Could that cabin renewal be postponed for the winter? The cabin is not needed to make the rig work (but the foredeck must be ok). I am asking because time is running, and if sailing has some priority, it is best not to rip the boat apart now. There will be enough to do anyway.

PS: It should be piece of cake to add a wooden top section to that 6m mast tube, but it takes a bit time. Everything takes time. Tic-tac tic-tac...
