Repairings, Capital

We leave Nazaré and head to Lisboa, passing the Cabo da Roca, the westest point of Europe : how pleasing it is to at least sail a bit to the East ! As soon as the sun is up, we hear the moanings of our 3D printer. There is a lot to be done in Lisboa, and we try not to waste any seconds !

3D printing at sea

We have set ourselves a challenge : repair the hydro-generator before arriving on the Tage River. We succeeded, but one of us walked on one of the blades, so we’ll have to print an other !

Once in Lisboa, our concerns are not to hear some fado nor to take the 28th tram : where are the shipschandlers and the repair stores ? How do you say « threaded shaft » or « pulley » in portuguese ? We will manage to find every pieces we look for, but after 48h we haven’t seen much of Lisboa. Hopefully Adrien’s mother is visiting, and gives us pretexts to go visit a few museums.

Our goal in Lisboa is also to visit the different digital fabrication places. We are wecomed to visit the EDP fablab, working with companies and individuals. They have great projects, working at the same time on homemade electronical circuits and doing research on the different finitions possible on 3D printed parts. We are amazed by the work they manage to do being only three in their team ! This warming welcome in Lisboa lets us forget the buses of tourists that continuously make selfies all around the marina.

Visit at Fablab EDP

The fablab EDP team will then come visit the boat, giving us the bottom of a 3D printed blade for our wind turbine, and one hydrogenerator blade !

Fab EDP aboard Karukera

We also go to visit the Leds&Chips Creative studio that has built us 3 parts of wind turbine blade ! They conceived and built an impressive 3D printer that almost makes 1 cubic meter ! They could print our wind turbine in one piece. Being very humble, they named it the « YARR » (Yet Another Rep-Rap : rep-raps are open-source 3D printers). Their studio is filled with numerous of different 3D printed objects at an unusal scale : a woman bust, a stool, a chimera model !

While visiting Karukera, they will bring us the last missing pieces of our wind turbine !

Then it’s just a puzle that need to ber e-assembled, and as fast as possible, so we avoid to pay one more night in the marina !
remontage de la nouvelle éolienne

Black and white gives a good render. We got used to the multicolored version, this one looks more professionnal : we need to be careful !

Mise en place de la nouvelle éolienne

We have met numerous passionating makers in Lisboa, and we want to thanks all of them for helping us ! First Zbis (http://zbis.fr/) that printed us the upper parts of the blades before leaving France, fablab EDP (http://www.fablabedp.edp.pt/en), Leds&Chips (http://ledsandchips.com/) as well as Gino from A Coruña hackerspace(http://bricolabs.cc/)! But after one week stucked between traffic jams, trains and honkings, we are releaved to go ! Inès has gone back to France, and we head to Faro where we will be joined by two new crew-members. The coasts of Algarve and a nice gale are waiting or us !

POTUGUESE MISFORTUNES : FROM BAIONA TO NAZARE

Was Neptune in a bad mood this days ? Or is it just an unfortunate following of events ? Anyway, we got pretty unlucky in the last days…

Weather first blocked us in Baioa under rain pourring cats and dogs, and wind gusts over 50 knots ! We have to spent the days inside the boat, fighting against moisture while trying to fix differents stuffs as best as we can. The moral breaks when we discover that the wind turbine got blasted against the solar panels… Wind pushed the solar panels up, enough for the wind turbine’s blades to crush on it. We did test the room between the panels and the blades, but the wind was stronger than our arms, and the panels went further than we could expect. Half the baldes are now broken, and the moyeu is wrecked. That’s the end for our wind turbine first version!

Eolienne cassée

The next day, a short weather window allows us to leave Baiona to Porto. We still have to face 15 knots of wind coming from South (where we intend to go) and a 4 meter swell. Pretty unconfortable. After numerous tacks, we leave the Cies Islands in the clouds.

Iles Cies dans les nuages

A few hours later, the swell has almost gone, and we pass the Rio Minho outlet : we are now in Portugal ! We set the red and green courtesy flag on !

On hisse le pavillon portugais

We make a two days stop in Porto, fixing different stuffs, printing new blades for the wind turbine, and an afternoon of sightseeing. We leave sooner than expected, as soon as a bit of North wind comes back. The trip ends sooner than expected : with no wind we go to the Aveiro Laguna with the engine. This one produces strange, unhabitual noises, and we discover that some of the fixation bolts are untied.

Réglage des silent-blocks

After a few hours in this place we love so much, the engine stalls, we leave the laguna with the wind and nice sun beams appear to (at last) dry the boat and its crew. We are in a good mood, we fish and start sewing a protection hood against the rain.

Navigation et couture

Leo starts a few experiments to optimize the hydro generator. The problem we have is that the rope between the generator and the hydro propeller has to be unraveled after each use : a long and boring operation. cf video

Le méli-mélo de l'hydrogénérateur

The new unraveling technique is quite simple : You just need to detach the rope and the propeller, and let the boat’s speed unravel the rope for us. To ease this operation, we decide to use a carabiner instead of a shackle. But an unforessen kind of fish opens the carabiner, and we loose the propeller part of our hydrogenerator ! We set a challenge to print the new blades for or propeller before arriving in Lisboa ! The Northernly wind is stable, and we continue to sail south with the spinnaker. While we take shifts at night, the 3d printer prints the new blades for our wind turbine.

Pale d'éolienne en impression

Before dawn, some « déjà vu » strikes again : an other part of our steering wheel cable breaks ! Again ! This time the weather is very nice, and we repair quite fast, installing rope and hoping it will hold till the closest harbour, Nazaré.

Drosse cassée

After a few hours of sleep and a shower to fill our energy, we install a new steel cable and assit to the fishermens parade, all decorated for a sea procession.

Bateaux décorés à Nazaré

We leave before the sun sets down, to Lisboa, beginning to print our next hydrogenerator !

Stopovers in Galicia

After our maritimes adventures, the stop in A Coruña is more than welcome ! Showers, rest and groceries keep us busy the first day. We benefit from the harbour office WiFi to send our videos to our videast partner Olivier La Combe (http://www.echoesprod.com/) who produces the first movie of our trip :

We are welcomed to visit the first lab of our trip at Coruña’s Domus. The Bricolab (http://bricolabs.cc) is hosted at the Galician museum of natural history ! The hackerspace community is very kind to us, and we share a lot with the makers around our respective projects.

bricolabs

One of our problem during first step was on the navigation system we prototyped : they bring the big guns on the next day and with an oscilloscope we manage to find the electromagnetic perturbation. It allows us to receive a hacked AIS signal (a system that localize big cargos and fishermens in the nearby area) : very convenient to sail with low visibility !! Furthermore they give us 40 liters of bio-fuel that they recycled out of friying oil with a homemade device. One of the makers will also give us an educative little robot : #Escornabot (http://escornabot.com/web/) joins us for the mediterranean fablab tour ! The aim of this project is to initiate young students (6 to 10) to the basis of programmation !

escornabot

After those first 700Kms Karukera needs to be checked up. The steering wheel cables are replaced, and Oliver builds an emergency tiller. We hope we’ll never have to use it, but since it’s in the rear cabin why not use it when it’s raining ?

drosse

Leo climbs up the mast to control the differents pulley and rigging cables. Everything checks out after a few optimizations !

check up mât

This stopover was amazing, and we enjoyed tapas and Cañas a lot ! We also met Celine ( http://martineenbateau.com/a-propos/), a boat-puller coming back from an atlantic tour, which was pursuing to Norway. The Boat being ready, we head to the Ciès Islands with Inès, a friend of us who just arrived.

ines nouvelle equipière

The first sailing day is quite hard to begin with : low breezes and big swells make the boat roll over and over again, not good for our stomachs ! A quick stop to Muxia is needed to sleep a few hours, long enough to digest a hot meal ! It was unforeseen that the names around the hull would be the targets of those who lean the head overbord… Sorry to our Kissbankers, but the waves wash the hull very fast !

The mythical Cape Finisterre is surprinsingly calm, offering a wether so gentle, that we can even raze it ! This nice day allows us to enjoy the sunshine and its heat for the first time since we left Pornic. Great smiles are on all faces !

finisterre

We also use this time to fish, and with success ! Three mackerels and one garfish are prepared by Adrien, and we cook good rillettes aboard Karukera !

In a very light breeze, we arrive finally to the Cies Islands at night. Waking up among those wonderful landscapes is amazing ! After canoeing and trekking, we go sail between the Islands while some of us make pictures from the Islands.

This Paradise has to be left sooner than expected : a gale is in approach, and we head to Vigo to find shelter.

vigo fait pas beau

Once arrived, despite the rain, we go looking after musical instruments. Oliver and Adrien couldn’t bring their brass, and the frustration grows up ! We finally find a small Yukulélé and a flute ! The stopover has to be shorten up, the harbour being quite expensive, and everything we try to do in the city is a failure. Friends we have met in A Coruña are spending the week end in Baiona, we set sail to meet them !
