to lock the distal end of the fin to the pivoting member to secure the fin to the mount and where downward finger pressure applied to the contact area of the cam disengages the pivoting member from the distal end of the fin so that the fin can be removed from the mount, the pivoting member being configured to pivot between a first locking position and a second unlocking position, the pivoting member being driven to the locking position by the force of the biasing member, the biasing member being a spring.
