Do Sailors Actually Get Slipped Discs? What's Really Happening With Your Back on the Water

A friend of mine - sharp as a tack, works in finance in London, has been sailing since she was eight, told me recently that she had a slipped disc from sailing.

She was matter-of-fact about it. 'Yeah, my back's been at me for months. Slipped disc from hiking, I think.' She'd googled it, it seemed to fit, and she'd essentially written off her back as a permanent occupational hazard of being a competitive sailor.

Here's the thing: she almost certainly didn't have a slipped disc. But she also wasn't wrong that sailing had something to do with it. And the gap between those two things, between what sailors believe is happening in their bodies and what is actually happening, is where a lot of unnecessary pain, missed regattas, and poor rehabilitation decisions live.

So let's talk about what's actually going on.

What Is a 'Slipped Disc' and Do Sailors Actually Get Them?

The term 'slipped disc' is one of the most common and most misleading pieces of medical vocabulary in general circulation. Discs, the cushioning structures between the vertebrae of your spine, don't actually slip. They can bulge, herniate, or degenerate, but the image of a disc sliding sideways out of place like a hockey puck is not really how it works.

Disc herniations, where the outer casing of a disc develops a tear and some of the inner material pushes outward, do exist, and they can cause significant pain, particularly if the herniation irritates a nearby nerve. The classic symptom is pain that radiates down the leg (sciatica), often with numbness or pins and needles.

They're not impossible in sailors. But they're also not the most common cause of the back pain that competitive sailors experience, not by a long shot.

What Is Actually Causing Back Pain in Most Competitive Sailors?

The most common cause of lower back pain in dinghy and skiff sailors is something far less dramatic, and far more fixable: load tolerance failure. The structures of the lower back muscles, joints, ligaments, and discs, are being asked to do more than they're currently conditioned to handle.

Hiking in an ILCA or a 470 places the lower back under sustained compressive and rotational load for hours at a time. The lumbar spine is simultaneously supporting significant force from the hiking position, absorbing movement from the waves, and rotating as you respond to the boat. Done across multiple consecutive race days, in conditions where fatigue is setting in and technique degrades, this is a genuinely significant physical demand.

When the surrounding muscles, the deep spinal stabilisers, the hip flexors, the abdominals, aren't conditioned to sustain that load, the passive structures of the spine (joints, ligaments, discs) pick up the slack. And eventually, they tell you about it.

That's not a slipped disc, think of it more like a load tolerance problem. And it responds very well to the right rehabilitation, once someone actually identifies what's driving it.

Why Does the Slipped Disc Myth Matter?

It matters because what you believe about your injury shapes what you do about it.

If you believe you've done irreversible structural damage (that a disc has moved out of place and is pressing on a nerve) you're likely to rest more, move less carefully, and approach your sailing with an underlying anxiety about re-injury that affects your performance and your confidence.

If you understand that what's actually happened is a load tolerance issue, that the structures of your back were asked to do more than they were conditioned for, and that the right progressive loading will rebuild that capacity, you approach rehabilitation very differently. With more confidence. More consistency. And much better outcomes.

The language we use about injuries is not neutral. It affects how sailors think about their bodies, how willing they are to return to training, and how well they actually recover.

What About Shoulder Pain, Hip Pain, and the Other Things Sailors Don't Talk About?

Lower back pain gets the most attention in the sailing community, but it's far from the only overuse injury pattern that competitive sailors experience.

Skiff and trapeze sailors frequently develop shoulder problems, rotator cuff issues, AC joint irritation, bicep tendinopathies, from the sustained grip and overhead demands of trapezing and sail handling. Keelboat grinders carry enormous cumulative upper-body load across multi-day regattas. Dinghy sailors in extreme hiking positions develop hip flexor and knee overuse injuries that build quietly across a season before becoming impossible to ignore.

Almost all of these are overuse injuries. They develop gradually, often without a clear moment of injury. And because of that, sailors often dismiss them - 'it's just part of the sport' - or misattribute them to something more dramatic than the gradual accumulation of load over weeks and months.

They're also almost all very responsive to the right rehabilitation. The key phrase being 'the right rehabilitation' which means rehabilitation that understands the demands of your specific sailing class, addresses the actual driver of the injury, and progressively rebuilds your capacity to handle the loads of competitive sailing.

What Should You Actually Do If Your Back (or Anything Else) Is Giving You Trouble?

First: get it properly assessed. Not googled. Not self-diagnosed based on what a teammate said at the sailing club. Assessed by someone who can actually identify what's happening and why.

Second: understand that pain is not damage. A sore back after a big training weekend is not necessarily a sign that something has gone wrong structurally. It may simply be feedback that the load exceeded your current capacity and that's useful information, not a crisis.

Third: don't just rest and hope. Overuse injuries in sailing don't resolve with rest alone, they resolve with progressive, structured loading that gradually rebuilds the capacity that was exceeded. Rest reduces the pain. Rehabilitation fixes the problem.

If you're a competitive sailor dealing with back pain, shoulder pain, hip pain, or anything else that's affecting your time on the water, get a proper assessment with someone who understands sailing.

Frequently Asked Questions

Is back pain normal for competitive sailors?

Lower back pain is common among competitive sailors, particularly dinghy and skiff sailors who hike extensively, but it isn't inevitable. It typically reflects a mismatch between the load being placed on the back during sailing and the current capacity of the supporting muscles and structures. The right strength and conditioning programme, combined with good technique, can significantly reduce risk.

Can I see a physio for a sailing injury without a GP referral in Dublin?

Yes. You can book directly with Aisling Keller at RAPID Physio, Dublin 12, without a GP referral. Your initial assessment will include a full sailing-specific evaluation and a personalised rehabilitation plan.

Do I need to stop sailing while I'm in rehabilitation?

In most cases, no - not completely. The goal of good rehabilitation is to manage load intelligently rather than eliminating it entirely. Aisling will advise on what's safe to continue and what needs to be modified, based on your specific injury and your sailing programme.

Does RAPID work with all sailing classes?

Yes. Aisling has personal experience across dinghy, skiff, and keelboat sailing, including racing ILCA (Laser) class at elite level and builds rehabilitation programmes specifically around the physical demands of each class.
