In summary, wing sails on modern ships are innovative aerodynamic structures that enhance sailing efficiency and performance. Unlike traditional sails, wing sails operate like airfoils, generating lift and reducing drag, which can lead to improved speed and fuel savings. These sails can be adjusted for optimal angle and performance under varying wind conditions, making them suitable for various types of vessels. The integration of wing sails represents a shift towards more sustainable maritime practices, as they harness wind energy effectively, contributing to reduced reliance on fossil fuels.

LNG tankers will not benefit directly from sail unless they are better insulated, since they are fuelled by the LNG that boils off during the voyage.
I don't follow your logic.

Oh, you mean because their fuel is a waste product anyway, so there's no savings to be made off "free"?

That’s how I interpreted it. Using the boil-off as fuel makes a lot of sense.

Yeah. Unless they’re willing to add a plant to return the boiloff to a liquid state, or add active refrigeration to the tanks, improving the fuel economy of an LNG tanker is kinda pointless. It’s just not economically sound.
