and there are about 3 threads left, and it seems to be working fine. Any "binding" I am having I think is due to the blocks along the way in the furling line... in fact I noticed one of the harken blocks was cracked and may be broken inside. But the furler unit itself spins quite freely and nicely. I have to work on routing the furling line better... especially the last block, which has about 270 degrees of wrap. (not good)
Due to the location of that last block (the cracked one) I think I might go to a larger diameter to help ease the stress on it.
Thanks for looking out for us folks on CSBB.
