? Discover the ingenious Dutch "swords" on traditional sailing barks! ⚓

Did you know that the large wooden boards on the sides of old Dutch sailing barks are called "swords"? In English, they are called "leeboards". These clever devices played a crucial role in navigating the shallow waters of the Netherlands, such as the Zuiderzee and inland waterways. This is why they were essential:

Functionality: Leeboards compensate for lateral drift caused by the wind (known as "leeway") when sailing transverse or against the wind. By lowering the board on the windward side (the side opposite the wind), they provide resistance in the water, keeping the vessel on course.

Adaptability: Unlike fixed keel, leeboards can be raised or lowered depending on water depth, allowing these barks to sail in extremely shallow areas while still maintaining stability and efficiency.

Historical significance:Leeboards were first introduced on Dutch ships around 1570, inspired by similar designs used in Chinese ships. They became a feature of traditional Dutch barques such as the Lemsteraak, Zeeschouw and other flat-bottomed vessels used for goods transport and racing.

Design excellence: Over centuries, leeboards evolved into highly developed components with aerodynamic shapes similar to foils, improving speed and performance and reducing drag.
