Firstly, wow – that looks like a bit of work, but worth it I am sure.
I have shackled the forestay directly to the bow fixing, although I will admit it was quite cosy! I think I might take a look at moving it over to something less tough, just in case tension is too high. Anyone care to suggest how tight it should be? Is there a way to measure it given it is, currently, a fixed length which seems to be about the right length?
