If I understand the question right, one of the questions was how to prevent hooter halyard twisting near the hound.....

On my Stiletto 27's Hooter set up, one of the previous owners welded a piece of 1/4 inch x 4 inch stainless rod to the top of the upper swivel at a 90 degree angle. This piece of rod is covered by sliding a piece of hose over it to protect the mast and simply acts as a stop so the top of the swivel can not rotate as the bottom does.

This approach is simple very effective and allows the whole Hooter assembly to be hoisted or dropped, as simply as a non-furled system.

Just a thought.
