The gym is a converted cabin on the lower deck: two metres of headroom, a treadmill, a cable stack, and a rack of dumbbells up to 32 kg. You are on passage in a beam swell, and a guest wants to train. Every one of those dumbbells is a loose object, and so is the guest.
The yacht gym and its limits
| Constraint | What it means in practice |
|---|---|
| Space | Often 10-20 m2. No room for a lunge lane, a barbell, or a swung kettlebell |
| Headroom | Frequently under 2.1 m. Overhead press, jumping and inversions may be impossible for a tall guest |
| Motion | The floor moves. Balance work and heavy loading become genuinely hazardous |
| Fixed equipment | Machines are bolted down for a reason. Never unbolt or reposition them |
| Ventilation | Enclosed gyms get hot and humid fast. Check the air handling before a session |
| Flooring | Rubber matting; check it is bonded down and not lifting at the edges |
Free weights in a seaway
This is the single most important safety point in the module. A dumbbell is a projectile the moment the boat rolls. In any meaningful sea state:
- Stow all free weights in their racks or lockers, secured, before you leave the gym.
- Do not programme heavy free-weight work underway. A guest who loses balance under a loaded bar or overhead dumbbell can be seriously injured.
- Substitute: machines, cables, bands, bodyweight, floor-based work — anything where the load cannot fall on a person.
- Lying-down pressing movements are especially unforgiving. Avoid them underway.
- If the boat starts to move mid-session, end the session. "We will pick this up at anchor" is the right call and no guest has ever been harmed by it.
Training on deck
Deck sessions are what guests remember, and they carry their own risks.
- Heat and humidity. Do not train guests in the middle of a Mediterranean or Caribbean afternoon. Aim early morning or evening.
- Sun. Shade, hats, sunscreen, and short sessions. Sunburn on a sundeck is a guest complaint.
- Surface. Teak is slippery when wet or when a mat slides. Check the surface, dry it, use non-slip mats, and choose a level area.
- The edge and the water. Never place a guest so that a lost balance takes them towards the rail, a hatch, a low guardrail or an open transom. Set up facing inboard, well clear of the perimeter.
- Obstacles. Cleats, tracks, tender lifting points, sunbeds. Clear the space and walk it yourself first.
- Noise and privacy. Guests may not want an audience; crew may need the deck for work. Coordinate with the bosun.
Choosing the right space
Ask three questions before you commit to a location: Is it stable? Is it cool enough? Is a fall survivable and undramatic? If any answer is no, move the session.
Onboard Notes
- Walk the space before every session, not just the first one. Deck layouts change with tender ops and sunpads.
- Agree with the bridge before any on-deck session underway. The officer of the watch may know about a course change you do not.
- If in doubt about sea state, train inside on stable equipment, or do mobility and breathwork on the mat instead.
- Preparatory study only. Nothing here qualifies you to instruct. Leading guests requires an accredited qualification and professional indemnity insurance.
