A trainera is a traditional boat of the Cantabrian Sea coast at the southern end of the Bay of Biscay, propelled by oars, and formerly sailing. It is a boat of fine lines with raised prow and rounded stern, to resist the waves of the Cantabrian sea. Traineras were originally used by fishermen to bring in the day’s catch of anchovies and sardines from sea to market, usually competing to sell their caught fish before others came in. Today, this historical tradition has become a major sport of coastal boat racing.
