Your energy
A system tailored to you
Your peace of mind
Installation and support
Your own power. Your own course.
Your anchorage.
Your own energy.
You want to stay longer in a beautiful anchorage, without heading back to a marina just to recharge your batteries. VA Maritime Design helps you find an energy system that suits your life on board.
From the first conversation through installation and support, you have one point of contact for your complete energy system.

What is off-grid sailing?
More time on the water.
Less reliance on shore power.
Off-grid means using your own energy on board for a period without connecting to shore power. How long that lasts depends on your consumption, battery storage and how you recharge along the way.
Stay where you want to be
A quiet bay or a sheltered anchorage. Your plans are the starting point for the system.
Power what you need
Fridge, lighting, navigation or your laptop: together we map out what you want to use on board.
A system that fits
Battery storage, charging options and your onboard use are designed to work together.
Your desired days off-grid are our starting point. Together, we explore what is possible for your yacht.
What VA can do for you
From an idea to
power on board.
A complete solution, built around your needs and explained clearly at every step.

Support & troubleshooting
After installation, you can get in touch with questions or faults. A familiar point of contact for your onboard system.

Questions about energy on board
What would you like to do without shore power?
How many days can I stay off-grid?
That depends on your daily consumption, the usable energy in your batteries and the charging options. We start with your desired number of days and assess what suits your yacht.
What does a complete system with installation cost?
The components, your existing installation and the work on board determine the price. After discussing your needs, you receive a proposal tailored to your yacht.
Where does VA install systems?
VA Maritime Design works from Zwolle in the Netherlands. The service area is not limited to a fixed region. We discuss installation at your yacht’s location and the practical schedule together.

Get in touch
Where would you
like to drop anchor?
Tell me about your yacht and your plans. How many days would you like to stay without shore power? And what equipment would you want to use?
Looking for a complete energy system for your sailing yacht, including installation? I would be happy to discuss a solution tailored to your needs. I work from Zwolle. Let me know where your yacht is located so we can discuss installation on site.
An enquiry starts a conversation. It does not commit you to an order.
