    No other than just some more in-harbour tests, I had to reposition my solarpanel and the way it is adjusted, and so many more small details. Next week first sailing!

    Today I finished 2 windvanes: one foam-cored Carbon of 60cm and one polycarbonate of 70cm. Surprisingly the carbon weighs 275 and the PA 325grms. Finished in fluo paint and decorated with glow in the dark strips: i also finished the trimtab: foam cored with carbon, now in anti fouling and to be polished: Now that I have almost finished all components and I can calculate the finished weight: this will be below 2000gr, some 500gr less than the “design brief”

    All Made exclusively on iPad, with Shapr3D: https://shapr3d.com/ i never learned anything about 3d design software, but, with quite a lot of time, trial and error, that Shapr3D allows me to make these designs now.

    This is the design for the small 6cm radius quadrant to be mounted on the rudder axle. I will use a large 78mm dia ceramic bearing on which the quadrant will rotate in max plus or minus 24 degrees of angle. Together it will look like this:

    buoyancy of trimtab: I have thought about giving it positive buoyancy and have a conical bearing at its upper part.
