Okeanos Aggressor II Liveaboard Review - Expert Guide to Choosing Your Liveaboard

Russell Bowyer here. I've written this Okeanos Aggressor II Liveaboard review to help you choose the right liveaboard with confidence. As a qualified diving instructor and Advanced BSAC Diver with 500+ dives worldwide, I've helped countless divers pick their perfect liveaboard - whether it's your first time liveaboard or you're an experienced diver seeking your next adventure.

Read more about Russell's diving experience

My diving experience spans cold-water UK drysuit dives, warm coral reefs in the Caribbean, the Red Sea, the Great Barrier Reef, and South Africa. As a former BSAC Diving Officer and diving instructor, I've taught many people to dive and taken a lot of the divers I taught on their first dive. I also used to organise and run dive trips in the UK, with one of my favourites being expeditions to the Farne Islands to dive with the seals. I've logged every type of dive: decompression stop deep dives, wreck dives, shark dives, night dives, drift dives, and everything in between. This hands-on experience means I know exactly what makes a great liveaboard experience, having dived from liveaboards myself and loved it. This is why I came up with the SDE Liveaboard Rating* to help you choose the best liveaboard for you.

SDE Liveaboard Rating – Underwater Photographer Features for the Okeanos Aggressor II Liveaboard

My score of the Okeanos Aggressor II liveaboard is 4/5 on the SDE Underwater Photographer Rating, as it has 4 of the 5 key photographer facilities (see below).

The Okeanos Aggressor II liveaboard includes a dedicated camera room so you have a safe, dry area to build and service your underwater camera rig between dives. In addition, it has a dedicated camera station close to the dive deck, which lets you gear up quickly, check your housing and swap batteries or memory cards between dives.

What’s more, it offers a separate rinse tank for underwater cameras, which is crucial for protecting expensive camera equipment from scratches and damage. Also a dedicated camera tank avoids any risks that can arise from sharing space with general diving gear, such as regulators, wetsuits, and heavy fins to avoid contamitation from sand, salt, debris and any chemicals.

You’ll also find it provides dedicated charging stations for cameras, strobes, torches and laptops so your batteries are always topped up and ready for your next dive.

Customer review from Liveaboard.com

“10/10 would go again. This was a fanstic trip to spend time with my brother and meet new friends. The diving was superb, never a dull dive day. The crew were always willing to help and were very friendly. The chefs and the food were amazing, no doubt I gained a few kilos on my vacation :). Even though some days the weather was not ideal, the crew and the dive guides did their best to still offer the best experience in and out of the water.”

Recommended for: The chef and the food were fantastic! Also very good on accommodating dietary preferences. the diving and the dive guides/penga captains were great! Always ready to help and provide the best service. the crew and other costa rican guests were very hospitable to us and made us feel welcome in their country..
