Just took mine apart
Just took mine apart to replace one of the sheaves. Mine has the three Merriman single blocks mounted to the boom, a single block with becket on a spring mount on the port side of the top of the cabin, and a double (fiddle) block on the starboard side of the cabin top. The sheet fastens to the becket on the port-side block, runs through the center block on the boom, through the smaller (innermost) block on the starboard side, back through the stern-most block on the boom, through the single block on the port side, through the forward-most block on the boom, and down through the larger (outward-most) block on the starboard side, and back through a locking cleat to the cockpit.Jon Zaimes"Airwaves"
