2024 – 2025 Similan Islands Liveaboard Season Update

March 22 2024: Thailand Aggressor is relaunching in Thailand for the 2024 – 2025 season! The boat has not been operating for the last couple of seasons but will now be welcoming guests again from 2 November 2024.

There are currently discounts of $500 on trips running in November and December 2024 if you book before the end of April 2024. See the Aggressor’s official booking page for dates and prices with the $500 discount.

The Aggressor lists the itinerary as “North Andaman Sea” and that is the area that includes the Similan Islands and Richelieu Rock. For an overview of what to expect from a Similan liveaboard, see Diving the Similan Islands: A Quick Guide and my recent Similan trip reports from February 2024 and October and December 2023. There’s also a now very old trip report from being on the Thailand Aggressor in its original incarnation for a Myanmar And Similan Islands Liveaboard Trip in 2015.

If you prefer booking through Liveaboard.com their Thailand Aggressor page should be updated shortly with the new trips schedule.
