4 blocks?
When I bought the boat it had 2 jib sheet blocks. I have since replaced these. How would you use four blocks? Yes, the blocks attach to the toe rail. I set mine so the the sheet comes off of the sail at 45 degrees (i.e. a line dividing the sail equally.) Granted, moving the blocks would be more efficient, if you are worried about things like that. With a 10 knot wind on the beam or forward and she will give her all.Andy"Baroque"
