Thanks Dave for taking the time to post that, the picture is exactly what I needed to see.
If I can source a sheave and forestay fitting like yours I’m sure I could “make” them fit. Any ideas for a supllier?
PS Mast bend not an issue as she sails well enough for me, and I’ve strengthened the foredeck with fibreglass, it aint pretty but does the job. The boat has clearly been abused, reflected in the price I paid for it. At least she floats and whizzes along nicely! Almost got to the Isle of Wight the other day…..
