surfboard leash is strap made of a rubbery plastic and nylon.

It is attatched at one end to your wrist by a velcro cuff and on the other end to your board with a string that ties into a fastener.

Leashes are used to prevent the loss of your board.

They are most useful in crowded areas where a lost board could be hazardous.

Also, being left boardless in big waves could put you in great danger.
