Jono,
Thank you for pointing out the similarity in 'asking' prices. After speaking with the listing broker and reviewing the Yachtworld listing, it is worthwhile noting the asking price of The Wizard of Bristol includes delivery anywhere in the world which addresses the concern addressed in the original post.
With regard to the rig, Marilee's 2016-17 restoration took the novel approach of building the class original gaff rig, and the following year a racing marconi rig updated by LFH (1936). One of the photos on the Wizard's yacht world page shows the 30's vintage marconi rig. Marilee's owner changes rigs based on the perceived advantage for the upcoming season/events.
With regard to the bulwark, I don't believe the intent for this restoration was to race the boat on the Newport-Antigua-Med circuit.
Are you still actively involved with Chinook? Perhaps you could share insights on your choice of location for restoration, hull shape, and project management.
