Today a big change.
I have killed my darling.
The mizzen is gone.
Exlex will not be a canoe yawl.
Exlex the sailing canoe is her new name.
Why?
I did some estimates on lead in this case I use the word in a geometrical sense. That is how far the center of e...
Today I bought a 5o mm steel pipe as a mock up for the rudder axis. For a long time I have beeb uneasy about the results.
It was a relief that it turned out so well.
With the aft end of the boat resting on the rudder axis the draft was only 45 cm or 1foot ...
There was a question about why I chose to make a double ender.
Nowadays close to every production and amateur boats are not double enders.
If so many do not choses double ender is there something wrong with them.
They have disadvantages but it is more buro...

The abouve link is to a video I made in Horta harbor Fayal Azores sommer 2021.
It is also about the idea of achoring from the stern
At about 1 min 20 sekund you can see a boat sneaking about. The boats ...
To summarize the betterments in the new boat Exlex the sailing canoe so far here is a list of 15 items that will enhance performance and practipality.
I will put the text on my website Yrvind.com so that you by reading hopefully will understand it well.
On...
A boat with a canoe stern have less space aft and if the boat is decked and the steering is belov deck the tiller cannot swing outwards.
However quadrants are interesting the cables come of as tangents from the center line. This means that there are more s...
I have been lucky with Elisolation in Laxå.
The G 11 pipes for the hawse pipe came very quickly and they are superstrong.
I persuaded one of the persons in the building, a big guy 110 kilos to hang out on a lever very much longer than the rudder axis on a...
I had a very interesting day and night.
Once I started to think of the different configurations of blocks quadrants and drum steering wheels new possibilities turned out.
Now after the days work I kind of got a Darling I call her the Butterfly quadrant.
Of...
This is a mock up video of the placement of the mock up drum winch for the hawse pipe tail.
It needs improvement. I got an idea but I realise that it is best to make a functional drum winch with the right dimensions.
I was sitting in a good position but th...
The wheel in the cockpit was not comfortabel to use when standing in the cockpit hatch.
Here is a way a yoke tiller with steering lines. I have succesfully used steering lines 1989 2007 2011 2018 2020 2021. It will work well as a compliment and it is a si...
Today the epoxy on the functional mock up of the drum winch had cured. I shaped it and screwed the pieces together.
I tried several positions. Unfortunatially it took up to much space.
Hindsight is 20 20.
I only needed 50 - 60 cm more 2 feet. If I had sque...
i now got a good idea of how to deal with the long rope and chain for the hawse tail and how to get space in the cockpit.
I will not use a drum winch as was the first plan. There was not space for it and to put it on the deck is not good seamanship. There ...
Figure 8 flaking is a good way to avoid entanglement of the chain rope anchor rode.
I built a device with two pegs on Bris in Marthas Vineyard 1976. It worked well so now with no drum winch I will use that Idea again.
Two pegs will keep the rode in place a...
Amfibie Bris was the first cruiser using the rudder as lateral area. Earlier I had built an open boat to test the idea and it had worked very well.
Later several people built boats using the same principle from drawing I made in collobaration with Rolf Eli...
NOW I ADD TWIN KEELS TO RUGGEDIZE EXLEX
Twin keels have been on my mind for a long time in fact since 1980 when I was up in Maine and John Letcher help me to draw a nice twin keeler. I worker on her for three years but things interfered and she never got f...
The Ljungström rig invented in Sweden by Fredrick Ljungström in 1933 have some very desiriable properties.
Foremost is the ease to reef. The freestanding mast is just made to rotate to pull on a rope, like a furling jib.
This rotation also makes it possi...
Doing some volyme calculations on the bilge keels I realised that there can be a lot of low weight in them.
That will increase stabilite a lot.
I also realised that with bilge keels the mowing ballast was now less important.
To keep things simple I am elim...
Weather helm is important when sailing into the wind. But most cruisers avoid sailing to windward.
When sailing downwind weather helm is a pain.
By with my bow centerboard rised I get lee helm and a boat that is stable sailing downwind.
The use of my bilge...
This Andersen 28 self tailing winch shall give 28 thimes the force. I do not know how much force I still got in my arm 20 maybe 30 kilos. That times 28 is something like 700 kilos. With the longer lever 800 - 900 kilos.
Using a block 1700 kilos.
Then in th...
Across the street, I am lucky, Grönitz do buiseness in steel. Today I found duplex stainless steel. I was looking for something else a weight that drags the chain through the PVC lined hawse pipe but luck favors the prepared mind.
Below is somthing about...
The change of route from NZ to Chile and cruising northern Patagonia reducing needed food from 180 to 100 days and making bilge keels neccecites and permittes many changes.
Now I need only 100 hundred liter water. My green plastic can holds 5.5 liters. 6 w...
To design and build an ocean going boat is a complex problem. By dividing the problem into smaller and smaller parts it becomes simpler and simpler until in it is straight forword.
A curved line is more complicated than a stright line. But every time you s...
The change of route from NZ to doubling Cape Horn have left much hidden residue.
I have to be eagle eyedness is needed to detect it.
Luckily last night I got the idea to move the water under the seat. I was lucky that previus to that I had narroved the bed...
Doubling the Horn
Provisional itinerary
Doubling the Horn entails sailing nonstop from a point above the 50th parallel in the Atlantic, down around the Horn and back to a point above the 50th parallel in the Pacific. Only this near 1,000-mile passage i...
Ekonomy gives more problems than all storms together.
Now thanks to the landlords of my workshop the rent for two and a half year is payed.
If I have no money for the boatbuilding there is always something on the boat I can improve that do not need money.
...
To make a perfect fit I will inject NM-epoxy between the fillets as done before.
Now the groove is much longer so I am getting nervous that the epoxy will cure before it reached all the way.
Now with the NM-injectrion epoxy it will be better. Its curing ti...
I go for broke becouse only the best is good enough for my boat. Bronze keels are antifouling because they are 90 % cupper. Bronze is expensive but it is also strong and resiliant. It feels good to know that will Exlex be bumping on the ground with a ebbin...
2015 about that time I realised that I could not be happy with Yrvind Ten so after about three years I scrapped her.
The bronze bilge keels I saved for a time they might come in handy.
Now is that time but they will be cast into a different shape and more ...
After two days of brutal work the old bilge keels are now ready to be reeshaped. Mikael at Lammhults Gjuteri is going to calculate the weights if keels with different wall thicknesses.
The front and bottom are going to be thicker for strenght.
I aim at 12...
The bilge keels gets quite a lot of surface. They will I think be big enough to create enough lateral resistance. According to the book, 3.5 percent of the sail area is normal. With my bilge keels I can get twice that area.
The problem is to create lee hel...
I have started to plug the hole I made for the centerboard. I started to fill the hole with Divinycell. Next I grind it smoth and even then I laminate on top.
That done, next step is to turn the boat upside down. To smoth the outside and laminate it.
There...
Today I have been making the centerboard plug made of Divinycell smoth and laminated it with carbon fibre. A simple step.
Also I have been thinking about the mizzen mast.
I am quite pleased with the idea of the modified Ljungström rig. I am considering it...
Now I have turned Exlex upside down to plug the hole where the centerboard should have been.
Also to design and make patterns for the bilge keels.
I started to build Bris 1971 and sailed her in the North Atlantic and South Atlantic, that is by definition ...
One thing leads to an other.The gone centerboard replaced by bilge keels needed a mizzen to give her weather helm when so desired.
The problem back there with the double ender was sheeting. At first I was back to the balanced lug sail for the mizzen.
The b...
A bit more work on the rigging on the model then I will start to do the patterns for the bilge keels.
Many things have to be considered. Like their position in relation to the sails. As it is free standing masts they have to be near the bulkheads.
I like ...
Something AWESOME is coming!
