On this trip, were onboard guests from Israel, Switzerland, Spain, Germany, Japan, Chile, Luxembourg and Mexico.

They arrived to our dock in Puntarenas at 2pm and right away we started sailing to Cocos.

The crossing was good and we made it to the island on Monday morning around 2am.

At 8 o’clock we were in the water for the check dive, it was nice and easy with tons of snappers, white tip sharks, lobsters, and couple of marble rays and of course, hammerheads shark.

Manuelita Island was our second and third dive with hammerheads, also tiger sharks were very close and we got people having their first encounter in their life, which was amazing to see how happy they were after that. Marble rays resting on the sandy bottom and the funny frogfish posing for us on the many pictures we took.

Next day on Dirty Rock some hammerheads were getting clean on the station and we got a couple of Galapagos sharks in Punta Maria. This trip we got a swell coming from the west and the visibility was not the best.

Alcyone next morning was unbelievable with lots of hammerheads .We descended and all of the sudden a hundred hammerheads were above us, after this our gest were only interested on diving Alcyone. The sharks were there every single dive we did.

Not only Hammerheads we got to see in Alcyone, we also got black tip sharks hunting, silkys and Galapagos patrolling around.

We made it to the south to Big and Small Dos Amigos, The arch was beautiful with the school of snapers and burrito grunts, visibility also was very good over there.

Night dives were always full of action, lots of chasing as the white tip sharks went after any fish that stayed in the open water , not hiding.This week Chatham bay was the good side with lots of white tips and a black tips hunting as well.

On this trip, our guests Tomo and Hiroko from Japan got 600 and 700 hundreds dives logged!
