BAHAMAS 2026: The Recap

Once again, we are fresh off the heels of another great trip with CBD! Our Bahamas trip was one for books!

We landed in Nassau and were whisked away on a shuttle to the dock, where we were greeted by Captain James and his crew. We made our way through the marina to our “home” for the coming week, the All Star Aqua Cat. What a beautiful liveaboard! Our floating hotel was more than we dreamed. The cabins were large, with lots of room to spread out. We quickly unpacked and then set up our dive gear on the dive deck; the one and only time we had to set up our gear for the week. After that, we were ready to dive at any given moment. There was plenty of room to set up cameras and stow gear in our own cubbies. We enjoyed a lovely dinner and afterwards, a detailed briefing about the boat and our itinerary for the week.

Sunday morning came and we were off to a superb week of diving! We saw an abundance of marine life and at least one shark on every dive. Some of the highlights of the week were diving the Blue Hole, Periwinkle Reef, Jakes Hole and the Austin Smith Wreck with that giant grouper that hung around and posed for pictures. And let’s not forget, the Washing Machine (I can still hear the crew yelling, “DIVE, DIVE,DIVE”!!!)! One of the coolest dive sights in the Bahamas, for sure. There were plenty of things to do for divers and non-divers. Who can forget swimming with the pigs and Squishy, the sweetest stingray, who delicately ate right from your hand! There were also hiking, snorkeling and paddle board adventures throughout the week.

Congratulations to our iron divers (those with the stamina to do all 27 dives), those making milestone dives, and a few photo contest winners! The week was awesome! The crew, the boat, and the chef were top-notch. We were truly pampered on the Aqua Cat! It was great meeting new friends and catching up with old ones. All in all, it was a great time, and we will certainly be planning more liveaboard trips with All Star.

Open Water Diver, Now What?
You’re a newly certified Open Water Diver: Congratualations! Here is the point where you might find yourself asking, “So, what next?” Besides starting to dive as much as you can (see Summer Fun Dives below!), we have the top 3 classes to help you grow your knowledge, confidence and skills in the water.

1. Advanced Adventure Diver: The SDI Advanced Adventure course will give you an overview of five different SDI specialties. Two of the required specialties are the Deep Diver and Navigation Diver specialties which are the foundation of continuing diver education. The remaining specialty dives you can opt for include: Advanced Buoyancy Control, Altitude Diver, Boat Diver, Computer Nitrox Diver, Drift Diver, Marine Ecosystem Awareness and many more!

2. Computer Nitrox: Extend your bottom time and increase your enjoyment on every dive. Switch to Nitrox and turn every dive into a longer and more enjoyable experience. By breathing an oxygen-enriched mix, you extend your bottom time and increase the flexibility in your dive profiles. It’s the smart choice for divers who want to make the most of every minute underwater, feel more confident, and enjoy every second in the blue.

3. Rescue Diver: The SDI Rescue Diver Course is comprehensive, covering essential skills like accident prevention, stress management, equipment use, and effective rescue techniques. Expect to learn about diving accident causes, performing various rescues, managing dive-related injuries, and more. These skills are not just about diving; they are life skills that empower you to protect and save lives.
