[Rhodes22-list] Centerboard won't drop/ control line size

[peter beckerman]

Hi All,   I've got a problem with my centerboard not dropping, so yesterday I pulled the centerboard cap and had a look. I was expecting to find a tangled mess, but to my surprise things looked pretty good (except for the dead fish).  Upon closer inspection I find that the blocks on the centerboard seems to be a tad small for the diameter line running through them.  The blocks attached to the centerboard seem to be about 5mm (or 3/16"), while the blocks on the centerboard cap look to be about 8mm (or 1/4").  The line measures about 7-8mm and maybe a tad swollen down near the blocks (under the water line).  It's pretty hard to get the line to run through the smaller blocks and I can find nothing else that might be fouling the centerboard, sooo:  what size line is supposed to be used for controlling the centerboard?
Thanks,    Peter
