The Alliantie Almere Haven Festival is a 3 day event held in the harbor of Almere, the Netherlands. A botter boat race is held on Friday. The Botter is an old Dutch type fishing vessel with a flat or slightly V-shaped plane with a net protruding keel. Botters fished mainly on the former Zuiderzee, but were also used for inshore fishing in the North Sea. The type originated in the 2nd half of the 18th century.
