I agree with Richard- what a voyage! This boat looks excellent and almost bomb-proof in appearance: really strong. The wind-vane self steering mount looks solid.
The sail seems to have been sewn in an interesting way, with certain panels made up of quite small sections. Almost like a patchwork. Whereas other panels seem to have seams that run in horizontal sections along the battens.
This JRA forum is so useful to draw our attention to documents like this that would otherwise be missed, at least by me.
As a fellow 20-foot junk sailor, these voyages of Robin's are inspirational.
