Check out this big ass sailboat ⛵

Meet Pyxis Ocean, the world's first cargo ship that just set out for its maiden voyage from China to Brazil:

The Pyxis Ocean's maiden journey, from China to Brazil, will provide the first real-world test of the WindWings - and an opportunity to assess whether a return to the traditional way of propelling ships could be the way forward for moving cargo at sea. source

Each one of those fascinating "windwings" is 37.5 m (123 ft) tall and is made from the same materials as wind turbines to make them more durable. According to the company, they can be retrofitted to older vessels as well and their goal is to reduce emissions by up to 30%. Possibly more if combined with other green options.

Windwings are developed by the UK firm BAR Technologies, which hopes that by 2025 half of new cargo ships will be using them

"I do predict by 2025 half the new-build ships will be ordered with wind propulsion. The reason I'm so confident is our savings - one-and-a-half tonnes of fuel per day. Get four wings on a vessel, that's six tonnes of fuel saved, that's 20 tonnes of CO2 saved - per day. The numbers are massive." said John Cooper, head of the company

Yeah, honestly I doubt we will see this numbersb materialize... Still those are some bad ass sails. Hopefully we will see more of them in the future

Here's a video showing them in action

I really wonder how these will behave in a storm...I guess we will know soon enough :)
