Paul Bieker supplied me with a tapered carbon fiber tube for the mast support. It began life as a bow spirit for an International 14. I used the top 5 feet or so for the support.
Two notches were cut in the lower end of the support to fit over its bulkhead.
The support was dry fit and the alignment was checked with the laser. I took some extra time here to get it right.
The mast support is glued in and the starboard ring frame is attached.
Both ring frames are attached here. The starboard forward bunk flat is checked for fit.
