RIGHT SIDE UP

Yrvind Ten is now on even keel. I turned her with the moulds.

Click once or twice to enlarge.

First time in the boat, plenty of space. The deck starts at the top of the moulds. There will also be a deckhouse, not for comfort, but to give her rightning moment by boyancy the many times when she will be upside down.

The moulds removed.

A close up at the happy boat owner.

As always after an operation there is some cleaning up to do.

Finally one fine day the model got a bit more wind. By GPS she is making 1,5 knots. Speed increses with the square root of the waterline. The real boat is 8 times longer. Square root of 8 = 2,828 multiplied by 1,5 is 4,2 knots. The model with mast spars sails and their supports got to heavy, 3.631 kilos that multiplied by 8 cubed gives the full scale weight to 1859 kilos. That is plenty of spare capacity.

Do not get excited at the speed. Down the roaring forties there be pleenty of storms headwinds and calms and all kinds of truble. If I can get an average speed of two knots I be happy.

OUTSIDE LAMINATE DONE

The outside laminate is now done. For that I needed help. It took some time before frends of mine from all over Sweden cold come on the same day. This is an important step becouse now I can take the boat out of the mould and turn her around and make her mobile for the first time. Click once or twice the  pictures to enlarge them.

This is the boat before the start.

Here the crew are almost done. Everything went very smouthly. After four houers we finished. The new NM-epxy  625 with its excellent wetting properties and exteremly long open time made work easy.

The peel ply is coming on. Captain Thomas closest to the camera. We sailed an old Albin Vega from Sweden to Florida. We have now also written a book about the venture, to be published 27 of August.

Job done. The crew pose for a group picture. From left to right, Beppe webbmaster, Yrvind, Peter Ohlman son of one of my class mates, Jonas has built and sailed a boat to my design acraoss the Atlantic together with his wife Ingrid, Jerker from  TBB Finance group, he works in the same building and is always willing to give me a helping hand, Monica Ohlman, wife of my Class Mate. Mattias small boat builder from Västerås, the above mentioned Captain Thomas, finally Lars Ohlman, my class mate from childhood. I thank them all for an excellent job and for having survived my bossing.

Laminating done.

Today I have done a bit of cleaning up and peeling the peel ply before the NM-epoxy sets to hard.

Last week we tried to sail the big model. There was no wind. Tomorrow we hope for some.

YRVIND TEN LATERAL AREA AND WEATHER PATTERNS

I have not expressed myself clearly. This has lead to misunderstandings by Manie B,  Angelique and probably others. It may therefore be of general interest to elucidate some points.

My models are giving me ansvers to two questions. Can a boat that heavy and so short be driven by a small sail area. The ansver found is yes. The next question can a small boat that heavy and fat and beamy be directional stable downwind, – uppwind it is easy. The ansver again found is yes.

I am the designer, the builder and will be the Captain of Yrvind Ten communication between these differnt doers do not have to be with paper. There are many things to do. Therefore my models do not show all the details.  It definitly would be better to do proper calculations and have proper drawings. It would be safer way, but it would be more boring and take more time. Therefore the model has no foreward lateral area. The real boat will have that, probably a pivoting centerboard. I have good experience from my own boats and from boats I have designed for others. Several ones have crossed the Atlantic so equipped.

Two times I have spent six months in the roaring forties in small boats. That together with extensive reading and talking to other sailors have given me a good idea of the weather there and there is a lot of missunderstanding.

It is a completly different weather pattern if you are a stationary observer or if you are moving with the weather systems like the clipper ships or the Volvo racers or the Vende singelhanders. If you are moving with the wind at from my point of view very high speed you will get a lot of westerly winds. If on the other hand like Yrvind Ten you move at average two knots you are almost stationary and you will get a lot of easterly winds, not only light winds but also gales. I once lost 150 miles in an easterly gale laying to sea anchor. I do not belive in them anymore. They are for boats that have a fear of capsizing. If you do not mind capsizing keep sailing against strong winds.

There are on the average two or three low pressures coming up from the Antartic each weak with very cold winds. The stationary observer will experince north west winds that will go anticlockwise to south west and the turn to light easterly. But other winds will also happen. The roaring forties is not a strong trade wind, not for a slow mowing boat. A slow mowing boat will experience a lot of windward work and need an efficient lateral area for and aft.

SHAPING YRVIND TEN AND 1/8 SCALE TEST

There has been some progres. The hull is now shaped. First I used a Festool power planer to get the rugh shape, then I used longbords muscel powered first grain 24 then grain 60 finally the finishing touch with a Festool rotex orbital sander. The wedges made a good fit. On a few places where seweral wedges met i drilled a 20 mm hole and pluged it with a Divinycell plug. The load waterline at 1500 kilos and the centerline are marked.

I have also tested the big1:8 scale model, she confirmed the results from the 1:20 scale modell, that is, I am on the right track. I will improve the down wind performancet by making two more positions for the masts. The added new positions will be, side by side, forward of the hatch, one on each side of the deckhouse. Keep it simple they say. Sometimes an improvement can be worth its complication. Plankton breed by dividing, we breed by sex. It sure is a complication but might be worth it.

The more I work with Yrvind Ten the happier I get. Of course the project is ridiculus  but so is plying golf and climbing high mountains. What counts is to do something difficult. That is whats makes a project wortwhile. We human beings are the only animals being bored except wild animals in captivity. Wild animals are happy without entertainment, spices and modern conviniences. You get happy by working to your limits, not by going fast, slow down and happiness will catch up with you.

The next stepp is to laminate the boat. For that I need a few freinds. Male or female young or old do not matter. Important is If you have a positive interest in small boats and are handy and careful and like to lend a helping hand. If so call me at 0490 21530 between 20 and 22 houers any day. The lamination is planned to take place preferably a saturday, the 12th or 19th or torsdag 17 kristi himmelsfördsdag in Västervik. There is no pay and you will get your fingers dirty.

The publishing date for my book is getting close I have to work with the by my editor Malin revised manuscript that will also take some time.

COMING NEW BOOK IN SWEDISH

The book is about a voyage in an old Albin Vega with a 19 year old student from Sweden to Florida 2007. The translation of title is: The young, the old and the sea. It will be published in August 2012 at Norstedts, Swedens oldest publisher.

MY BUILDING METHOD

The boat is unique. I have therefore developed a unique building method. To get strenght, boyancy and insulation for the southern winter combined with as low weight as possible I have chosen a sandwich core of 40 mm ( nearly 2 inch ) Divinycell foam of 100 kilo per cubic meter density. For a non-stop sail of one year the boat has no other choice than to be heavy. A heavy boat with a lenght of ten feet or three meter must have very compund curves with small radiuses. There is no other choice. It is impossible to bend that kind of Divinycell into that shape. I did not even consider it. Instead I chose the bricklaying method, building the boat of small bricks or tiles or quadrangels of Divinycell.

I divided the endships, fore and aft into a number of quadrangels. I took measures from the moulds. Of course a quadrangel can never be trusted therefore they were turned into triangels always reliabel. Measures were taken as good as possible. A pattern was made. The pattern was tried for accuracy and corrections were made, then the Divinycell quadrangel was cut out and hold in place with temporary scruvs. Then vedges were glued betveen the quadrangels, held in place with nails untill the glue set.

When the glue had set. Nails and screvs are removed. Next step is to shape the foam.

Here follows some pictures. Click on them once or twice to enlarge.

DIVINYCELL

The hull is now almost completely covered with H 100 4 cm thick Divinycell. Due to the small radius and compund curvature I have had to cut it upp in small quadrangels and build like I was a bricklayer.

A LEAFLET

During the Stockholm boatshow I handed out about 11000 of leaflets. That was 4 every minute. I also gave 4 lectures.

Some people did not like the text, but many did. It is impossible to please everyone. Besides it was not my intention to please anyone but to explain my motivation. Below is an translation:

YRVIND TEN
I have committed myself to sail around the world non-stop in a ten foot boat. The route will be East-about, South of the big capes. I will spend one year at sea on the world’s stormiest waters. 400 kilos of food and 100 kilos of books will feed my body and soul. I call my project Yrvind Ten.
People say it is impossible. Who cares? It is not the first time people have discouraged me. Despite sceptics I built an ocean going sailboat in my mother’s basement. Despite them I invented my own sextant no bigger than a fingernail.
Unlike other sailors I am not in a hurry. I do not want to reach the next port as soon as possible. On the contrary, I am looking forward to spending a year at sea. I consider that this attitude makes my chances of success extremely high, at least 50 %. But it will not be easy. That is the point. For me there is absolutely nothing worth doing as much as solving problems.
To solve problems, to invent and create, consists of combining elements of construction in new ways. Even a few elements give many possibilities. For example, you can place six people around a dinner table in no less than 720 different ways. With one meal a day it will take two years before a seating plan gets repeated. For a group of twenty-four people the number of combinations increases to six times ten to the power of twenty-three.
This is remarkable, because even if you made a thousand rearrangements every second you would have to continue a thousand times longer than our universe has existed before repeating an identical seating plan. This illustrates life’s complexity because few real problems contain fewer than twenty-four elements.
Happily one realizes that this complexity guarantees that the number of possible solutions is never exhausted.
Unfortunately, most people are blinded by hidden rules, regulations and conventions. They do not see the original solutions. To do that, it is necessary to leave the beaten track and climb to higher realms on steps made from fundamental principles. Only up there will your vision be clear. Furthermore, faith moves mountains. One must never give up.
My project’s level of ridicule is on the same level as climbing high mountains or playing golf. Chichester and Rose sailed around the world, for which they were knighted. Knox-Jonston, Blyth and James sailed around the world non-stop and were also knighted.
Sailing’s last, big, ridiculous challenge is to sail around the world in a ten-foot boat. When I first read about the challenge and saw the, boats, I said to myself ”I can do that better, and I can build boats that are more seaworthy”. There are not many branches of sport where a 73 year-old man can set a world record.
And what alternatives do I have, with my wretched monthly pension of 500 €? Do I, like my fellow pensioners, buy a TV and a remote control with big buttons, surf the channels and become bored?
If I did that I would lose my form, I would become fat and slow-witted, maybe get diabetes and have a stroke- then they would put me in a long-stay hospital and connect me to a system of life-supporting machines. Chained to my bed, longing for the free horizons, I would suffer hell. I would spend my last decades trying to persuade someone to help me commit suicide.
No, TV is not for me. I must have something to live for, a problem to solve.
Most people misunderstand life. Comfort does not make you happy. On the contrary, comfort is dangerous to your health. It makes you lazy, fat and bored.  It is only by using energy that you create more energy, and it is that surplus of energy that makes you happy and healthy. Happiness cannot be bought for money.
During my planned voyage I will become absorbed in studying small boat behavior in big waves. Likewise, I will make an inner voyage, a voyage to higher spiritual realms, where I will not be alone: 100 kilos of well selected non-fiction books, written by the world’s greatest thinkers, will guide me.
It is not only for my own pleasure that I have committed myself to make this voyage. I am sure that it will in several ways contribute to make this world a better place.
I expect that it will make people realize the fact that a small boat, properly designed, is safer than a bigger one. Bigger boats create bigger and more dangerous forces. They also demand complicated technology. Complicated technology in the marine environment is vulnerable. Only in a small functional boat do you have absolute control. Only in a small boat are you safe in the ruthless fury of storms.
What is worse and what concerns everyone is that big boats create big emissions that pollute the air and water and that  waste Mother Earth’s limited not renewable resources. That is not only wrong but also unjust. Necessarily, growth has now after three hundred years reached its end. We have already passed ‘peak oil’. They say the market will produce an alternative when oil becomes too expensive. I regret to inform you that that’s wishful thinking. Oil is not produced, it is a finite natural resource that is extracted. There are no economical alternatives because oil is concentrated energy and to concentrate energy is terribly expensive.
For other resources like phosphorous there are not even  alternatives at any price.  Liebig’s law of the minimum proves that lack of one nutrition cannot be compensated for by an excess of others. The example can be multiplied.
Dwindling resources cannot sustain unlimited growth, that’s a fundamental principle.
We must prepare ourselves to live in austerity. My ten foot boat will give me new knowledge. With it I hope to contribute to the small-scale technology that must be developed if we want to survive more generations as civilized human beings.
Do not get angry. Do not kill the messenger. I do this for all our best.

With respect and sincerity, Deep Water Captain Yrvind.

AN IMPORTANT VISIT

Thursday 29 March I met Yachting Journalist Jean-Luc Gourmelen from Voiles est Voiliers at the nearby airport Linköping. Voiles est Voiliers is France biggest yachting magazine. On Sunday 31 March he flew back to Paris. During his long stay here I made my best to show and tell him as much as possible about my past and my planned new project.

It is an honour to have been chosen for an intervjuv in Voiles est Voiliers and I am shure that it will be good for my project “Yrvind Ten”. Hopefully the article will appear in the June issue.

Below is a picture taken of us in Göran Marströms office. Me is to the right. Greatings and thanks to Jean Luc.

Now work on the boat and the 1/8 modell continues.
