Hi Bernd

Some development work also on the Duo 900 Italy

Hulls in place, the pipes have been painted and do the last of the paint on the hulls.

In the meantime I am working on the 10,80m long wing mast.

Yes Bernd full body is the only structure that convinces me and the shape will be very nice.

It will be a Duo 900 Aggressive and bad your design masks this and I had no doubts. I like it as it is!

Hi Bernd

For lamination of the wing mast I will make a 600gr unidirectional fiberglass layer and a quadaxial 820 gr fiberglass layer. Without lamination it came very stiff and solid and the weight is 42 kg, the two spreaders in the center and the lamination are missing and I think I am under 60 kg. I preferred to have a strong structure and not just think about weight as many do. My thoughts.

The boat has been painted white the upper part and the silver hulls. Now at home in the cool :-)) I prepare the net for the trampoline.

I'm not working right now, temperatures here in southern Italy are not 40 degrees but around 32/35 degrees. We can't work for the moment.

In September we will start again, I will dedicate 10 days of work to finish the Duo and then I will resume the KD122 for the final phase.

Hello happy holidays everyone I need it ...

Sounds okay to me. I understand your thinking. I have noticed the wood slats you used to "close" the mast structure.

It is on the heavy side. You will see how it will work on the boat. The rotational force will be relatively high.

Nothing to worry about with the beam of the DUO 900. Only be aware when a gust hits the boat. The boat will accelerate and want to point windward.

To avoid the related rotational force, you have to bear away and slacking the boom.
