Arenys de Mar has a long seafaring indusry and shipyards and a nautical school were built here in the late 18th Century. It is the base for most of the fishing fleet on the Maresme coast and a regular fish auction takes place on the quay. Boats are still built here but they are mainly fishing vessels and pleasure boats. There are many seafood restaurants around the harbour. The Passeig Maritim connects the port with the town`s eastern beach.
