Manufacturer's plate of a Breizh Gazelle

Every pleasure craft is required to display a builder's plate indicating the WIN code. Here are the keys to deciphering it and understanding who actually built the boat and took responsibility for its compliance.

The WIN Code: an obligation to know the boat's builder

All pleasure boats registered in France and in Europe are obliged to carry a WIN code permanently and unalterably. This sequence of numbers and letters may seem abstruse, but it makes it possible to know the name of the builder, the country of production, the age of the model, the year and month of construction. Important details, at the time of purchase, to ensure the good faith of the seller. "It is wise for the yachtsman to make sure who actually built the vessel. Especially in the case of dealers who present customised boats on site for example or for second-hand boats" explains Xavier Nicolas, director of the Maritime Affairs yachting mission.
