The mast is a work in progress:
Since the photo was taken the mast is now 16-sided and beginning to emerge in a roundish shape. Tools of choice are my block plane and ROS. The block plane does a good job of flattening the corners. The ROS with 40 grit paper does a good job of round(ish)ing the mast. Sessions with 60, 80 and 120 grit will follow.
As a diversion today, I weighed the mast and yard. The mast is 18'8" long and weighed in at 24.9 lbs. The yard is 12'9" long and weighs 9.8 lbs. This is considerably heavier than the yard on my GIS, but the PF yard is also larger in cross-section and is stiffer than the GIS yard.
Recently, another PF builder made me aware of a possible issue with the plan sheet describing the balance lug yawl sail plan and the placement of the mast in the boat. Some details don't make sense and we expecting clarification from John W.
