Most of the fishermen used small outboard motor boats 7.5–9 m
in length, made of fiberglass. Additionally, there are small inboard
motor boats 8–10 m in length, made of fiberglass or wood and
medium-sized inboard motor boats 15–18 m length, made of fiberglass or wood. The Mexican Official Standard for elasmobranchs
(Diario Oficial de la Federación, 2007) indicates that the smallscale fleet is composed of boats 10.5 m long or smaller and that
the medium size fleet is composed of boats that are 10–27 m long.
