‼️AUTARKY NOW‼️
People who consider living on a yacht or houseboat often have a very clear vision right away: they want to be self-sufficient.
This is almost always the very first topic we discuss with interested clients. The desire for maximum independence is at the top of the list—and understandably so.
On land, especially in a highly industrialized country like Germany, we are heavily dependent on external systems: energy providers, water and sewage infrastructure, as well as gas and heating oil suppliers. While moving onto the water does not eliminate these dependencies entirely, it allows them to be significantly reduced.
⚡ Energy: The First Step Toward Autarky
On board, generating your own energy has become standard practice:
• Photovoltaics are the primary source
• Wind generators provide additional power—especially offshore
• Hydrogenerators harness energy while moving through the water (ideal for sailing yachts)
Large catamarans and houseboats, in particular, offer extensive surface areas for solar installations, enabling a high degree of energy independence. Of course, there are limitations—especially during the winter months in northern regions—but a substantial level of autonomy is entirely achievable.
💧 Water: Self-Sufficiency from the Sea
Autarky is also possible when it comes to drinking water. Water is abundant—you simply need to treat it properly.
We rely on solutions from Schenker Watermakers:
• Systems starting at 30 liters per hour for small crews
• Models like the Cube 65 or Zen 100 for larger yachts
• 150–300 liters per hour for large catamarans
Modern yachts with freshwater-flush toilets increase demand, but with the right watermaker, this is easily manageable. Powered by solar energy, it becomes another major step toward full independence.
❄️ Cooling & Heating: The Underrated Topic
Initially, many clients ask about heating solutions.
However, the far more significant issue—especially for long-term cruisers and houseboat owners—is increasingly cooling.
Larger window surfaces on modern yachts, combined with rising summer temperatures, mean that climate control will play a central role in the future.
Our solution:
Ultra-compact air conditioning systems powered entirely by direct current (DC).
This means:
• No generator required
• No inverter required
• Quiet and highly efficient operation
This allows you to cool your vessel—or at least sleeping areas—precisely when needed ➡️ ensuring restful sleep even in high temperatures.
⚙️ Propulsion: Between Electric and Hybrid
Fully electric propulsion is possible, but currently practical mainly for short distances or with very large photovoltaic areas.
That’s why many opt for hybrid solutions:
• Electric drive for harbor maneuvers and short distances
• Combustion engine for longer journeys and rapid recharging
We rely on hybrid systems from Integrel Solutions.
♻️ Wastewater: The Final Step Toward Autarky
For maximum independence, we also offer a fully biological onboard wastewater treatment system:
• Treatment of blackwater and greywater
• Fully automated operation
• Use just like at home—without limitations
Maintenance is minimal:
Add one tablet per month, perform a weekly check (about 2 minutes), and carry out annual maintenance (which you can do yourself).
👉 Conclusion
Autarky on board is not a myth—but it’s also not an “all-or-nothing” concept.
It’s a spectrum, and with the right systems, you can become more independent step by step.
