Wind generators for sailboats are a great way to power your boat while at sea. But what are the best wind generators for sailboats?

The best wind generators are designed specifically to meet the demands of sailors. These include features like high strength, small size, lightweight, and corrosion resistance. Silentwind, MarineKinetix, Superwind, Rutland, and Automaxx build the best wind generators for sailboats.

The wind can be a sailor's best friend or worst enemy. When the wind is blowing, sailors love it because they can harness its power and use it to steer their boat. But when the wind suddenly dies down, the boat will lose momentum and may even drift off course without any way of correcting for this loss in speed. This is where a good-quality wind generator comes into play!

Our experts took the liberty of testing and reviewing the best wind generators for sailboats. After hours of testing, we were able to compile a list of the best wind generators for sailboats that are available on the market today.

2. Silentwind 400 Plus

The Silentwind 400 plus is a wind turbine that has been designed for use in both marine and land-based applications. It is a reliable and efficient turbine that can provide power for boats, RVs, cabins, and other applications where a reliable source of energy is needed.

Compared to its predecessors, the new Silentwind 400 plus is equipped with high-duty carbon laminated blades. The company has dubbed these 'Silent Power Blades.' Silent wind claims that these blades provide improved wind monitoring and faster startup times than last generation's 400. These have been tested to work at turbulent speeds, and the generator is IP54 classified as waterproof/weatherproof, which means it will handle high humidity and moderate rain without damage.

According to reviews, the 400 plus has a starting speed of 4.2 knots and a max output of 425W at a 30% lower speed than other comparable generators. This is mainly due to the Silent Power Blades, which create less resistance to the wind, along with a three-phase triple alloy magnet generator

Because this turbine uses neodymium magnets, it can be used in any weather condition, unlike generators whose magnets will become demagnetized from the effects of wetness. The 400 Plus also has a 1-year warranty.

The turbine's blades are easy to access for cleaning or replacement without needing to remove the entire generator. This is an extremely valuable feature as it allows units to remain ready for operation at all times, even if they need servicing. The company claims that this generator also operates more quietly than other models on the market due to its specially designed 'silent power' blades. In addition, this model does not require oiling like some competitor products, which reduces both short-term maintenance needs and long-term expenses.

In terms of functionality, this generator can provide energy in most weather conditions due to its high-performance blades, advanced alloy magnets, and high-efficiency circuitry. It also features an easy-access design that allows for quick maintenance, which is invaluable when power needs are critical.

The Silentwind 400 plus is rated for 420, 450, and 500 watts. Its available in 12, 24, and 48V models. The 12V model is the most popular, with a weight of only 25 pounds. The turbine has an adjustable speed range of 550 to 1700 rpm, which means it can start at very low wind speeds.

Furthermore, the Silentwind 400 plus also has a built-in regulator that protects against overcharging and discharging. It is also equipped with an LED display that shows the turbine's speed, voltage, and amps being generated. This allows the user to make necessary adjustments to ensure maximum efficiency.

The only drawback we could find was that the company does not currently have a distributor in the United States. However, Silentwind has stated that they are working on this and hope to have a U.S. distributor soon. Also, due to range limitations, the Bluetooth feature is virtually useless in the open ocean.

Overall, the Silentwind 400 plus is an efficient and well-made wind turbine that can provide power for various applications. It is reliable, easy to use, and has been tested at hurricane speeds. It is a great choice for anyone looking for a dependable source of energy for their sailboats.

4. Superwind 350

The Superwind 350 is a small, lightweight wind turbine that is perfect for sailboats. When in operation, it can charge various batteries, including the 12V battery found in most sailboats. This unit has a power output of 350 watts and is equipped with an LED display that shows how much energy is being generated.

The Superwind 350 also comes equipped with Auto-Feathering Overspeed-Avoidance System. In layman terms, this system prevents the turbine from spinning too fast and damaging the blades. It does this by sensing when the wind speed is too high and then automatically slowing down the turbine. This system is especially valuable for sailors who often find themselves in high winds and can prevent costly damage to the turbine.

The blades' speed decreases as the wind speed rise to 25 knots; they start "feathering" (dumping air) to be less efficient and slower. However, as the wind dies down, the blades re-pitch, becoming more effective. In comparison to other comparable products, this action delivers a steady stream of charging current to the batteries without shutting down to avoid overcharging.

The Superwind 350 can also run in combination with solar panels and traditional diesel generators, making it the perfect choice for sailors who charge their batteries with multiple sources throughout the day. In addition, this turbine can be used in conjunction with a voltage-sensitive relay to automatically start and stop a generator based on the battery's state of charge.

Furthermore, The Superwind generator family also employs a brushless A/C stator to minimize noise and radio interference while the unit is generating power. This is a great feature for sailors who want to run power-intensive electronics such as refrigerators and air conditioners.

The only drawback we could find was that it's not the quietest. This could potentially cause issues, especially if you're trying to sleep below deck.

Overall, the Superwind 350 is a great choice for sailboats looking for an efficient and reliable wind turbine. It is easy to use and comes equipped with various safety features. It is also compatible with a variety of battery types and solar panels.

Tech Specs
