My first Aggressor trip was Fiji in 2009, the trip was fantastic, the boat and crew wonderful, we even had a tsunami warning and the recall was handled very well, everything explained and missed dives were offered later in the week. My next trip was on the Cayman Aggressor, it was enjoyable, however a few items were of a concern, the advertised scooters are not available to guests because the Captain doesn't want guests to use them due to complications; but does approve of himself spearing lion fish and feeding them to a couple frequent visiting sharks, guests were not consulted on our opinion of this feeding activity. There was a bit of a feeling of 'been there done that, we know what we are doing'...but all in all, still a decent trip. The same year aboard the Okeanos was a different story. Ship is in poor state of repair with bolts coming out all over the deck; air conditioning in the main salon eating area not functioning; beds with very thin foam for a mattress with a 40 plus hour rough sea crossing this was uncomfortable. There were no rinse tanks provided and guests are frowned upon when using deck showers that might rinse off gear in anyway; dive operations were not well managed, we had a diver go missing, no protocols were followed, our divemaster abandoned a dive after all divers had descended, free ascent into the blue by ourselves hoping for the best. The meals were very below average; spaghetti three times, chicken legs three times...not up to the usual standards of Aggressor. Unfortunately, we also had a frequent flyer on board who was very cosy with the Captain, so much so that we all got a nice moon shot when he was showing her his goods....not to mention she did most of her dives chasing away everything, which was not addressed the entire trip. Several guests mentioned concern over rinse tanks, protocol, driving the inflatables with more care, reminding guests not to chase away sea life; all comments were met with a language barrier. This declining experience has sent me to Explorer and Undersea Hunter for my next two liveaboard destinations.
