For same time I have been working with handholds and steps on the outside to easier get back on board after a swim. That job is now done so today after the run and exercise I started on something new, to modify the rigging.

Unfortunately there is interference between the centerboard and the new sail. This I knew. The centerboard I was not able to mowe and there was no other place for the mast. So I did not have a choice. In Next Design the problem is solved. It is not so difficult to make a centerboard or a mast or the other hundreds of pieces needed for a cruising boat. The biggest problem is to make a design where they do not interfere with each other. After I have made a landfall in Australia hopefully there will be new interest in my talks and my books and my economy will hopefully get back on an even keel and also hopefully I can get other persons to get interested in this wonderfull kind of low energy boats that I am designing, because they are so much safer and simpler and more economical than what is used nowadays. Today I use the same size of boats that I used 50 years ago. At that time, in the sixties that size of boats where common, now they are a curiosity and yet they work as fine today as in those days.  More and more people today do consider mans effect on the enviroment and they realise that in that respect an oar is better than an engine, also it is quiter, cheaper and takes up less space. Also it keeps its owner in good health. Cruising boats do not have to be 10 or 20 tons heavy 40 – 50 feet long. Cruising should be a hobby not a way to show conspicius consumption. Its OK if some boats are 40-50 feet long, but smaller boats should also have a place on the wide oceans. That is my idea.

If I can get 10 person interested in Next Design the tooling will be spread out on ten person and that will reduce cost.

Provisional the centerboard can not be fully raised. 15 cm or 6 inches will be below Exlex bottom when the new sail is used in full. If I take a reef in the sail then I can rise the centerboard fully.

In Next Design the interference  problem is solwed.

Below are 3 pictures.

The problem with interference is solwed by lower the centerboard 15 cm or 6 inches
The centerboard has to be 15 cm or 6 inches below the hull as not to interfear with the sail. There is no problem when the sail is reefed. I can live with that.

During test sailing the AIS-reception and transmission was not good. Reason antenna was low down I guess.

Also Exlex proved to be very stiff. I decided to add a mast. One more mast will increase sail area by 50 %, from 4 square meters to 6.

The new mast will be a glass one. Glass masts are heavier than carbon ones but the AIS-antenna can be placed high up inside her. A third advantage is that by placing the third mast well forward it will aid Exlex running downwind. Exlex masts are self-standing having no shrouds. I can thus let out the sails more than 90 degrees with no chafe. Should Exlex head up into the wind the windward sail get more pressure and the lee one less thus making the system stable and self correcting. Exlex is a simple boat with no selfstearing gear. To make her keep her coarse I find a equilibrium between forces acting on her.

Usually a glass mast is more than twice as heavy as a carbon one. The glass one that I made came out at 2.8 kilos. The Europe Dingy masts are 2.5 kilos each for the same lenght. The reason that the different masts are nearly equally heavy is that, Europe Dinghy’s mast are restricted by racing boat rules. Their mast are forbidden to be as light as they can be built. The boats started out with wooden masts, then, came aluminum, then carbon. To be fair to the wooden mast owner’s carbon masts are ballasted with glass. Very democratic, but its one more example on how racing rules makes bad boats. Racing boats are not fast but fair. Cruising sailors that not compete should avoid boats influenced by racing boats. Unfortunately that is not possible unless you build your own.

Exlex mast holder will be attached to the strong center board case. To be able to fit the mast holder vertical I have placed a square piece of wood in her to have some thing to measure against. I did not have a pipe that fitted.

Doing a calculation using Pythagoras theorem. I found a neat formula that helped me to find the side of the wood, just divide the pipes inside diameter by the square root of 2.

Below are some photos.

The square stick in the foremost mastholder. The new mastholder will be next to the yellow centerboard just behind the hatch.
The formula I derived to calculate the side of the square stick. Just divide the diameter by the square root of 2 or 1.414
The modell the two forward masts. Here the sails are let out more than 90° making, hopefully Exlex sail stable downwind.

Monday 2 of September 2019 Captain Thomas Grahn towed Exlex from Hunnebostrand on the west coast of Sweden to Västervik on the Swedish east coast behind his wife’s father’s car. Everything went fine. It took us five or six hours. It was a shortcut. Sailing from Hunnebostrand to Västervik is about 500 nautical miles; it would have taken many weeks.

To be able to trail Exlex is a one of her many desirable qualities. Last year we trailed the first Exlex 5.76 meters to Dingle in Ireland and then I sailed her to Madeira, 2011 I trailed the yellow boat 4.8 meters long to Ireland and then sailed her to Martinique, 1988 I trailed Amfibie-Bris 4.8 meters long to France and then sailed her to Newfoundland. I have trailed many of my small ocean going boats to various places. I suggest the idea. It adds a dimension of freedom, so why not?

Exlex, although small attracted much attention in Hunnebostrand. I had to answer many a question like if she was able to sail to windward, if I was steering with the sculling oar, what would happen is she capsized and more. I assured every one that she was a very able boat. I sold many brochure’s and some kind persons donated and some invited me to eat ice-creams.

I made a long list of possible improvement’s to carry out before the month of May 2020 when I plan to depart.

I am very pleased with the performance of Exlex. She pointed high and sailed fast. If I watch my steps the upcoming voyage will go fine

Docking Exlex
Each evening the speeker on the sightseeing boat was telling everyone everything about Exlex
Onlookers were querius about my boat. Why people have so huge boats nowadays no one reflected over


Kind persons gave me icecream

Something gone wrong with my computer I am unable to show more pictures. Hopefully friends will fix it.

After speaking to several friends I can now continue . Here are two more photos of Exlex being rolled over.  This time it was not for stability but to test for leaks.  There were still a leak on rolling to starboard in the ventilation system, a small one screew hole. I had plugged 2 screew holes before. Rolling to port she was tight, no leaks. The hatches were also waterproof. The one leak I think is easy to fix, but Murphy is sitting on my sholder trying to to keep me alert.

Rolling to port. No leaks. People on the bridge are curous wondering at the strange Exlex
Now the hatches are under water. No leaks. The bronze plate can be seen in the middle in the front of it is the centerboard slot.

Work is now being done on Exlex.

Good news to all lug nuts. Again I have I been out again testing Exlex, now in stronger winds guessing upper force 4 or lower force 5

She now pointed about 53 degrees from the the wind compered to 65 degrees in less strong winds. Well a friend told me that his double ender pointed 45 degrees from the wind so I made an extra effort to steer well.

Below a photo of my Ipad showing the track.

Production boats try to copy racing boats windward performance. Racing boats are optimized for going to windward. Cruising boats sail passages downwind. A boat optimized for windward performance is not at its best downwind. For example deep ballast keels and weather helm is not a good thing downwind.

Exlex is optimized for downwind sailing. She has lee helm with her daggerboard up no ballast keel and balanced lug sails. I am often asked if she can go to windward. She do so very well although she will not win any races but she I hope does better than a production boat downwind with her lenght/displacement ratio of 150 and small wetted surface and square sails that outperform triangular Bermudan downwind.

Below is her track of todays sailing outside Hunnebostrand. It is 50 degrees between them and if my calculations are OK she sailed 65° close to the wind.

Sailing in Hunnebostrand west coast of Sweden in light winds

I am staying in Hunnebostrand with friends testing Exlex.

The natives are friendly.

Imam getting more and more used to handle her and the procedure to set and fold sails are getting quicker and quicker. To live in Exlex is very comfortable as there is plenty of space. She is very roomy. Exlex treats me very well and I am happy in her. I may stay a few weeks more here before bringing her back to my workshop on the east coast to do a list of modifications during winter. I May I intend to trail her to Dingle western Ireland then 1200 miles 25 days to Madeira then 5500 miles to Mar del Plata in Argentina 95 days, the 8000 miles to Albany Australia 150 days assuming 2,5 knots or 60 miles a day average. This is the plan a start. Reality may be very different. We will find out.

I have been out in Exlex more times. With crews. Problem is my eyes are now not the best or do they make the print in the charts smaller nowadays.Its a lot of rocks here and I have a daggerboard not a pivoting centerboard. I do not like to damage its so I am prudent.

Below two videos from today 19 August 2019.

Its friends that have helped me to put up this on youtube.  Its kind of to modern with music and stuff to my mind it is confusing but it has to do bucause the purpose is to show Exlex sailing so it has to do.

I will stay here in Hunnebo a bit longer. The natives are kind.

Exlex is now on a new dock in Hunnebo. In the previus location I violated a rule saying I could not stay on a friends place while he was out in his boat.

Here is plenty fine so I am happy.

Exlex Visit Hunnebo Its the yellow boat to the right in the picture just below the red houses

I am now in Hunnebostrand. I hope to do some test sail.

Here is  a picture

Exlex is the yellow boat to the left in the picture

I have problems with the computer and its late so I have to come back later after asking a young person how to do

Doing a few odd jobs.

Saterday I think it was. Håkan and me was out sailing. The wind was Beufort 3 maybee. The picture shows my AIS speed on Marine Traffic, 2.6 average 4.3 maximum. If Exlex can average 2.5 knots I be happy so this is a happy start
Here I am making a mosquito net. A light chain is sewn on to hold it down inside the hatch coaming.
Exlex sculling oar has excellent bollard power but when the boat is making speed through the water it kind of floats up. Only rapid mowement helps. I am a spokesman for slow sculling strokes so I am making a new oar. The picture shows me using my table saw. I have clamped on the shaft to a rolling table to keep the same angle when sawing the slot. The laminating blade is standing on the table. This is slow work because first I have to wait for the glue to set on the blade then next day I glue the blade to the shaft, the next day I reinforce one side of the oar with carbon next day the other side, next day I glue a stainless steel tube around the shaft to prevent wear, but I am getting there.
A friend told me that someone has said that I should have done the roll-over test with masts. It was not practical because the water was to shallow. However I do not worry becouse as you can see the mast floats, they have lots of positive boyancy. With masts standing Exlex will have even more rigthning power. True the sails will damp the motion but that only makes the person inside more comfortable. The rightning moment even without masts is very strong when the boat is upside down all the way to 180° of heel. And yes my visitors is my friends Lena and Beppe 

Soon the sculling oar is done and more sails will be done.

The plan is to trail Exlex to the West Coast for more sailing. The future looks bright.
