I am trying to install a ratchet block on my 1974 sunfish. I am wondering if a fixed block will work or do I need a swivel one? Also I should use a backing plate when I install it correct?
I agree with sailcraftri - I've always used the Harken 2135 on my Sunfish.
I bought the Holt Nautos 57mm one from Intensity Sails and put that on the Minifish that my boys sail.
here is my preferred setup (for Sunfish or Minifish).
