Dutch Sailing Barge with Leeboards

This is a Dutch sailing barge with leeboards. The leeboards are used instead of a keel so that a boat with a shallow draft can sail against the wind. The leeward side of the boat is the side downwind or sheltered from the wind. Here is a description of these barges from Wikipedia: Dutch barge.

A Dutch barge is a traditional flat-bottomed shoal-draught barge, originally used to carry cargo in the shallow Zuyder Zee and the waterways of Netherlands.

Originally, Dutch barges were sailing craft with wooden hulls. Today, while few wooden examples remain, there are many steel barges that are 100 years old or more. Although most Dutch barges have been converted to motor-propulsion, schuyt sailing contests are still held on the IJsselmeer and on the Wadden Sea (Waddenzee).

There are several types of Dutch barge, with characteristics determined by local conditions and traditions. Dutch barges have become popular live-aboard leisure craft, and brand-new "replica" examples continue to be built.
