A chalupa is not to be confused with a trajinera, which is a boat housing long benches along the edges, and a table through the middle, and poled by a standing person.
These boats are typical of Mexico City's Xochimilco channel and are frequented by local families for weekend picnics on the water.
Chalupas transit on the same channel offering food, beverages, or even live music trios to the trajineras.
The mid-16th century chalupa used by the Basque whalers was 8 metres (26 ft) long, and would have been manned by a steersman, five oarsmen, and a harpooner.
One such chalupa has been given extensive conservation treatment, and as of July 1998 was on display in the visitor centre of Red Bay National Historic Site of Canada.
