A leash is the simplest piece of safety kit a surfer owns, keeping your board tethered to you so it does not wash away or become a hazard after a wipeout. This collection gathers surfboard leashes in a range of lengths and thicknesses, built to suit everything from small summer waves to bigger, more powerful surf.

Choosing the right leash for your board and conditions keeps you safe and avoids the frustration of losing your board or snapping a line in bigger surf. Below you will find leashes to match different board sizes and wave conditions, plus a guide to help you choose.

Why Do I Need a Surfboard Leash?

A leash keeps your board with you after a fall, which matters for two reasons. First, it saves you swimming in to retrieve a loose board, keeping you in the lineup and out of trouble. Second, and more importantly, a loose board is a danger to other surfers and swimmers, so a leash is a basic courtesy and safety measure in the water. For almost all surfing, a leash is essential.

How Do I Choose the Right Length?

As a general rule, your leash should be about the same length as your board, or slightly longer. A leash that is too short can pull the board back toward you after a fall, while one that is much too long adds drag and tangles. Measure your board and choose the nearest leash length, rounding up if you are between sizes.

What About Cord Thickness?

Leash cord thickness should match the conditions and your board.

• Thin, light leashes: less drag for small waves and high performance shortboarding
• Standard thickness: a good all round choice for everyday surf
• Thick, strong leashes: more strength for bigger, more powerful waves

In bigger surf the forces on a leash are much higher, so a thicker, stronger cord reduces the risk of it snapping when you need it most.

Leashes for Different Boards

Different boards suit different leashes. Shortboards use a standard ankle leash matched to the board length, longboards often use a longer leash worn at the calf or ankle so the line clears the board, and SUPs use dedicated, often coiled, leashes. Choosing a leash designed for your board type gives the best balance of safety and minimal interference.

What Makes a Good Leash?

Several details affect how a leash performs and lasts.

• A strong, moulded cuff: comfortable and secure around the ankle or calf
• A double swivel: to stop the leash tangling as you turn
• A quality urethane cord: that resists snapping and keeps its shape
• A padded, adjustable strap: for all day comfort
• A key pocket: on some cuffs for your car key

How to Choose Your Leash

Start with your board length and choose a leash to match, then pick a cord thickness for your conditions, thinner for small waves and performance, thicker for bigger, powerful surf. Match the leash type to your board, whether that is a shortboard, longboard or SUP. A comfortable cuff and a reliable swivel make everyday use much nicer.

How Do I Look After My Leash?

A little care keeps a leash safe and reliable.

• Rinse off salt and sand after surfing
• Dry it out of direct sunlight, which can weaken the cord over time
• Unwrap it rather than leaving it tightly coiled for long periods
• Check the cord, cuff, rail saver and swivels for wear before sessions
• Replace a leash showing cracks or fraying rather than risking a break

How Much Do Surfboard Leashes Cost?

Leashes are among the more affordable pieces of surf kit, with simple everyday leashes at the lower end and stronger, feature rich or big wave leashes costing a little more. A higher price usually buys a stronger cord, a better swivel and a more comfortable cuff. Because a leash is a safety item, buying a quality one and replacing it when worn is always worthwhile.

Frequently Asked Questions About Surfboard Leashes

What length leash do I need?

Choose a leash about the same length as your board, or slightly longer. Measure your board and pick the nearest size, rounding up if between lengths.

Does leash thickness matter?

Yes. Thinner leashes reduce drag for small waves and performance surfing, while thicker, stronger leashes resist the higher forces in bigger, powerful surf.

Where do I wear a surfboard leash?

Shortboarders usually wear it at the ankle, while longboarders often wear a longer leash at the calf so the line clears the board.

Do I always need a leash?

For almost all surfing, yes. It keeps your board with you and protects other surfers and swimmers from a loose board after a fall.

Why does a leash have a swivel?

A double swivel stops the leash twisting and tangling as you turn and manoeuvre, which keeps it from catching around your legs.

When should I replace my leash?

Replace it as soon as you see cracks, fraying or a worn cuff, rather than risking it snapping when you need it in bigger surf.
