Is there a specific distance that those top blocks need to be mounted up the mast?
They aren't mounted on the mast - they're attached to the foot of the main via a shackle - they go down with the sail as it comes down. Look at the diagram. It's very easy to use - you pre-load the double blocks with the larger rope that going into the cleats on either side of the mast. that is a 16:1 system. Works awesome on the Wild Cat and Tiger. I've never rigged one on an H20 but I'm sure other's can chime in.
