Carrancas

I took a "day off". Instead of building my boat, I took a couple of friends for a tour around town. Milo, a young Swiss-American, son a friend, my pal Jonas, and his friend José Felix, from Colômbia. Four "gringos" making a tourist gig around town. Being born in Rio I'm not a gringo, but I look like one, so, ... can't argue against that.

We made a quick sighting of an exposition about "Carrancas" from the São Francisco River, at a Cultural Center (Correios). Carrancas are bow-figures, used by cargo boats of the São Francisco. They were thought to drive away the bad spirits of the river. The utilitarian craftmanship has often developed into an interesting sort of art form.

World Cup 2010 - South Africa

Brasil is preparing for the upcomming World Cup. Games and odds are being dicsussed, and streets are receiving decorations. Employees in the companies are discussing how the work schedule will be organized. Television sets are being installed in strategic areas so that people can watch the games. An exciting atmosphere is developing in the streets of Rio. A sparkling anticipation promised by the world games. It is the only period I actualy enjoy watching futebol games.

I'll post a series on street decorations.

Ukulele play



This video is a nice demonstration of how fascinating it is to watch a musician, who has absolute control of his instrument while he plays his music.

I found it, thanks to Kiko, who has linked the video on his FB account.

Sordid details

During my SouthEast Pacific trip, I had opportunity to live through the most various types of new experiences. In my opinion, obviously, it is these sort of experiences that add the spice to one's life. And therefore, in that sense alone, the travel and all its hardships, were outrageously worthwhile.

Interestingly, some things that seem hideous to some, went past me without much fuss. Take the dress code and washing habits.

As we sailed into the Roaring Forties, which is past the 40-iest, Southern degree of latitude, winds are usually above 25 knots, and the great ocean rollers, often with a swell higher than 4-5 meters, speed past interminabely. After a while, one only really takes notice of them when they grow to 6-7 meters. Temperature can get over an agreable 15 degrees Celsius, in the sunshine. But mostly it's overcast, with temperatures around 10 degrees. Nights were chilly, often being cold, around 5 degrees, making our 3 hour night-watches into a sometimes freezing experience.

Being an bloody amateur in oceanic crossings, my garment was not very well sorted, in my opinion. However, I had the great advantage of having a proper sailing foulweather gear, with waterproof pants and a jacket with a sailors' collar and hood. It was a gift, given to me by my mother, many years ago. Here is one well used gift!
Else, I would allways use; Two pairs of socks, underwear, a pair of cotton training pants, two cotton T-shirts, one cotton or sythetic fiber long-sleeve shirt, a fleece-pullover, a pair of neoprene sailing boots with a proper sole, and my light foulweather gear. The boots were also a well remembered item, lended to me by my brother. He later gifted them to me, and I still have them. Never use them on the boat-building site, though.

During all times while on deck we would carry our harness with teether locked onto something. At night-watches, I would allways carry on me; a waterproof flashlight, and a pocket knife. After a while, I also learned to allways carry on me a pair of cotton working-gloves. The cheap stuff. I've bought them for R$ 5. They saved me many a cold night. And after 2 weeks of use, they get really soft too, if you try to keep them as dry from salt water as possible. If you observe the image in my last post, you'll note, that I also had a woolen cap. I still love it.

I'm afraid I have to say, that my crewmates were not as well equiped as I was. Most of them had barely ever sailed before, and knew not what expected them. Mike, the Canadian, had a outdated yellow oilskin jacket, and synethic windcover pants. Sometimes I offered him my jacket. He rarely took it. Though Canadian!

Daily hygiene was resolved with a rigurously controlled dosis of one cup of sweet water per person. I was surprised to see how well I coped with that one! No kidding. I mean, that I used it very efficiently. I held a very rigorous hygiene routine and had, therefore, no skin or other health problems.

On the other hand, you could serve yourself from as much salt water as you whished for. Eventhough, I tryied to keep far from it. The temperature was not tempting and the salt would cause discomfort on the skin in the long run. When working on deck my weather gear sheltered me from the water. Another reason for the absence of skin issues during the trip.

My experience as a skier and snowboarder was valuable. This included garment preparation, and operational dressing techniques; like using in layers, undressing as soon as possible, and peeling off when working and sweating. But also, the experience of being cold for a few hours.

We had a routine of rolling watches. Each crew member would be on watch for 2 hours during days and 3 during nights, the captain was not included ,and we allways had one free crew member. My preferred watch was in the early morning hours and day-break.

Standing a night watch, alone under an endless stary night, chilling in the endless vastness of the Southern Ocean, is one of my most memorable memories. I will never forget how that feels.

Commitment

One of the most valuable learnings from this boatbuilding project, is the ability to commit. The commitment comes in several aspects. Of course there is the personal commitment to the project itself, with consequent investment in time, effort and such.

But also on a floorshop-level, commitment is needed every time I glue a piece into place. I need to be confident enough to believe, that I have considered all aspects and consequences of adding this piece to my boat. Postponing this sort of analysis and decisions can retard the conclusion of the project immensly. For now I have been successfull with my decision taking processes.

This weekend I have finally mounted and glued the second track for my main hatch. At this opportunity, I also glued on the lateral "finger-savers" (upper left corner, in the picture above). The whole assembly works and looks fine. ... At least it looks easy to my eyes.

I have also glued on the rear window frame. A piece of 4mm plywood worked as a mock up for the policarbonate, for a first trial. This easy window concept works like a charm, and I'm very happy with it. It is simple, cheap, versatile and light! To increase structural strenght, and to pimp it up slighlty, the frame is adorned with copper nails, as on the fiddles on the navigation table.
Interestingly, the wood used on the window frame is the same ply used on the construction of the hull. It will be conforting to have a piece of it clearly visible. Mind you, in the picture above the whole thing is sanded.

55 knots

Weathering a 50 knot storm in the South Pacific. Gusts peaked at 55 knots, and we had 40 knots sustained for 3 days. At more than 1500 miles from land, no mistakes are alowed, when it is blowing a 50 knot breeze, at a temperature of 10 degrees Celsius. Despite the hardships and tension, I enjoyed it immensly. A great, sobering experience.

I felt tempted to post this photo, while browsing through old image files. I have one folder, named "Personal Logbook", which contains varied pictures, impressions of my past.

In fact, this is an image from the files. I have posted the whole story a year ago, in May 2009. It is a passage from my visit to Easter Island.

Amok in Guyana

Picture taken in Lethem, Guyana, in one of the heavy duty trucks, used for transport to the capital, Georgetown.

We had been tempted to drive to Georgetown, using the only dirt road. But we were advised, that our Landrover Defender would not be able to cross the roads, which were softened by weeks of rain. Only heavy duty, 4x6 trucks, with immense tires, were used to establish a connection to the capital. We also refrained to fly to Georgetown, with the national airway Air Guyana when we saw their wind shaken office building, which mas merely more than a shack.

Lethem, the small boarder town, was barely more than a loose gathering of houses, which make you feel like in an english movie, with settings in colonial Africa.

Currents


A Canadian researcher has built a model which allows him to simulate the development of ocean's currents on our globe. This is not a very easy task considering that our planet is a shpere, which spinns around its own achsis. Variations in tempreratures and obsatcles given by landmasses are additional complicators to this model. But it seems that he has done a fine job.

What has brought all this to my attention, and I'm not too much of a friend of complex mathematical models, are the interesting images that the model produces. Like the one above.

Domingo no Parque

Sunday offered us a bright sunny day, perfect for a walk in the Botanical Garden.

Closing in on the ama

Miguel came by this weekend, to see the boat and to talk about a few issues regarding the construction of the ama decks and aka-connection-structure.

It was good to gauge the proportions, volumes. Above a nice portrait of Miguel, holding the ama cross-section. The ama-deck is located on the hight of the indentions.
I also experimented with the path for the steering lines, evaluating angles and such. I'm happy to confirm, that I need only one set of pulleys to direct the steering-lines. This increases overall sensitiveness of the system, to what is happening with the steering-blade, in the water.


I have also varnished some parts. I'm not to happy with the result so far. I'm still getting the grip on my varnishing skills. Thankfully, I found a dedicated article about varnishing techniques, in the "Classic Boat Magazine".

Wisdom of the day


"We may not arrive at our port within a calculable period, but we would preserve the true course."


By Henry David Thoreau, from Walden, 1854

Patin - Puuure sailing

Since the beginnings, my boat-development and -building project, took me to the bounderies, to the more excentric ideas and developments regarding boat design, construction and use. I simply love to see and learn about the colorfull fleet, of those considered more ethnic boat-types; tacking outriggers, catamarans, trimarans, quadrimarans (!), canoes, rafts, proas with dimples, crab-claws, sprits, triangles, no rudder steering... and so on it goes. It is stimulating to imagine the applicability of each feature, to imagine the sailing conditions of bays and lagoons in far away islands. All this sparcles my creativity and imagination much more, than the plastic-white uniformity of todays production boats.

Despite my research and participation in specific discussion groups (proa-file and other), I have never come across this small beach catamaran from Spain, called Patin. It is light and narrow, and features no steering device. No rudder, paddle, board or such. Steering is done with sail-handling and tunig, and a ballet of body weight shifting. The platform between the hulls features 4 of 5 broad beams, on where the skipper literally dances from bow to stern, as required to maneuver the boat.

Moreover, the patin class seems to have a numerous and active racing fleet. All body-steering fans should revel when watching this.

See what they say about it themselves:

"Pati Catalá, that is the actual name of this proa. It took many years to develop it: at the beginning of the 20th century, swimmers at sea were accompanied by a small rowing raft built on two floats. During the development into sailing proa, the rudders and boom were not added yet: that is how a very simple vessel with excellent sailing qualities was created. In the meantime, the Patin has grown into one of the largest unity classes over the whole region of Catalonia. Along our coast as well, especially in De Haan, we have been able to admire the gracefulness of sailing a Patin since the seventies."

Fancying th Nav Table

My navigation table is getting to a finish. I've got 3 coats of epoxi on it, and will now cover it with varnish, for UV protection. For strenght and fanciness, I have nailed the fiddles with copper nails.

Against forecast, the Saturday was bright and dry. I did some epoxi-ing and gluing, but in total, I was unefficient this week. I'm stuck with scheming out the various elements of the cabin. First and foremost the steering mechanism.
As can be seen in the lower picture, the nav table will also serve to blind the front window.

Diesiger Morgen

The atmosphere is full of moisture this morning. I hope that the sun will burn it away later today. An excess of humidity might spoil my plans of using epoxi and varnish. But I have no high hopes, since the forecast is not good. Lots of rain is likely to fall today and tomorrow.

Tomorrow we will have an air race, here in Rio. They will fly a race course with obstacles over the Guanabara Bay. And I plan to see it from the top of the Sugar Loaf. I can already hear the engines of the airplanes, which are probabely training.

300 manhours of work in one year

Have you ever wondered how much work you can get done in roughly 50 days? If in those 50 days you average 6 workhours, than that would make 300 manhours.

Well, here is a good picture, of how much I have achieved myself. On the first of May 2009, I had just turned my boat, and was about to start sealing the interior, build deckframing, decks and cabin. An I am not quite done with it yet, as you see below, a current picture. ... Looks simpler than it is...


If I think about it, this 300 hour estimation doesn't count the hours of others who have helped me along the way...

Spacequakes

An interesting phenomenon is causing a natural lightshow to those who live in high Northern latitudes, and it also has an interesting side effect.

Strong Solar eruptions cause eletromagnetic discharges, which crash into the Earth's magnetic field. In the process they cause the known phenomenon of the Northern Lights. What was not so well known, is that, in case of exceptionally strong solar eruptions, the Earth's magnetic field also starts shaking and vibrating. Sensible magnetic needles, like in a compass, could pick up the swinging and vibrate as a result. The magnetic vibration reaches out over our earthly bounderies, right into outer space. Which is why researchers are trying to establish the word "Spacequake" for this occurance.

If you are a sailor, relax. Your navigation will probabely not be affected. Unless a solar-wind storm takes out a GPS satellite... But if you are travelling in a spaceship, it might be time to plan you escape routes...

Bird nesting

I didn't really feel fit on Saturday, and didn't therefore have a very productive day. But that is allright. Finishing takes time.


Cairú II

Eduardo H. Regua is doing a great job in getting Cairú II, the Class Brasil from 1949, back into original shape. Doing such a preservation job here in Brasil is not easy, since materials and equipment is not easily sourced. My congratulations to Eduardo! I'll be thrilled to see Cairú sailing again.
One of the many good things Eduardo is taking care of, is that he has given the boat its name back. But apart form that he is going great lenghts to achieve an close to original state, including wooden blocks.

Starship

The other day someone commented that my boat reminded him of a starship. He mentioned the "Millenum Falcon", Han Solo's ship in the Star Wars trilogy. To my amusement, it has not been the first time that such sort of parallel has been pointed out.

As a kid from the 70-ies generation, the Star Wars trilogy, of course, had great influence over the formation of my pictorial memories. As a boy, I have lived through great adventures in imaginative starships, travelling trough distant constellations. As I got older, I have found that our planet offered plenty of real world adventure. A great, gigant playground.

But the design of my boat, I assure, has nothing to do with that. It is the result of quite different ponderations and constraints. Immaginative deep space is a much more benign environment as our real, earthly Oceans. My boat has been designed to transport me safely over the sea, in any condition encountered in the realms of the South Atlantic, down at the Tropic of Capricorn.

Discovery

One thing I love about sailing in Rio, is the feeling when the bow is pointing back towards the Bay entrance. The view over the Sugar Loaf, the range of steep, green hills of granite rock, mesmerizes me. Something about this view takes me back into the ages of discovery, when sailors set into the sea, sailing right into the unknown, to discover the secrets of distant shores.

The image above was sent in by Mistralis.com - they organise sailing programms around Rio, and all over Brasilian shores.
