This is the new 2017 Hobie Mirage Drive 180 Turbo Fin V2 upgrade kit. Upgrade your standard 180 fins with the new 180 Turbo Fin Kit.
The new “V2” version removes the adjustment thumb screw from the clew attachment. The fin adjustment is now a screw at the mast head. The boom is modified to accept the new fin with a simple clevis pin and ring connection.
