Quino el Guardian
Routes: Sister operation to Rocio del Mar with a simpler, expedition-style fit-out, known for hosting citizen-science and research charters alongside standard Socorro and Sea of Cortez trips.
Season: Follows the same seasonal split: Revillagigedo in winter, the gulf in summer.
Character: Science-friendly expedition diving at value pricing
Prices: A modest step below its sister ship, often $2,800-4,000. Research charters reshape the calendar every year; check with the operator for the trips actually open to booking.
Departures: Ports vary by season between the Cabo area and the upper Sea of Cortez.
