The devices clamp about skateboard sides between the two sets of wheels. One version has a hook ended rod that grips about a board side and another end that attaches by a padlock to a second rod which hooks about another board side. The first rod end has through holes that insert into a cylinder end of the second rod. The further one rod is inserted into the second cylindrical rod end, the closer the spacing between the hooks. A padlock in the through-holes connect the rods. Another version has a padlock in the second cylindrical rod where grooves on the first rod end are locked in place. Another version has a perpendicular extension bracket that wraps about one surfboard or sailboard fin. Another version uses a top flat plate that hingedly connects to a curved bottom plate. Opposite ends of the plates have matching through-holes for a padlock. Another version has side-by-side holes in both plates to accommodate different board widths. A cable connects the devices to a pole or bikerack. ## Claims ### Claim 1 A locking device in combination with a recreation board, the recreation board chosen from one of a surfboard and sailboard, the device comprises: a top planar plate having a first end and a second end, the second end having a through-hole, the top plate overlying an upper surface of the recreation board having fins with first and second tapered sides, the recreation board having a narrow width end adjacent to the fins and a wide width middle; a hinge having one side connected to the first end of the top plate adjacent the first tapered side of the recreation board in front of the fins; a lower curved plate having a first end and a second end, the first end of the lower curved plate connected to a second side of the hinge, the second end of the lower curved plate having a through-hole, wherein the top plate and the lower curved plate rotate relative to the hinge and the through-holes of each plate match together, the lower curved plate abutting against a lower curved surface and the first and the second tapered sides of the recreation board; and a padlock for connecting through the top plate through-hole and the lower curved plate through-hole adjacent the second tapered side, the top plate and the lower curved plate being positioned between the narrow width end and the wide width middle of the recreation board. ### Claim 2 (depends on 1) The combination of claim 1, further comprising: a first cushion sleeve for wrapping about the top plate; and the second cushion sleeve for wrapping about the lower curved plate. ### Claim 3 (depends on 1) The combination of claim 1, further comprising: a cable having first and second loop ends, the first end attached to the top plate. ### Claim 4 A locking device in combination with a recreation board, the recreation board chosen from one of a surfboard and sailboat, the device comprises: a top straight rod having a first end and a second end, the second end having a through-hole, the top rod overlying an upper flat surface of the recreation board having fins with first and second tapered sides, the recreation board having a narrow width end adjacent to the fins and a wide width middle; a hinge having one side connected to the first end of the top rod adjacent the first tapered side of the recreation board in front of the fins; a lower curved rod having a first end and a second end, the first end of the lower curved rod connected to a second side of the hinge, the second end of the lower curved rod having a through-hole, wherein the top rod and the lower curved rod rotate relative to the hinge and the through-holes of each rod match together, the lower curved rod abutting against a lower curved surface and the first and the second tapered sides of the recreation board; and a padlock for connecting through the top rod through-hole and the lower curved rod through-hole adjacent the second tapered side, the top rod and the lower curved rod being positioned between the narrow width end and the wide width middle of the recreation board. ### Claim 5 (depends on 4) The combination of claim 4, further comprising: a first cushion sleeve for wrapping about the top rod; and a second cushion sleeve for wrapping about the lower curved rod. ### Claim 6 (depends on 4) The combination of claim 4, further comprising: a cable having and second loop ends, the first loop end attached to the top rod.
