The first sail of the season is the one that catches people out. Six months of jobs, a winter of good intentions, and then a sunny April morning when the temptation is to slip the lines and go. That is exactly how an old neighbour of mine ended up drifting onto the rocks off the Var coast in his first hour out: a perished impeller he had meant to replace, an engine that overheated and died, and no time to think.
Recommissioning is not glamorous and it is not quick if you do it properly. Treat it as a sequence, not a scramble, and the first sail is a pleasure rather than a near-miss. Here is the order I work through after a winter ashore or afloat in France, refined over more springs than I care to count.
Start below the waterline, before launch
If the boat has been hauled out, the jobs you cannot do once she is back in the water come first.
- Seacocks: open and close every one. Anything stiff gets stripped, cleaned and greased now, not when water is coming through it. Check the hose clips, both of them on each fitting.
- Anodes: a zinc or aluminium anode that is more than half wasted will not see you through the season. Replace it while the keel is accessible.
- Antifouling and the prop: a fresh coat if you skipped it in autumn, and a clean, lightly greased propeller. Spring application is easier anyway, since the paint needs a dry surface above roughly 5 to 10C to cure, which a French April usually gives you and a December rarely does.
- The log impeller, the cutlass bearing, the rudder bearing: a wiggle and a look. Play that was fine last year may not be fine now.
If your boat is only now coming out of winter storage and you have not yet sorted the lift logistics for next time, our note on when to haul out in France explains why booking the slot early saves the spring panic too.
The engine: the part most likely to ruin the day
More first-sail disasters trace back to the engine than to anything else, and almost all of them are preventable in an afternoon.
- Impeller: replace it if it is over a couple of seasons old or if it sat dry all winter. Rubber takes a set and cracks. This is the single cheapest insurance on the list.
- Coolant and antifreeze: if you winterised with non-toxic propylene glycol through the raw-water system, flush it out and refill before you run the engine hard. Check the freshwater coolant level and the strength.
- Oil and filter: if you changed the oil before lay-up, good. If not, do it now, because acids left in the crankcase over winter pit bearings.
- Fuel: you left the tank around 95 percent full to keep condensation out, so check for water in the filter bowl and replace the fuel filter. Bleed the system if needed.
- Belts and hoses: a perished belt or a soft hose is a five-minute fix on the dock and a horrible one at sea.
Run the engine at the berth first, watch the temperature, watch for cooling water at the exhaust within seconds of starting, and listen. Only when it has run clean for twenty minutes does it earn the right to take you out.
Rig, sails and deck
Standing rigging gets a slow walk-round: every swage, every split pin, every clevis pin, looking for cracks, rust weeping or a strand starting to go. Tap the bottlescrews and check the lock nuts and tape. If the rig is over the age where insurers start asking questions, this is the spring to get a proper inspection rather than a hopeful glance.
Run the halyards, check the sheaves spin, bend on the sails and look for chafe and stitching that has gone over winter. UV destroys thread faster than fabric, so the seams fail before the cloth does. Reeve the reefing lines and actually pull a reef in at the dock, because the first time you need it should not be the first time you find it is jammed.
Gas, water and the systems you forget
Gas is the one that hurts people. After a winter of the locker shut, check the regulator, check the date on the hose, sniff for leaks at every joint with soapy water, and confirm the carbon monoxide alarm still beeps when you test it. Then run the cooker.
Flush the freshwater system, sanitise the tank if it sat full and stale, and run the taps until they clear. Check the bilge pump, both manual and electric, by actually putting water in and watching it move. A bilge pump that does not work is only discovered when it matters.
Safety gear: the legal and the sensible
France enforces its own safety equipment rules through Division 240, and the categories required depend on how far offshore you go. Spring is when you check dates and gaps. Flares and pyrotechnics have expiry dates and must be in life. Lifejackets need their gas cylinders and auto-inflation heads checked, the harness lines inspected, and the liferaft service confirmed in date if you carry one. We go through the visiting-boat requirements in detail in our guide to Division 240 safety equipment for visiting boats, and the start of the season is the moment to close any gaps before you are caught short.
Electrics, electronics and the paperwork
A winter ashore or afloat is hard on the electrical side, and a flat or sulphated battery is the most common reason a recommissioned boat will not start despite a perfect engine. Check every battery under load, not just the resting voltage, which lies. If you left them on a smart charger, confirm it actually held them; if you took them home, refit and test before you rely on them. Clean and grease the terminals, because winter corrosion creeps into every connection.
Power up the electronics and let them find themselves. A chartplotter that sat cold all winter often needs a long sky view to reacquire GPS, the depth and log may need recalibrating, and the VHF deserves a proper radio check rather than an assumption. If you carry AIS or a DSC radio, confirm the MMSI is still programmed and the distress button is guarded. The first time you reach for a piece of electronics in anger should not be the moment you discover it died over winter.
Then the dull but necessary paperwork. If you are a visiting boater, this is the moment to confirm your insurance certificate is in date and covers the cruising area you intend, that the ship's registration and radio licence are current, and that your safety gear certificates line up with the season ahead. Catching an expired document on the dock in April is a five-minute fix; catching it during a boarding check is not.
The dry run, then the short sail
The discipline that has saved me most: do not make the first sail an ambitious one. Run the engine at the berth. Motor a short loop in clear water with no agenda, watching gauges and listening, ready to turn straight back. Then, on a separate calmer day, do a proper short sail with the sails up and the reefing tested.
If you wintered in the south and your first proper passages will be coastal hops along the Riviera or out to the islands, ease into the early-season weather too. The seas are settled but the water is still cool and the wind can surprise you, so picking gentle conditions for the shakedown matters. Our overview of winter liveaboard life in south France covers what the shoulder months actually feel like on the water, which is useful context for judging that first window.
A worked spring, done in order, turns the first sail from a gamble into the best day of the year. The impeller, the seacocks, the gas and the flares are not exciting. They are the four things that, neglected, turn a sunny April afternoon into the story your pontoon neighbours tell for years. Do them first, sail second.
