A guest tells you over canapes that her back has been "playing up" and asks whether you can give her some exercises for it. You know a stretch that helped you. You are three seconds from giving rehabilitation advice to a stranger with an undiagnosed spinal problem, from a yacht, with no qualification and no insurance.
Scope of practice is the fence around your job. This lesson tells you where the fence is.
What you need before you instruct
| Discipline | Recognised baseline | Notes |
|---|---|---|
| Personal training | An accredited Level 3 Personal Trainer qualification (or national equivalent) | Level 2 gym instructor covers inductions and supervision, not programming |
| Yoga | A Yoga Alliance-registered teacher training (200hr minimum) or equivalent recognised training | Practising for years is not a qualification |
| Pilates | A recognised Pilates certification — mat and/or equipment, they are separate | Equipment work requires equipment-specific training |
| All of the above | Professional indemnity and public liability insurance valid for where and how you work | Check it covers instruction on a vessel, and outside your home country |
Add a current first aid certificate, and check whether your flag state, the yacht's insurer or the management company imposes anything further. Some do.
Inside scope
- Leading sessions you are qualified to lead, for apparently healthy adults who have been screened.
- Teaching technique, cueing, structuring a session, progressing and regressing exercises.
- Gym inductions and safe equipment use.
- General, non-prescriptive comments about training.
Outside scope — always
- Diagnosing anything. You do not know what a pain is.
- Rehabilitation protocols. Treating an injury is a clinician's job.
- Programming for pregnancy, or for a diagnosed medical condition, unless you hold the specialist qualification for it. Refer to a doctor and to a specialist-qualified instructor.
- Prescribing diets, supplements, or weight-loss plans. Nutrition talk stays general; anything individual goes to a registered dietitian.
- Anything you would struggle to justify to an insurer afterwards.
The honest bit about fitness culture
A great deal of fitness marketing is unevidenced: detox programmes, rapid fat-loss claims, "toning" a specific spot, elaborate supplement stacks. Guests will bring these ideas aboard and ask you to endorse them. You do not have to argue — but you do not have to repeat them either. "That is outside what I can advise on" is a complete sentence, and it is the professional answer.
Onboard Notes
- Keep certificates and insurance documents scanned and accessible. The captain may want them on file before you lead anything.
- If the yacht is billing guests for sessions, the exposure is the boat's as well as yours. Management will want to see the paperwork.
- When a guest describes a symptom, your script is: screen, refer, stay in scope. "That is one for a doctor — I am not qualified to advise on it."
- Being under-qualified and enthusiastic is more dangerous than being under-qualified and honest.
- Preparatory study only. Nothing here qualifies you to instruct. Leading guests requires an accredited qualification and professional indemnity insurance.
