Cassiopeia leaves Aggressor Fleet

posted in: Fleet Updates | 0

To our friends and beloved customers;

Cantamar Liveaboards (BCS Buceo y Servicio, SA de CV) a Mexican corporation who owns and operates the M/Y Cassiopea SCUBA liveaboard ship, has decided to leave the agreement with Aggressor Fleet, which was in place since 2017.

Effective immediately, the ship formerly known as “Socorro Aggressor” will recover it’s original name, “M/Y Cassiopeia”, and it is programmed to resume trips to Socorro Island and Revillagigedo beginning from December 18, 2022 as trip demand resumes.

This was a hard decision but a necessary one. The weakening of the US Dollar, rising fuel prices, the cancellation of Guadalupe island trips and other factors created a perfect storm for us not being able to comply with Aggressor’s SOP.

M/Y Cassiopeia is a full-service liveaboard ship that complies with all Federal, State and Local laws, along with National Park, Safety, Navigation and Health certificates and that has received full hull overhaul on July, 2022 and IT IS in good working conditions ready to sail as soon as this week.

We thank Wayne, Larry, Anne & Tom from Aggressor Adventures for all the support and commitment towards the operation of Aggressor Fleet in the Mexican Pacific, and wish them well in the future.

If you have a reservation for Socorro Aggressor and wish to continue with your trip contact us immediately at or via WhatsApp at so we can begin a reservation process for your group, prices and commission structure will be honored.
