Sunreef Yachts – Eco 80 Sail Catamaran

Most Luxurious + Most innovative solar system

The Eco 80 Sail Catamaran is one of the electric solar boats provided by Sunreef Yachts.

It features a unique “solar skin” that covers all composite structures on the boat, including hull sides, boom, mast, bimini, and superstructure. This green tech makes it possible to place solar panels where it wouldn’t normally be possible (like the hull and any other smaller but useful surface) and provide enough solar energy from every angle.

The boat is 80-feet long (24.38 meters) and includes electric motors that push it smoothly over the water without causing any vibrations or noise.

Besides being solar powered boat, the Eco 80 Sail Catamaran can also be powered by wind and hydropower. It is designed with a sail on its structure, allowing it to tap into wind power and supplement the solar.

The solar powered sailboat generates enough green power not only to propel the boat and keep it moving but also to charge the essential electric water appliances and other water-sport toys.

So far, the Sunreef Yachts Eco solar sailboats have earned a good reputation for being eco-friendly and sustainable. Besides, this solar powered catamaran takes its commitment to the environment a notch higher by using recycled materials, natural fibers, and non-toxic paints to create their boats.

It is no wonder that Sunreef Yachts have been winning environmental awards for so many years. This solar sailboat is one of the most remarkable boats you can ever invest in and it clearly shows the latest advancements in technology.

And even though the Serenity 64 is smaller than the Serenity 74 model also built by Serenity, it still provided an elegant feel and a smooth sailing experience.

Solar Boats Pros and Cons

The sun is a powerful and free source of energy, making solar power an attractive option for those looking to power their yacht. Solar panels can be used to generate electricity to run the yacht’s lights, appliances, and even the engine. Solar power can also be used to heat water for showers and laundry. But, what are the pros and cons of solar catamarans?

Here’s a quick summary of the solar yachts’ advantages and disadvantages:

Advantages of solar boats ✅	Disadvantages of solar boats ❌
Eco-friendly: solar power is clean and renewable	More expensive than standard boats
They (mostly) don’t require fuel	Solar panels work well only during sunny days
Reliable	You will still need a (diesel) generator onboard: for both safety and continuity of power
Reduced maintenance costs	Reduced stability while cruising (If without sails)
Cost-effective in the long run	The smaller versions of solar yachts will have quite limited cruising speed when using only the power from solar
Potentially unlimited range, especially for the larger solar catamarans
Possibility to sell back the excess power to shore (when connected)
No restrictions on electrical use

One of the main benefits of solar power is that it is renewable and environmentally friendly. Solar panels have no emissions and do not produce pollution. In principle, they also do not require fuel, making them very cost-effective in the long run. Solar power is also very reliable, as the sun is a constant source of energy.

There are a few disadvantages to solar power. Solar panels can be expensive to install, and while they require less maintenance, this can be quite costly, especially when it will come time to replace the batteries. Solar panels also need to be pointing directly at the sun to be effective, so they may not generate power on cloudy days or at night.

But there’s more, let’s see what some sailing experts are thinking about solar catamarans!

Sailing expert’s solar Boat review

Recently, one of the most popular sailing YouTube channels, Saliling La Vagabonde, published a very honest and interesting review of the solar powered yacht Silent 55. Here’s a summary of their experience:

• 7 Days onboard (6 nights)
• Travelled 145nm with an average speed of 7 knots
• Generator used for about 12h (in total)
• Fuel consumed: 208 liters

Here are some interesting observations they made:

• While cruising it may feel less stable than a standard sailing boat because it doesn’t have a sail to stabilize it when hitting the waves.
• For the Silent 55 it was possible to move at about 3 knots by using only the power generated by the solar panels (without using the batteries) on a sunny day. This means that if you are moving the solar yacht around quite frequently, you will end up using the generator quite a lot to produce the necessary power.
• When the batteries are out of power, the Silent yacht is using a (diesel) generator to supply the necessary power to keep the boat moving and to power the appliances.
• A great luxury yacht with all the comforts and going in the right direction for the future of the sector.
• Overall, the Silent Yacht is a great eco-friendly alternative to a power boat, while if you are thinking about cruising around the world, you would be probably better off going for a standard sailboat (or for some of the hybrid alternatives mentioned in this article, like the HH44).

Why are solar yachts all catamarans?

Solar yachts are all catamarans for 2 main reasons:

• Catamarans have a larger surface, which allows for placing more solar panels and also offers more room for the batteries onboard.
• Catamarans have efficient hulls for their size. This reduces their power consumption while moving.

This makes catamarans the ideal platform to build a solar-powered boat.

Conclusion

Modern solar electric boats are undoubtedly an eco-friendly choice in sea travel and a form of green tourism. Not only do these electric boats provide a smooth sailing experience, but they also reduce the release of emissions into the atmosphere, reducing the environmental impact and enhancing sustainability.

Luckily, given their size, solar catamarans can charge themselves (unlike electric cars), so they can sail indefinitely without the need to stop for refueling.

If you are environmentally conscious and looking to get a boat that is more viable, desirable, and eco-friendly, you may consider investing in one of the solar yachts discussed in this article!
