Adjustable surfing fin

Abstract

According to some demonstrative embodiments of the present invention there is provided an apparatus for adjusting the flexibility of a fin of a waterborne vessel comprising at least one movable and/or rotatable component adapted to be positioned in one of at least two different positions, a first position and a second position, wherein when said component is positioned at said first position, said fin exhibits a first degree of flexibility, and when said component is positioned at said second position, said fin exhibits a second degree of flexibility, wherein said first degree of flexibility is greater then said second degree of flexibility.

1 . An apparatus for adjusting the flexibility of a fin of a waterborne vessel comprising at least one movable and/or rotatable component adapted to be positioned in one of at least two different positions, a first position and a second position, wherein when said component is positioned at said first position, said fin exhibits a first degree of flexibility, and when said component is positioned at said second position, said fin exhibits a second degree of flexibility, wherein said first degree of flexibility is greater then said second degree of flexibility. 
     
     
         2 . The apparatus of  claim 1 , wherein said waterborne vessel is selected from the group consisting of: surfboard; kitesurf board; windsurf board; boogie board; paddle board; wave board; wake board; kayak; canoe; sailing boat; waterski, jetski. 
     
     
         3 . The apparatus of  claim 1 , wherein said component comprises a disc comprising a plurality of rods and a plurality of slots;
 a screwing element; and   wherein said disc may be rotated to various positions and reversibly locked in place via said plurality of slots and wherein rotating said disc to various positions provides a different degree of flexibility to said fin.   
     
     
         4 . The apparatus of  claim 3 , having means for rotating said disc by hand. 
     
     
         5 . The apparatus of  claim 4  having means for rotating said disc by means of a screw driver. 
     
     
         6 . The apparatus of  claim 1 , wherein said component comprises a movable lever adapted to be positioned in one of at least two different positions, a first horizontal position and a second vertical position, wherein when said component is positioned at said first horizontal position, said fin exhibits a first degree of flexibility, and when said component is positioned at said second vertical position, said fin exhibits a second degree of flexibility, wherein said first degree of flexibility is greater then said second degree of flexibility 
     
     
         7 . A wearable adjustment device adapted to enable the rotation of a disc contained within a fin and to provide a different degree of flexibility to said fin. 
     
     
         8 . The device of  claim 7 , wherein said waterborne vessel is selected from the group consisting of: surfboard; kitesurf board; windsurf board; boogie board; paddle board; wave board; wake board; kayak; canoe; sailing boat; waterski, jetski. 
     
     
         9 . The wearable adjustment device of  claim 8 , wherein said device is a ring.
