Leading lines aft
Om my C-22, I use Shaefer turning blocks on pivoting bases secured to the bottom of the mast just above the mast step. The main halyard turning block is through bolted through the mast with long #10 screws. I actually through bolt it into a second Shaefer turning block with a pivoting base using barrel nuts. This second turning block is for the tack reef.The jib halyard turning block can be done the same way only is is mounted on the aft flat side of the mast as opposed to the forward flat side for the main halyard.As these turning blocks swivel, I then aligned placemant of cheek blocks to turn the lines towards the cockpit and down along the sides of the handrails.Finally I installed rope clutches and cleats accordingly.Hope this helps.
