Dockside Costa Rica

The wind has been blowing these last couple of days, a casual 30+ knots, meaning we’ve sadly lost the ability to have our shade up (pity Jake and myself with our ginger tendencies). That is not to say the breeze isn’t welcome! I have been compulsively checking the forecast in the hope that the equatorial trough takes a long-deserved break, which would allow us to sail all the way to Cocos. Shockingly, so far no luck, but at least we’ll have a good sail to start the trip off.

Unusually for 59º North, arguably the real pull of this next trip isn’t the sailing, but the destination — a UNESCO World Heritage Site, Isla del Coco, also known as Island of the Sharks. The 24 km island is a 305-mile trip into the Pacific (requires a fair amount of zooming on a map to spot), was the inspiration for Jurassic Park, and is one of 11 conservation areas in Costa Rica. Jacques Cousteau described it as the most beautiful place on the planet and it is considered one of the top diving destinations in the world. Whilst we will be snorkeling rather than diving, with such an abundance of marine life — particularly pelagic species — I don’t think we’ll be disappointed. On land, as befitting of the place that inspired Jurassic Park, evergreen forests, waterfalls, and lookout points are there to explore. It is one of the few pristine places left on Earth, and it is a very exciting privilege to visit!

Cocos is located only 5 degrees above the equator, so as expected the wind will be fluky and variable, and there’s a good chance of rain as we journey south. We will be going like a bat out of hell when we depart Guanacaste, with the Papagayo winds giving us a good push — even better, for the first time in weeks we’ll be sailing downwind!! We plan on hugging the Nicoya Peninsula because I’m STILL not done talking about the Tehuantepecers. They are absolutely hooning at 50 knots right now, and whilst I’m not planning on popping back north, the NW’ly sea state they generate will be making its way down south and crashing into the NE’ly swells from the Papagayo winds. If we were to follow the most wind and curve down with the Papagayos, then it would be a horrendous confused sea state, and I like my crew to not be green in the face. Instead, we will plan for a more uniform 2–2.5 m swell whilst still able to utilise the stronger breezes, by initially sticking closer to the coast. There are also currents to consider, which I will save for another blog.

The crew have been brilliant, soaking in all the briefings so we are able to set off as soon as possible in order to get the most time at the island and allow for some not-so-speedy light wind sailing. Today is Matt’s birthday, so Adam has donned one of his many hats and baked a chocolate cake, much to everyone’s delight!

Quadruple digits!

We are still headed north away from Hawaii, though today we have started to veer ever so slightly east. Speaking of miles, we hit quadruple digits today and are currently 1051 nms into our journey to Alaska. The sea state continues to calm down, and the famous North Pacific high is just out of our reach. The next few days will be a delicate dance of riding the outskirts of the high while avoiding the pesky low pressure systems that are dancing nearby. In his very wise words, we need to get north but not too far north, stay south but not too far south, continue heading east but not too far east, and avoid going west but also stay west.

The basics

Nordic Falken and her crew have been in a steady course of NNW since the departure of Hawaii. But! The good thing of all of this is that the promised land on which the high pressure lies has been getting closer and closer, meaning in a couple of days we're gonna see the wind slowly veer all the way to the South, which finally should see us easing the sails and remembering the basics of human nature all over again. The crew have been amazing and we've had everyone come around to push through fatigue, seasickness and soaking wet clothes. On another note we left the tropics a while ago and we can really feel the shift of temperature, long gone are the shorts and foulies have been the norm. Not much more apart from this, my intolerance to upwind sailing still pretty much alive but doing it with a bunch of such amazing human beings makes it worth it worthwhile.

The basics

Pacific pace

After some initial adversity, we untied our lines and left the beautiful island of O'ahu behind as we set sail north on an adventure of a lifetime. And that is exactly what we are - a family of strangers brought together by a passion for sailing and a love for the sea. The passage, while at its infancy, has delivered. The wind and seas, stars and sails all set the stage for a fantastic journey. We will see you on the other side with many stories to tell.
