Hobie paddle clip or ot shock cord fasteners, two selfl sealing well nuts, your choice is shock it'd length and placement.. I'm asuming 5/8 mm. Shock cord is what you need but double check.. P.s. Keep the components of you Marage drive in good shape and you won't worry so much about your paddle. Paddling is for emergencies!!! Peddling is for Hands free use.
