Chatham Bay, Isla Del Coco

I am writing this as we sit on a mooring buoy in an idyllic bay in the middle of the ocean. Roughly 5 hours ago we arrived at Isla del Coco and promptly jumped in the allegedly shark-infested water for a quick dip. Everyone will be pleased to know we were very sensible and sent Nic in as a guinea pig before committing the whole crew — even better news is that every crew member still has all their fingers and toes. In fact, no sharks have been sighted yet, but I am sure that will not be the case for much longer!

It is beautiful here. Jacques Cousteau may have been onto something. The only slight complaint we have is we would like it to be less rolly, if possible! Lee cloths may need to be up tonight, but I think everyone is looking forward to a full night’s sleep.

We haven’t had contact with the rangers yet, despite multiple radio calls. However, a friendly dive boat swung by and offered us internet for one phone, some stickers, and maybe an opportunity to dive here. Regardless, where they dive is mere meters from our boat, so some good snorkelling is definitely on the cards. The diver, Roberto, used to be a park ranger on the island for 9 years, so we’ll be taking him up on his offer to help with anything!

Hopefully the rangers pay us a visit in the morning and we can get to some real exploration. In the meantime, we’re having a lovely time star-gazing and enjoying our moonlit view of the island (see pic!).

Dolphin party!

Kate was about to yank the spinnaker’s sock down when I spotted a stampede of fins heading straight for us. ”Dolphins!”, I yelled back to the cockpit excitedly. Post dinner dish duty was halted down below for the show.

The pool is open!

We stopped the boat, got the ladder down and put out a line with a fender behind the boat. I love swimming in the middle of the ocean, and a bit scary when you realize its more than 4000+ m deep! Love it!

Big Pink Sail Day

I had a most fashionable pointed striped hat at dinner, and out of the depths of a cupboard a cake was created, after 14 days at sea. A group of people I had never met two weeks ago made me feel very special today.
