Most builders use NACA sections for keels.
Not me.
Bescause NACA sections are made for airplanes and the NACA sections have infinite aspect ratio far from my bilge keels that have a cord of 1.5 meter and a lenght of 0.25 meter that is an aspect ratio of 0....
After much hesitaion and apprehension I now go for vertiacal battens, two in each sail.
This allows me to reduce the height of the mast to 2.2 meter freestanding.
The sail area is 3.24 square meter.
Small things attract small forces. The battens therfore w...
It takes six cut outs of 4 cm to build up 24 cm pattern. They are all of different lengt as the leading edge slopes 45°
But by dividing the template into fractions and moving it bit by bit I can use the template for all the six pices even as they are of d...
The six 4 cm Divinycell pieces are now glued together with NM-epoxy.
Time for shaping. This is dine by eye and a good thing is if the keels can be symmetrical that the boat do not sail in a circel.
To make work more easy I made a holder for the pattern. No...
Today I did a bit of fairing on the keel pattern.
I used a new product from the auto industi. It cures in only 15 minutes. I am used to 24 hours curing time. The time to my disposal including cleaning the tools.
It was a start. I do more tomorrow.
I am tir...
Diab makes grid scored Divinycell. It is Divinycell sheets cut into tiny squares glued toa matt. They can thuse bend into 3-dimensions. If you lay them on the hull and apply epoxy that will freese them into position. That done you have the shape of the hul...
Now the keel pattern is on the flange. When done I noticed that the keel is not excactly straight. I have to live with that. Comforting myself that boats do not sail stright and that I am human.
Anyway tomorrow I can take the mould of the hull and turn the...
I did put the keel in the middle when adding the flange. The reason was to get one pattern for port and starboard. The middle of the boat would be a compromise. That way I will only have to adopt a little to each side to make a good fit to the hull.
I had ...
Peter is back. Here he is helping me to demonstrate how strong my darling was.
Was because she is no more.
I have decided that the bulkhead hatches take up to much space.
A video from 22 January show me getting into the fore compartment with a Center board...
I have been experimenting for maybee 3 months or so.
During that time much wothwhile development have been done.
The modified Ljungström rig and the twin keels will be great improvements.
The Ljungström rig promis to make the boat more weatherly.
The twi...
This is not very exciting just taping fillets in the dining room, but it makes progress and makes the boat stronger.
Things are going well.
Before the plan was to have water in the dining room below the seat. Now water is mowed to under the bed.
That way I...
Today Göran Marström did visit my workshop.
I asked him many questions about my planned rigging and upcoming voyage.
I got the impression that he did not disapprove.
Things are moving along.

I am working on the storage in the dining room. They are in two etage. An upper with sliding locker and a lower with lids from the side. The space is also divided into smaller parts.
There is also rumors of gigantic project. A navigational tunnel below the...
The work in the dining room continues.
Today a shelf have been added.
But mostly I have been busy with a new 1:20 model.
The old one have had to many changes. It have been the centerboard, the rigging have been moved several times and twin keels added.
As ...
Work proseeds nice and slowly.
Today I have added started on a subdivision on the shelf. It is important to keep things restricted on a boat that is mowing. To keep the lockers small is a GOOD IDEA.
Also a bot more on the model, now the beginning of the de...
Today an other worthwhile drive. Håkan lent me his van and with the old bronze keels to be recycled and the pattern I have driven to Lammhults Gjuteri in Lammhult not far from Växsjö Småland.
I was shown around seeing a lot of patterns. Most of the pro...
Curius about my new destination, Isla Chiloe I ordered a chart from my The Admiralty catalog that I got for the millenium 2000. Seams that time has passed and changed have been made in the elapsed time.
The chart number was OK but it was from a place in In...
One thing leads to an other and often the cause is not obvius. Here the Putins war lead the idea of visiting Falkland Island and Isla Chiloe.
Falkland and Chiloe lead to twin keels.
Twin keels lead to the decision to go skip the modified Ljundström rig a...
Some people say that it is complicated to tilt a mast.
I say thats not so if the mast is small on a small boat and if it done in simple way.
A freestanding mast stands in a prismatic socket. However if one end of the socket is larger than the other the mas...
Yesterday some people suggested that I should use wedges for the tilting mast. That would keep it in the desired position sequerely. The new problems arose. How to unwedge the mast.
That is certainly possible but most likely a tool is needed at least occas...
Here is more work on the lockers in the diniong room. I am trying to get it good. I started with the port side. If it works I do the same on the starboard side. Work brings surprises every day.
That makes it eventful. I do not need other entertainment. In ...
HI friends.
Today I have been tacking up panels as subdivisions and part of the food box I will sit on in the dining room.
Time is mostly spent on deciding where to cut and where to place the parts.
As time passes there will be less and lesss choises, easi...
The accomondation consists of a lot of small pieces panels subdivitions and so on to keep track of things and to keep things in place out on thebig waves.
Little by little progress is made. The difficult things is to arrange so that the boat functions and ...
The hole for the rods to the vertical hatch covers is now done.
Here is a test with a wooden rod.
I might use metal pipes, 8 mm diameter. I have copper. I might even get stainless steel.
Piece by piece the accommodation is getting in place. This is a job t...
Not much done today, but got an idea how to proceed.
Did some gluing up for tomorrow. I am working on the central storage below the seat in the dining room.
I have also got an idea how to do the reefing in a simple way.
On Exlex 2018 and Exlex 2020 I messe...
Now the dimensions of the seat is determined. It feels fine. It is going to be a pleasure to sail a boat with such a nice seat wathching all around everything that can bee seen through the windows.
The boom is just experimental. It is a wooden one and is n...
Peter is not here. But try to imagine this rope representing the bottom of a 2X2 meter square sail.
In the fromt eyelet I put a loop with a loop. I peg it on a peg. That way the bottom fromt of the sail is attached.
In the back I use a line as an outhaul....
HI friends.
Today I have done different things.
During my evening walk I realised that to get most force from the reefing line to the sail the lines must be parralell. Easy to understand if you are familiar with vectors. Vectors is a concept useful to sail...
Today I have been working with the dining room, to secure the hatch lid for the stovage below the seat.
I have fastened two long bronze nuts. Screws into them will hold the lid. The are fixed with screws and NM-epoxy and glassfibre.
To prevent epoxy from e...
Mainly today I have worked on preparing for the two screws that is going to hold the hatch in the dining room.
One screw would have been plenty but I like to have redundancy so two screws there will be.
First I put the long bronze nuts in place. Then I scr...
The two screws for the hatch are now fitted. There is mostly some filing to do as I can newer get it precise from start. But good enough.
Also a few more subdivisions are made on the side compartment below the sliding hatches.
I am also preparing for the t...
Originally the plan was to sail to NZ eastabout south of Africa and Australia. however after much thinking a new plan Falkland Islands Cape Horn and a landfall in southern Chile was decided on.
The ordered sea chart for the possible places in Chile have ar...

After a long time I have now reached 83 years of age. Many things have happend during thosen many years. Here is an appeal. I ask for donanations that I may continue the building of Exlex.

This is the method I use to transfer water from jerrycan to bottle.
I will have 12 or maybe 18 green nomally 5 lite jerrycans. The same type NM-epoxy use for the resin. The are of good quality approved for dangerous goods.
To transfereing the water without...
111 liter water is more than I need. But thats OK. It is redundancy. I the unlikely event af a mishap.
From the start the Idea was that the side panels in the sleeping room should be parallel. 80 cm vide at head, 80 cm vide at feet.
But now with the chang...
