Jakob Alander has kindly helped me to plot the stability numbers below making it much more understandable. As can be seen there is no need to have a deep keel to get positive stability through 360 degres. Matt Laydens Paradox and other small boats with similar height to beam ratio and a low enough center of gravity confirm this.

Here are some stability calculations and other numbers who Guy Lilljegren kindly has provided me with. There are three sets for center of gravity for 5, 10 and 15 centimeters above the waterline. Hopefully the center of gravity will come out at 10 centimeters above the waterline, but only the Gods know for shore. The numbers are really too small to reed but if you click on the pictures, first one time, them again, they get bigger and bigger.

I have been very fortunate in that Quantum Sails Loft in KungÀlv have undertaken to sponsor me with sails. From previous experience I know that the do an excellent job. Below is Patric sewing on a sail to Yrvindaren. (see photos)

Here Henrik is showing all 0.5 sq meter of it.

Quantum sails will sponsor an illustrated lecture in Göteborg on next Wednesday the 29 October 6 30 pm. If you are interested in hearing me talk about my voyages take contact with quantum sails phone 0303 10818 The talk will be in Swedish.

Below is the finished aft deck waiting for the deck house, the pair of compasses indicates the angle of its back. For the first time I have been walking around on my deck. It feels great, there is ample room.

The last work on the interior is now done, it was getting some NM-epoxy on the underside of the shelves. To make the epoxy flow in the right direction I turned the boat upside down and on its sides.

I also weighed her. She was at 250 kilos or 550 pounds found lean and strong.

After that I started on the lower aft deck. Here I am fitting the frames to the deck curvature which is 85 millimeter high on 1320 mm beam.

Here looking aft, having removed the pattern.

The frames are ready to take the Divinycell which for the deck and deck house I use a thickness of 30 mm and a density of 80 kilo per cubic meter.

After laminating the inside with one layer of 600 gram quadruple glass in NM-epoxy I bend with the help of lead weights the panel over the frames.

To be continued…

KÄre Ljung an areodynamiker one of Ridders disciples, now working at Marströms, has helped me to modify a NACA-profile to suit my demands.

Here Gösta Larsson who kindly has offered to help me mill the rudder and CB Divinycell-core is programming his NC-machine to do the job.

Here Gösta is adjusting the machine.

Here he is advising me how to watch the machine mill the divinycell to size. The tolerance of the machine is better than a hundred of a millimeter. Fare more precise than what I need.

Here Im watching the machine doing the precision work. Thank you Gösta and your company Larsons mekaniska i Hjorted.

In the meantime Börje from BT-Hantverk has done the rudderfitting. Shown below.

Here I am doing a bit of mockup with the stearing lines I use instead of a tiller, saving a bit of place on my small aft deck. Tacking care that I get a god angle of the lines also when the boat is going backwords and there is a reverse pressure on the rudder.

Sad comment. Even in our little quite town of VĂ€stervik there is vandals, bored people. Here someone has destroyed our nice little clock in the park outside by throwing a stone at it.
One of the good things with siglehanded ocean sailing is that you are fare away from the vandals. Life on the ocean wave is freindly.
