This is a knot that I developed for the cases where both a forward and aft facing bight are needed.
Step 1: Start by making the bow-tie configuration as shown and insert it into the loop for constructing the bowline knot.
Step 2: Continue constructing the bowline.
Step 3: Finish the bowline.
Step 4: Take the inner long bight that formed the bowline and tie a Yosemite tie off with it, then take the single stranded tail of the rope and tie a double overhand knot around one of the loop strands. Once the entire knot is dressed nicely it is done.
The right side of this knot is setup for constructing a per-tensioned back tie and the left side was setup in the same manner as the Double Loop Bowline with a Aft Facing Bight and Clove Hitch.
