The French boating market in 2026: decline or transformation? 🇫🇷⛵

New boat sales in France are down 5.2% year-on-year — but the figures tell only part of the story. While new boat purchases remain under pressure, the used-boat market, maintenance, refit and charter activities are proving more resilient.

The real shift? Customers are taking longer to decide, buying more cautiously and increasingly focusing on the use and value of their boats rather than ownership itself.

A closer look at the French market reveals why the boating industry may be undergoing a transformation rather than simply a downturn.

WASTEWATER DISCHARGE REGULATIONS FOR YACHTS WORLDWIDE

Anyone planning a long-distance voyage or moving between cruising areas should familiarize themselves with the wastewater discharge regulations that apply to toilets and blackwater around the world. They can vary considerably from one region to another — almost like a book with seven seals.

And that is exactly what makes the topic so interesting. So I had this map created to give a general overview.

🔴 RED: Discharge prohibited — for example, in many harbors, bays, protected areas, and designated coastal waters.

🟡 YELLOW: Discharge permitted only under certain conditions — depending, for example, on distance from the coast, wastewater treatment, or vessel type.

🟢 GREEN: In certain offshore areas, discharge may generally be permitted, provided the applicable requirements are met.

Particularly strict regulations apply in areas such as the Baltic Sea, numerous U.S. No-Discharge Zones, and various protected areas around the world. In other regions, distance limits such as 3 or 12 nautical miles may apply — but these rules do not automatically apply in the same way to every private yacht.

The key point is: there is no single worldwide set of “yacht wastewater laws.”

My recommendation: When in doubt, keep it in the tank and pump it out ashore.

Because being “far offshore” does not automatically mean that discharge is legally permitted.

By the way: even with an approved wastewater treatment system on board, discharge in U.S. coastal waters can still be prohibited in certain areas and violations can be subject to severe penalties.

In other areas, having a properly approved marine wastewater treatment system on board can, of course, be a very sensible choice.

We build wastewater treatment and holding-tank systems in many different sizes — including systems for yachts with up to 12 people on board.

Any technology can fail from time to time. It is particularly frustrating when a problem occurs just before the weekend or when, like many others, you are making the most of the final days of the season and are already on your way to winter storage with your yacht.

However, many technical problems have a very simple underlying cause that we can often identify during a short video call. In some cases, you may even be able to fix the problem yourself afterwards.

For such enquiries, you are welcome to contact our hotline and briefly describe the problem. If you would like us to call you back directly, simply include your mobile phone number. Otherwise, we will respond by email:

LATE SUMMER IS THE BEST TIME OF YEAR ON BOARD FOR MANY ⛵️

The peak of summer is over, the cruising areas are getting quieter, and peace is returning to the anchorages. For many, this is when the most enjoyable time of the year on board begins.

And for more and more people, a yacht or houseboat is no longer just a holiday destination — it has become a home and workplace.

To make that lifestyle work comfortably and sustainably, three technical areas are crucial:

⚡ 1. Energy – not just for the batteries

Reliable 230V power with sufficient capacity is no longer a luxury on board. Laptops, coffee machines, electric cookers, kitchen appliances and bread makers all need dependable power.

With a properly sized energy system, you can even cook entirely electrically today — for example, with induction. This not only reduces gas consumption but can also provide a significant safety benefit on board.

💧 2. Water – why keep carrying bottles?

If you live on the water, access to clean drinking water should be a given.

With drinking water treatment and, depending on the cruising area, seawater desalination, you can produce both drinking and utility water directly on board.

That saves plastic, money and, above all, valuable storage space. And yes — it also means your shower can occasionally last longer than 30 seconds. 😉

♻️ 3. Wastewater – the underestimated challenge

This is where things get technical — and, in many cruising areas, infrastructure can become a real problem.

A widespread and reliably functioning network of wastewater pump-out stations simply doesn’t exist in many places. Numerous older stations are now broken or have disappeared altogether. At the same time, nobody wants to discharge wastewater illegally into the water.

Our solution: fully biological wastewater treatment directly on board.

Our enteron® marine wastewater treatment systems operate without chemicals and are designed to require as little maintenance as possible. Regular inspections and necessary service work can be carried out by the boat owner.

The treated water is purified to a level that allows discharge again. The systems are IMO-certified and are particularly interesting for larger yachts, houseboats and boats used as permanent residences.

👉 So the real question is:

How self-sufficient does a boat actually need to be for you to live on board permanently — and comfortably?

Are solar, batteries and a watermaker enough? Or has onboard wastewater treatment become just as essential to modern marine technology?

What do you think? What is absolutely essential on board if you want to live there for several months — or even permanently?

I’m looking forward to hearing about your experiences and opinions.

And if you’re still planning your life on board, I’m always happy to help personally:

WHEN SUMMER BECOMES THE ULTIMATE STRESS TEST FOR YACHT SYSTEMS

A familiar sight in Mediterranean marinas these days: crowds of tourists gather around modern yachts, watching thick streams of water continuously discharge from outlets along the hull.

Theories quickly follow: water ingress, engine cooling water, even shower wastewater…

The reality is much simpler.

Mediterranean hotspots are packed during the summer, and almost every modern yacht is running its air conditioning—often together with a watermaker—whether at anchor or in the marina.

The reason is obvious: yachts heat up incredibly fast under the blazing sun. Just like a parked car, interior temperatures of 60°C (140°F) or more are not uncommon. Modern yachts with large glass surfaces, teak or synthetic teak decks absorb even more heat, making efficient ventilation and air conditioning an essential comfort feature rather than a luxury.

One question we hear regularly is:

How large do the seawater intakes actually need to be?

An 18,000 BTU marine air conditioning unit requires approximately 5,000 litres (1,320 US gallons) of seawater per hour at full capacity to cool its condenser. Add a watermaker, and the demand increases even further. A system producing 100 litres (26 US gallons) of fresh water per hour typically requires around 1,000 litres (264 US gallons) of seawater per hour, with approximately 900 litres being discharged back into the sea—slightly warmer and with a higher salt concentration.

In the Mediterranean, where seawater temperatures often exceed 27°C (81°F) during summer, seacocks and through-hull fittings operate under particularly demanding conditions.

For this reason, we believe non-metallic composite seacocks are the best solution. We consistently install TruDesign products because they do not corrode and won’t leave rust stains around hull outlets. Through-hulls and discharge fittings should ideally not be made of metal. Even stainless steel can suffer from crevice corrosion under unfavourable conditions.

Here’s another interesting fact:

A 1-inch seacock installed at approximately 1 metre (3.3 ft) below the waterline can theoretically supply up to 8,000 litres (2,110 US gallons) of seawater per hour. Whether multiple consumers—such as several air conditioning units and a watermaker—can safely share the same intake, and how an intelligent flow controller can optimise the entire system, is something we’re always happy to discuss.

We exclusively supply and install -Airco air conditioning systems and Schenker Watermakers professionally installed on your yacht.

So next summer, you can stay cool on board while everyone enjoys a proper shower:

Many owners of houseboats and permanently inhabited vessels face the same challenge: what to do with 🚽 wastewater on board?

The reality is simple: life on board generates wastewater volumes similar to those of a household on land.

While holding tanks are mandatory, they often create problems ➡️ unpleasant odours, insufficient capacity, and limited disposal options.

The result: environmental impacts that are neither acceptable nor compliant with today’s regulations.

This is exactly why we developed the enteron® range.

Our fully biological wastewater treatment systems provide a sustainable and convenient solution for ships and houseboats – completely chemical-free and fully automated.

✔ Fully biological wastewater treatment
✔ No chemicals required
✔ Fully automatic operation with display monitoring
✔ Optional remote monitoring – ideal for charter fleets
✔ Retrofit-friendly – in many cases installed within a single day
✔ IMO-compliant and certified accordingly

The enteron® 50 single is designed for vessels equipped with an existing holding tank.

The enteron® 50 offers an integrated solution for up to four people. For larger applications – including greywater treatment as well as wastewater from washing machines and dishwashers – the enteron® 80 to enteron® 160 models are available.

Whether you live aboard long-term, operate a houseboat, or want to future-proof your charter fleet, we would be pleased to help you identify the right solution for your needs.

WE OFFER WATERMAKER SERVICE AND INSTALLATION

Of course, we can service, preserve, inspect, and, if necessary, repair watermakers of all brands.

Ultimately, most systems are based on similar principles. In fact, many larger ⛵️🛥️yachts are equipped with watermakers from different manufacturers, and we are fully capable of working on those systems as well.

For new installations and deliveries, however, we exclusively supply Schenker Watermakers.

Whether you have questions about your existing watermaker, need assistance with troubleshooting, require spare parts or preservation services, or would like to discuss whether a watermaker is the right solution for your yacht, we would be pleased to hear from you. Feel free to contact us for expert advice and support:

30/04/2026

More and more skippers are looking for centralized control of all their yacht systems via a single display ➡️ right from the helm in the cockpit. Fewer switches, better overview, and maximum control: that’s the clear trend, especially on large motor yachts.

A recent real-world example: the installation of a cube 65 Schenker Watermakers integrated with a multifunction display. The owner can operate the system either via a dedicated control panel or directly through the existing chartplotter.

Technically, the system stands out with its brushless motor (virtually silent in operation) combined with high efficiency — delivering around 65 l/h with only about 300 watts of power consumption. Thanks to soft start and intelligent speed control, the watermaker automatically adapts to varying water conditions. In this combination, the system sets new standards.

Installation is equally practical: the system is ready for operation within a single day. Even routing freshwater lines across the vessel (often the most time-consuming part) can be handled efficiently using our proven methods.

Particularly noteworthy is the range of control options:

• classic switch with programmable flushing function for periods of absence
• compact mini touch display
• large touchscreen with advanced service and visualization features
• full integration into the onboard network for control via existing displays

Network integration follows a plug-and-play approach: connect, auto-detect, and operate immediately.

The result: maximum comfort, minimal noise, and seamless integration into modern onboard systems — exactly what owners and shipyards expect today.
