Introduction Sailing enthusiasts, imagine powering your vessel with the very essence of your environment – the sea itself. Water generators, like the groundbreaking Watt&Sea system, do just that. In this post, we delve deep into the world of water generators, uncovering their efficiency, minimal maintenance requirements, and unobtrusive operation. Let's set sail into a greener future! Efficiency on the Move One of the most remarkable features of water generators is their ability to generate electricity as your vessel sails. These innovative systems harness the energy produced by the movement of water against their adjustable blades. This unique characteristic makes them highly efficient, especially during passages and while cruising. As you navigate the waves, Watt&Sea quietly transforms water's kinetic energy into a renewable power source. Quiet and Unobtrusive Much like wind generators, water generators operate with a hushed grace that doesn't disturb the tranquility of your sailing experience. Imagine gliding across the water, listening to the soothing sounds of the sea, without the disruptive hum of traditional generators. Watt&Sea's commitment to preserving the serenity of your voyage is truly remarkable. Minimal Maintenance For sailors, the journey is everything. Water generators enhance this experience by requiring minimal maintenance. This means you can focus on your adventure, not on energy management. However, it's important to look after your propellers and carry spare units, especially if you plan on crossing seaweed-heavy waters, as we did during our Atlantic journey towards the Caribbean. Watt&Sea stands out as a trusted hydrogen supplier, offering both 300 Watt and 600 Watt systems with varying shaft lengths. These systems are designed to be fixed at the transom of your boat, weighing between 8 to 9 kilograms depending on the shaft length. They are compatible with 12 and 24 Volt systems. Remember to disconnect the hydrogenerator when your [...]

When it comes to the freedom and flexibility of sailing, there's nothing quite like it. The ability to drop anchor and stay away from the harbor for extended periods is a true luxury. However, achieving this level of independence from essentials like diesel, water, and electricity is a sailor's challenge. While sailors who frequent different ports may not be bothered by these concerns, for those embarking on long-distance bluewater sailing, self-sufficiency becomes paramount. In this article we share our experience using different systems on SY Ambra including power and fuel consumption, solar power and lithium batteries. In addition we cover alternative systems, please click below for more information: -Wind generators -Hydrogenerators -Fuel cells and biofuels -Electric propulsion systems Power Consumptions and Demand Today sailors install and enjoy all kind of luxury and additional power hungry systems. We all like a cool drink, the benefits of a dish washer or washing machine, 110/220V power plugs to charge Laptops, tablets or communication devices such as Starlink. To dimension the onboard energy system correctly, it's crucial to assess the energy consumption of all appliances and devices on board. You need to make a list of all devices on board, the number of hours you are going to use them while sailing or on anchor to estimate the average power consumption. This will help you to determine your average power consumption and the size of your batteries and generators. Here is a list of appliances you should look at: Modern technology, like LED lighting, allows for significant energy savings. For instance, a 4-watt LED tricolor light at 24 volts consumes only around 0.2 amperes per hour, in stark contrast to three navigation lights, which could draw 3 amperes per hour along with the possibility of additional deck lights. Instruments, while sailing your plotter [...]

Electric hybrid and propulsion systems for sailing vessels, such as those offered by companies like Oceanvolt (website: https://oceanvolt.com/), are innovative technologies designed to revolutionize the way sailing vessels operate. These systems combine traditional sail power with cutting-edge electric propulsion technology, resulting in a more sustainable, efficient, and eco-friendly sailing experience. Here's a closer look at how these systems work and their key components: 1.Electric Propulsion System: Electric propulsion systems are the heart of the setup. They consist of electric motors and controllers that replace or complement the traditional diesel engines found in sailing vessels. These motors are powered by batteries and have several advantages, including quiet operation, reduced emissions, and instant torque for enhanced maneuverability. Today you find shaft drive systems or pod drive systems. The new 48V pod drive system, combine a sail drive unit and hydrogenerator. The pod drive can control the pitch of the propeller blades to optimize the angle for ultimate efficiency in both propulsion and electricity generation. Today a propeller on a sailing yacht is only foldable to offer less resistance while sailing. 2. Battery Bank: The power source for electric propulsion is a battery bank. These batteries store electrical energy, typically from renewable sources like the hydrogenerator, solar panels or wind turbines. The stored energy is then used to drive the electric motors, providing the vessel with the necessary power for propulsion. 3. Regeneration: One of the key features of these systems is their ability to regenerate power. When the sails are capturing wind energy efficiently, excess energy can be redirected to recharge the batteries. This regenerative feature extends the vessel's range and reduces overall energy consumption. 4. Hybrid Capabilities: Electric hybrid systems often offer a hybrid mode, allowing sailors to switch between electric and traditional propulsion as needed. This flexibility ensures reliability and [...]

The world of sailing vessels is undergoing a transformative change as the quest for cleaner and more sustainable energy sources gains momentum. Traditional fossil fuels are increasingly being replaced by innovative alternatives, and two of the most promising options on the horizon are biofuels and fuel cells. In this article, we'll embark on a journey through the world of these green energy solutions, exploring their potential to reshape the future of maritime travel. Biofuels: A Breath of Fresh Air Biofuels are a class of renewable energy sources derived from organic materials such as algae, plant-based oils, and animal fats. They have gained prominence in the quest for greener sailing vessels due to their environmentally friendly and sustainable nature. One of the primary advantages of biofuels is that they are carbon-neutral. This means that the carbon dioxide released when burning biofuels is roughly equivalent to the amount these organic materials absorbed during their growth. In essence, biofuels offer a way to significantly reduce the carbon footprint of sailing vessels. Biofuels can be used in existing diesel engines with minimal modifications, making them a practical choice for those looking to transition from traditional fossil fuels. As technology advances, we can expect biofuels to play an increasingly vital role in the maritime industry's pursuit of sustainability. Fuel Cells: Power from the Future Fuel cells are another innovative solution that's gaining traction in the world of sailing vessels. These devices generate electricity through an electrochemical process, making them an appealing source of clean and efficient energy. Fuel cells can be powered by a variety of fuels, including hydrogen, natural gas, and, in our context, biofuels. One of the most significant advantages of fuel cells is their high energy efficiency. Unlike internal combustion engines, which lose a substantial amount of energy as heat, [...]
