EXLEX THE IDEA

THE IDEA

My idea is to create a good cruiser. I like her to be small, simple, have shallow draft, be trailerable, be propelled by sail and oar.
For me this is an interesting design and building problem.
An interesting test would be to trail her to Ireland or Norway then sailing south and doubling Cape Horn.
For many the ideal cruiser is a well equipped fifty footer. The prise for such a boat ready to sail is abot a million dollar and the yearly running cost about 10 % of that.
The present boat Exlex is a canoe yawl with a bow pivoting centerboard. She will have 84 kilos of lead as mowing ballast.
She is 6.27 cm long, have a beam of 1.4 meter, with a draft of about 0.4 – 0.5 meter.
She will have two freestanding, rotating, side by side, masts with a length of about 3.5 above deck. Each of those mast will carry 3.5 square meter sail area. In addition 0.5 meter from the stern is the mizzen mast she will have 1 square meter sail. In all she will carry 8 square meter sail area, twice as much as the previous Exlex.
Her displacement with food and water for 100 days is estimated to be about 1 metric ton.
I believe my idea is more realistic as she will give more satisfaction, give less worry. One more good thing is that she will use far less of our non renewable resources.

A NEW YEAR A NEW IDEA A NEW ROUTE

A new year a new idea and a new route.

Often small small details have big consequences. Doing the mock up for the dining room I had put, below the seat twelve five liter plastic water cans as part of the water storage. My plan was to do a long sail to New Zealand. Madeira to Dunedin is about 14 000 miles. With an average estimated speed of 75 miles per day it would be about half a year.
There where refilling places on the route, but none really appealing.
To stop in Uruguay would add miles.
In South Africa, there was a lot of traffic it was stormy, there was also much crime I heard.
Australia demanded a visa. I had written to their embassy in Stockholm. You have to call Canberra came response and they have no e-mail. Sure they must have e-mail in Canberra. I realized that they tried to make it difficult for me and got angry.
With just nine cans I would have a bit more space I thought but no decision was made. I could have made the boat bigger but I like a handy boat. I waited for my inner voice to speak.

On my door, way back in time, I had written
Cape Horn East to west. Lat 50 S to 50 S as an interesting alternative.

On the night between 30 and 31 December 2021 I woke and started thinking. There is a lot of depressions passing Cape Horn. I thought if I could make reefing more easy and take advantage of the shifting winds I may stand a chance of reaching the Pacific that way.
Then I came to think of the Ljungström rig.
Navigateur Yann Quenet was using it on his Baluchon.

It has a free-standing mast that can rotate. By turning the mast on the boom-less rig the sail area is reduced in the same way as a furling jib.
It is a Swedish invention from 1933 by Fredrik Ljungström. You can still see some of the old boats around here in Sweden.
It works, but there is some problems with it. The sail is triangular, therefore the mast must be tall to give sufficient sail area and there is no boom to facilitate downwind sailing. The sheeting point is too low.
I got around these points in the following ways.
To increase the sail area I used a vertical club as the Chesapeake Bay racing log canoes. The vertical clubs I can make of composite to minimize their turbulence and make them light.
To overcome the problem with the sheeting point I will rake the mast aft 20 -25 degrees or so. That way I can sheet my two mainsails like foresails.

The rake also moves the center of effort aft. I like that because my side by side masts are forward of the fore bulkhead to not be in my bed and I like to have more weather helm. Rake is good for offshore work, as it gives a lifting force and keeps the boom from dipping in the water and possibly breaking when the boat rolls deeply.
This rig creates less forces on the masts as the lugsail hangs on the top of the mast therefore I can make it longer and more tapered.
The Ljungström mast can be rotated to get the sail always on the lee side. This will make the suction side more smooth reduce turbulence.

The chances of my succeeding in doubling Cape Horn is uncertain as I will have strong prevailing winds and currents against me, but that makes the undertaking interesting. Even if I do not succeed all is not lost as I can do as Captain Bligh did.

He had for a month unsuccessfully tried round Cape Horn in Bounty but was finally defeated by the stormy weather and opposite winds and forced to head east repair damage in Cape Town and then take the longer way to the pacific by sailing east by way of Australia.
If the canoe yawl Exlex proves to be fast and able, only then will I try the Cape Horn alternative. My hope is that she be a good boat.

Below photos

The note on my door
The new model to the left compared with the balanced lug sail rig
The new rig running with wind behind. Whisker poles will be needed but they are short and light maybe 2.5 meters at the most.

In conclusoin: I will try a new rig, more easy to reef, I will try Cape Horn. If I reach the Pacific via Cape Horn NZ will have to wait.

OUTSIDE LAMINATED

With the help of 4 friends. Today 2 of October 2021 the outside of Exlex the canoe yawl have been laminated. Things went well. We started with the workshop having high temperature. Primed the Divinycell. Turned off the heat opened the door to let in cooler air. The air in the cells shrunk and sucked in epoxy.

Then came on all the layers. We started 10 am and were done 4 pm had had a break with something to eat before we put on the peelply.

All of us were happy with the job thinking this is the best boat we have done.

We expect great voyages from her.

I be happy if you support my project

Below is two video of the doing and the result. The doing video is credit to Petter Robért

PROGRES ON HULL MADE

Now all the big pieces to the hull that needs bending are in place and I have started to longboarding and shape the the hull.

Most of the wedges still have to be glued and that is going to take a long time but it is routine job and lets me think of other things when dping them.

A video shows the hull.

More videos is planned for my youtube channel Sven Yrvind. A good thing is to subscribe to not miss things. Support in the form of donations is welcome.

WHY SHE SHRUNK

The boat is now planned to be 6.4 meter instead of 7.8 meter.

Reason is: 2020 I sailed from Ålesund Norway to the Azores 78 from there to Porto Santo Madeira 23. Problem was on fora on internet people did not like the 1.7 knot average speed. They thought I sailed to slow. Me myself I was quite happy taking it easy. There is no engine on Exlex. Nowadays to wait for wind is not common. In fact when I was becalmed north of the Faroe Island for a few days. One day I heard a deafeaning sound that broke the silence. It was a rescue helikopter abouve my head. Somehow with the modern notion of thumbs up I convinced them that all was OK and they flew back to base.

Back in Sweden I started a 7.8 meter prototype longer for more speed. This year I sailed Madeira – Acores in 21 days and then to Ireland in 28 days.

When I came back to workshop and saw the long boat I got second thoughts about all that speed and how much less handy the boat would become. I do not sail for a destination. I sail to be out on the deep blue endless eternal sea. Sailing slowly is like a slow walk in the woods. It suits me. The sea is kind to the gentle seafarer.

I scrapped the long boat I started a new shorter one, not a prototype but a composite sandwich construction that I hope will take me on many a long sail in the less crowded high latitudes.

Below a recent video, below that a video made by an Amarican about my life.

SCARFING 70 mm DIVINYCELL

Hi Friends.

Yesterday I recieved the Divinycell for the hull. Its is 70 mm H 80.

Today with the help of Peter and a ratching strap as clamp we scarfed 3 sheets.

Picture below

We also made a video for my Youtube channel. I suggest that you subscribe as more and more uppdates on the building of Exlex the Canoe Yawl 6.4 meter long 1.4 meter beam will be on video.

THE MOLDS SEAMS TO BE FAIR

Hi friends.

Now all the molds are up and the stem and stern.

The new Exlex the canoe yawl will come out I think 6.4 meter long and 1.4 meter beam depending on the thickness of the Divinycell.

To my eye she looks sweet. Her hull remains me about Bris a boat I cruised many days in 1972 to 1976 and later 1982 and 1983. Bris was 6 meter long 1.72 beam. Also a double ender. I built her in my mother basement.

Exlex is 4.57 beam long, Bris was 3.49 beams long. Exlex is more slender, she is also a bit smaller 6X1.72 is 10.32 veras 6.4X1.4 is 8.96. Lenght is not a good measure of  size in boats.

Below are a few pictures of Bris.

!972 I started from Göteborg sailed to Holland. Trailed her back to Sweden to fix things. Spring 1973 left Sweden to Norway north of Scotland to Madeira down to Rio Argentina tried to round Cape Horn she was capsized and pitchpoled sailed east to Tristan da Cuhna styed there for 4 months then St Helena Martinique Newport Marthas Vineyard Acores Sweden
Bris being built in my mothers basement. Start midsummers eve 1971.
1975-1976 worked with Dick Newick on trimarans on Marthas Vineyard. A toster and 110 volt kept me warm during winter
1983 becalmed in ghe Saragasso sea on my way to the Museum of Yachting I did see all the Am Cup races when US lost the Cup to Australia
I clamped a spline a batten to the molds to sea if the were fair. It was very good. I like the shape. In my oppinion she will be a happy boat. I got that feeling.

BACK IN WORKSHOP AUG 2021

Hi everyone.

Friday 13 of August I landed in Copenhagen. Peter and his wife was kindly there and picked me up. 23:30 the same evening I unlocked the door to my apartment. Everything was fine. I did 3 push up to get in shape. I had not done any physical since leaving the flat in late spring.

Next morning I pumped my bycycle and pedaled to my workshop. Everything was fine.

Before leaving I had made a model of the hard chine hull I converted her to soft chine. Next day proud of my country I pinted her blue and yellow.

Me with the model 1/10 of 7.80 meter long. I have shorted the real boat to 6.4 meter long.

During my sail in Exlex 2020 and 2021 some of the following thinking have been done. As follows.

After 149 days, nearly five months at sea in Exlex back on land I have decided to go ahead and build Exlex the Canoe Yawl a double ender 6.4 meter long with a beam of 1.28 meter in composite sandwich construction. Starting as soon as I can get the building materials.

Exlex was 5.8 meter long with a beam of 1.23 meter. She had a blunt scow bow and a transom. Long time in her and other small boats have made me realize that I am happy in a small boat.

Exlex had many good properties and a few not so desirable. Some of the properties that will be ameliorated are as follows:

Hull shape, the new boat will be double ender with soft chines. That will reduce resistance and enable me to take storms with her stern facing the wind riding to a sea or para anchor or Jordan series drouge through a stern tube.

She will get much more weather helm. The centerboard and rudder will be moved forward and sail area back in form of a mizzen mast will be added.

The living area, bed and seat will be enclosed by two waterproof bulkheads. On Exlex only the bed was so enclosed and the doors was only splash proof.

The rudder axis will come up foreword of the mizzen mast in a tube making it waterproof. This will bring the steering lines inside easier and make the rudder complex design simpler. The steering lines arrangement will be above the bed and athwartship. There they will not interfere with the drawing board and will be easy acceseble. The jammers will be of good quality.

There will be a deckhouse with a 360° view.

There will be a rudder indicator.

There will be side by side masts, a biplane rig as on the 2018 Exlex. I give her 8 square meter sail area. That is twice as much as on the previous boat. Downwind, the side by side arrangement of the masts ensures that the sails will not blanket each other. That arrangement worked at sea but gave problems in port. That problem is now solved.

The hatches had several issues. Those are easily corrected.

The stowage will be improved. Food will now be in a more protected part of the boat.

There will be some deck space that can be used for seating and standing.

The Canoe Yawl will be 0.6 meter longer than Exlex. Length is however not a good measure of a boats size. Weight is better and she is planned to be a bit lighter than her predecessor about one ton in cruising trim for 60 days or about 5000 miles autonomy average.

It is not easy to visualize what I mean by all this, but gentle reader be patient and bit by bit I will post by post describe them more clearly.
I also now have a youtube channel Sven Yrvind and I suggest that you subscribe to that that you do not miss videos.
Also I thank everyone that has donated to my project. There is a donation Button on this Webb site.

Some photos. Click once or twice to enlarge.

Exlex track 2020 and 2021 total time 149 days
My plan is to make her 6.4 meter long and 1.3 meter beam but during building things happens so we will how she comes out.
The side by side rig on Exlex 2018 version. Worked very well at sea but was a problem in port as the mast was outside the boat. Not good coming alongside anything. That problem is now solved.
Most of the molds are now up an extra chine have been added.
From the stem. The hull is symmetrical but I have chosen to put the centerbord towards the camera and the rudder att the other end for no practical reason.
