As promised 2 weeks ago some more detailed shots of the rudder mounts:
Two of four windows are glued in. We’ve cut them with a jigsaw from polycarbonat (makrolon) and glued them in with a special glue for the wind shields of cars. Worked really well and no screws required.
The remaining two windows will go on as soon as the weather switches back to summer mode.
Had time to put the spars (at least parts of them) and the sail on the proa for the first time. Even performed some test shunts. Works all very smooth, time for the finish now!
