A renewed invention.

The energy crisis is causing us to once again rescue one of the oldest inventions of humanity, the candle.


Although the sails of the 21st century for the transport of ships do not look like those of the 19th century, they will not be made of cloth and they will not even appear to those of the current sports sailboats, although the objective of the sails that you are going to see is the same, take advantage of the force of the wind to propel a ship.

Of the different experiences that are being carried out around the world in these days, two have made the news, a Swiss franc project and a Spanish sail that is already a reality because it has been installed on a fishing boat, the Swiss franc project is called WISAMO and It is a collaboration between the Michelin tire company and two Swiss inventors.


The original thing about this sail is that just like a tire it is inflatable, its revolutionary design allows a boat to reduce its fuel consumption and therefore have a positive impact on the environment, by reducing CO2 emissions, the sail is designed to be installed on most merchant ships and pleasure boats.

In total, the system can improve the fuel efficiency of a boat by up to 20% and all this in a very easy and comfortable way, remember that one of the problems of the old sailing ships is that they needed many sailors to attend to the complex maneuvers of hoisting, collecting and holding the sails, while one of the many advantages of the steamboats is that they only needed someone to add coal and watch the boiler, but what would happen if a boat equipped with this Franco-Swiss sail had to go under a bridge, the inventors have also thought about that the mast, it is telescopic, retractable this WISAMO system will be installed for the first time on a merchant ship next year 2022 when Michelin expects the sail to go into production once completed the test phase.

The other sail has been developed by the company bound4blue in Spain, in this case the structure looks more like a chimney, but like traditional sails it knows how to use the force of the wind.


The structure has been assembled on a Spanish fishing boat in Panama and it is the first time that a rigid sail has been installed on a fishing boat, the sail will be put to the test during the month of June and the idea has already interested Galician shipowners who plan to extend this sail prototype to the rest of the fleet and thus reduce the fuel consumption of its boats by around 30%.
