Dive Equipment & Rentals

Aggressor diving adventures provides the following equipment to guests:

  • 80 cu-ft tank filled with air using K valves 
  • Weights and weight belts

Tanks with K valves will work with most standard regulators. Each destination has a limited number of adapters (4 - 6) for use. We strongly recommend traveling with your own adapter to ensure your configuration can be used as you desire.  


These yachts accommodate K and DIN valves:  It is not necessary to travel with an adapter:  Cocos Island Aggressor, Okeanos Aggressor II, Maldives Aggressor II, Philippines Aggressor, Aggressor Floating Resort, Red Sea Aggressor II, and Red Sea Aggressor IV.

Rebreathers - Aggressor Liveaboards® yachts are not able to support rebreather diving. Rebreather divers may be accommodated on private charters by special request.

Solo/Independent Diver Diving:   All dives from Aggressor Liveaboards are buddy team dives.  A buddy team consists of two or three individuals. Dive staff are not considered “buddies” unless the guest and dive staff member are the only individuals participating in the dive.

Sidemount Diving - Sidemount is a scuba diving equipment configuration which has diving cylinders mounted alongside the diver, below the shoulders and along the hips, instead of on the back of the diver. For logistical reasons, the Aggressor Liveaboards® will only accept sidemount divers using single tank configurations.

Private Dive Guides & Diving Supervision

Private dive guides are not available. Our goal is to ensure that all guests have an equal opportunity to participate in and enjoy the underwater experience. We aim to avoid providing services that would result in exclusive or unequal adventure encounters for different guests.

We understand that diving is not just an activity; it's a passion for exploring our underwater world. That's why we empower you and your buddy to take charge of your diving experience.  While in the water, you and your buddy are in charge. Every dive begins with a comprehensive briefing from our experienced staff, providing you with the information you need. As certified divers, you and your buddy are responsible for planning and conducting your dives while respecting the limits of your experience and those set by the briefing and your certification agency.

When diving is directly off the yacht, at least one staff member will be in the water offering support, underwater photography and videography, and critter spotting services. On select dive sites, a staff member may assist a group in finding specific points of interest. However, we do not directly supervise dives, and guests are not required to follow the in-water staff member. In some destinations, especially those with tender diving, a staff member will accompany each tender group and be in the water to offer assistance and ensure the group stays together. However, buddy teams can operate independently. If a buddy team needs to surface early, the entire group is not required to abort the dive and follow. The buddy team should follow their training procedures for surfacing from a dive and signaling the tender driver or yacht staff that everything is OK once on the surface.

Today’s compact digital cameras make it easy for first time u/w photographers to capture beautiful images and video. Aggressor Liveaboards offer photo courses and coaching on all yachts by photo pros.
