    This crew clearly lives and breathes ocean conservation and marine wildlife. Manolo stands out across reviews for his exceptional spotting abilities and genuine passion, while captains like Emily, Scott, and Jack get praised for their smooth handling of the boat. Rocky, the marine biologist onboard, brings serious expertise that guests appreciate, and the safety divers demonstrate real professionalism during shark encounters. The team's knowledge shines through whether you're swimming with makos, watching dolphins, or spotting the occasional blue whale or great white from the boat. The marine life encounters are genuinely impressive. Guests report seeing everything from mako sharks and sunfish to multiple whale species, dolphins, and sea bass. The crew works hard to find wildlife and gets you surprisingly close to the action. People with anxiety about open water specifically mention feeling comfortable and safe. A couple of reviews note rough ocean conditions and communication hiccups, but the overwhelming majority describe professional, friendly service and once-in-a-lifetime experiences that justify the trip from out of town or even flying in specifically for these expeditions.

    Had the most amazing experience with net zero. The captain and crew went above and beyond to make sure I had an epic experience. They explored all over to find the bluest water and we spent time with all different kinds of sea creatures. We came upon a pod of dolphins that had to be in the hundreds, saw yellow tail and Swam with mola mola. The boat was awesome comfortable and speedy made for a super nice cruise. I love that they collected any trash we saw as well made my heart happy to know there are ocean warriors out there taking care of the pacific one day at a time. Zodiac is the best way to explore the ocean in my opinion low to the water and fast. How could it get any better. I will definitely be joining them for more adventures whenever I am in san diego. 🌊🐟🐬🐋🧜🏼‍♀️
