I have crewed for people I had met once on a video call, and I have skippered for crew who answered an advert. Both work, and both can go badly. The difference almost never comes down to sailing skill. It comes down to whether the crew understood that they were a guest in someone's home that happens to float, and behaved accordingly.
So this is the brief I wish someone had handed me the first time I stepped aboard a stranger's yacht in a French marina. If you are on the other side of it and looking for hands instead, the companion piece on finding crew for a French cruise covers the recruiting end.
The boat is not democratic
A yacht has one skipper, and decisions are theirs. You can offer an opinion, once, clearly. After that you do what is asked, promptly, even if you would have done it differently. This is not about ego. At sea, a boat with two people each quietly sailing their own plan is a dangerous boat. Mid-Channel in fog, when you cannot see the bow, is not the moment to relitigate the reefing decision. The article on what to do when fog catches you mid-Channel makes the case better than I can: clarity of command saves you.
The flip side is that a good skipper explains the why when there is time, and a good crew listens. If the skipper is barking orders with no context and no patience, that is a red flag about them, not you.
Money: settle it before you slip lines
Nothing sours a trip faster than a vague money arrangement curdling into an argument in port. The convention is straightforward and you should confirm it before you sail, not after:
- Crew contribute to consumables: food, fuel, gas, and the share of marina fees for nights you are aboard.
- Crew do not pay for the boat, its insurance, or its maintenance.
- The kitty is usually pooled at the start, topped up as it runs down, and squared at the end.
Have actual cash. Plenty of small French capitaineries still prefer cards but some take cash only for short stays, and a visitor berth for a 10 to 12 metre boat runs around 30 to 60 euros a night in season. Offer to pay your share without being chased. If the skipper waves it away, insist gently once, then let it go.
The heads, the galley, and the small spaces
Two things end more friendships than any storm: the heads and the washing-up.
Learn the heads routine the moment you board, before you need it, and follow it to the letter. Many boats have specific pump-through procedures and a strict no-paper rule. Blocking a marine toilet at sea is a genuine emergency and an unforgettable one. Ask, do not guess.
In the galley, the rule is simple: if you used it, clean it. Do not leave a single mug for the skipper to deal with. On a small boat the mess is shared physically even when it is not shared morally, and the person who tidies as they go is the person who gets asked back.
Keep your kit contained. You have one bunk and one locker, probably less than you think. Soft bags only, never a hard suitcase, because there is nowhere to stow it. Your gear lives in your space, not draped over the saloon.
Watches and night sailing
If you say you can stand a watch, stand it properly. That means staying awake, keeping a real lookout, monitoring instruments, and waking the skipper the instant anything changes: a light you cannot identify, a wind shift, a noise, a doubt. Skippers are not annoyed at being woken. They are annoyed at being woken too late.
Do not be a hero about tiredness. If you are falling asleep on watch, say so and hand over. A French Channel crossing through busy shipping demands genuine alertness, and the Dover Strait traffic separation scheme is no place for a microsleep.
Hand over cleanly. The off-going watch briefs the on-coming one: course, traffic, what the skipper said, anything pending. Thirty seconds of handover prevents an hour of confusion.
The social layer, ashore
French cruising has a rhythm that the marina brochures never quite capture. You make your landfall, you tidy the boat, and then the evening opens up: a wander into town, a meal at a harbour restaurant, a beer in the cockpit while the boat next door does the same and conversation drifts across the pontoon. This is half the point of the trip.
As crew, your job ashore is to be good company and to read the room. Some skippers want the long dinner and the late chat with the neighbouring crews; some want an early night and quiet. Follow their lead. A little French goes a long way at the pontoon and in the bar, and you do not need much; picking up a few phrases by the time you reach port is part of the fun rather than a chore. The friendliness of French clubs to visiting boats is real, and a polite, curious crew member makes the whole boat more welcome.
Offer to help with the boat jobs nobody enjoys: filling water, walking the rubbish to the bins, scrubbing the waterline. The crew who only appear for the sailing and vanish for the chores get a name for it.
Paperwork and borders
If you are joining a boat crossing into France from the UK, you are now a third-country national in EU eyes, and your time counts against the Schengen 90/180 allowance. Carry your passport, know your day count, and make sure the skipper has you on the crew list. Do not put your skipper in the position of explaining a missing name to the Gendarmerie Maritime. If you are bringing your own RYA ticket and wondering whether it counts for anything in France, the breakdown in RYA and French sailing qualifications side by side and the detail in ICC vs RYA certificates and what France recognises will tell you where you stand. Short version: as ordinary crew on someone else's foreign-flagged boat, you generally need no certificate at all, but it never hurts to have it aboard.
Reading the skipper and the boat
Every boat has its own culture, and the skilled crew member tunes into it fast rather than imposing their own. Some skippers run a tight, formal ship with set watch systems and a clear chain of command; others are loose and collaborative. Neither is wrong. Your job is to read which one you are on within the first few hours and match it.
Watch how the skipper handles their own boat before you offer to do anything clever. The owner who has had the same yacht for fifteen years has a way of doing every manoeuvre, and they do not want you reinventing their mooring technique. Ask "how do you like to do this?" rather than announcing how you do it. The same humility that makes a good guest in someone's home makes a good crew member on their boat.
Be honest about what you do not know. Pretending to understand a system you have never used is how things break. "I have not sailed a boat with a furling main, can you show me?" costs you nothing and saves the skipper a lot. The crew who admit gaps are trusted with more, not less, because the skipper knows exactly what they are working with.
And gauge the mood. After a hard passage, a tired skipper may want quiet, not your detailed analysis of the trip. Bring energy when energy is wanted and stillness when it is not. That emotional read is as much a part of crewing well as anything you do with a winch.
The test that matters
There is a single question that tells you whether you crewed well: would they have you back? Everything above rolls into it. Be useful, be honest about your limits, keep the boat clean, settle the money without fuss, and be decent company in port.
I have a short list of crew I will sail with anywhere, and not one of them earned that place by being the best sailor aboard. They earned it by being the person who made a small boat in a long week feel easy. Aim for that, and the rest takes care of itself.
