Advanced Wreck

with Hydronauts


The Advanced Wreck specialty course is designed to extend your knowledge and skills of diving to allow you to dive in and around wrecks environments, including entering and penetrating wrecks. The course develops the knowledge and skill set required to properly plan and prepare for wreck dives by understanding and mitigating the risks involved. 

Training is conducted on our resident shipwreck, the HTMS Sattakut resting in 28 meters of water. A former US Navy WWII vessel, she was donated to the Royal Thai Navy and then intentionally sunk in June 2011. 

To allow maximum bottom time and NDLs, we recommend having completed your Nitrox course prior to taking the Advanced Wreck Course. It is more difficult to complete the required skills on the HTMS Sattakut while diving on air.

Online Study

Your training starts online where you will access all your RAID training manuals and quizzes. Contact us to get started with your e-learning before you arrive!

Step 2 - Theory & Workshops

On arrival, you’ll meet your instructor who will review your pre-completed e-learning with you. Your instructor will conduct a few workshops on history of wrecks, equipment, safety procedures, dive magangement and safe diving practices to help you get the most out of your learning experience.

Step 3 - Pool Training

There are two sections in the Advanced Wreck confined water or pool training. First, you‘ll concentrate on buoyancy control with a particular emphasis on weight distribution, propulsion and monouvering. The second section will focus on practicing various line tie offs, lost line drills, alternate air sharing skills, and other malfunctions recovery procedures in preparation for the open water wreck dives.

Step 4 - Open Water Dives

Before we start to penetrate the HTMS Sattakut, we will practice the skills and techniques you learned in the pool in open water. We believe repetition is key to increasing muscle memory and thus confidence.
We will carry out 4 open water training dives which will harness your buoyancy skills and prepare you for going into the overhead environment.
This is a fun course where we will practice putting you under stress in a controlled environment, allowing you to handle yourself in any scenario.
