Boatbuilding More Progress by John Z on his Classic Moth

0

Hull panel offsets for the Mistral can be found here.


In the ongoing coverage of John Zs Classic Moth build, last week I stopped over at his shop to gauge his progress and have a beer. The Classic Moth modified Mistral design is now upside down awaiting gunwhales and a layer of 4 oz. glass over the bottom.

This photo, though perhaps a tad distorted, shows how deeply Veed the Mistral design sections are around the midships.

A man and his workbench. John graciously took down a Marblehead RC sailboat he built many years ago so I could take a closer look.


A man and his workbench - take 2.


From the previous photo, you can see that John has some interesting stuff hanging from his walls. This is the box containing his F1 rubber-band indoor airplanes. These are extremely finicky to make, with a minimum weight of one gram. John has all the various tools to test balsa density and strength; tools to strip balsa into extremely narrow widths; tools to check rubber band elasticity; molds to make the tricky propellers, and the various techniques to apply the ultra-thin microfilm covering.  To make a F1 takes a methodical, painstaking craftsman.


John also has two half models of the Americas Cup, IACC keelboats, the class that precedes the current foiling catamarans. Surprisingly, it was through his wifes connections and not his Naval Architect circle of friends that these two half-models now grace his shop.

  • Mistral Hull Panel Offsets
  • and the Mistral Hull Section Offsets
I received an inquiry; "How do you actually assemble the hull? Again, I turned to master builder, John Z, and he supplied the following short PDF of photos and captions detailing at least the first assembly stages of a Mistral Classic Moth build project.

Mistral Y2K Section Offsets Via John Z

0

I mentioned when I published the offsets for the Mistral hull panels that you still needed some bulkheads to bend the panels around. John Z. immediately shot me, via email, the section dimensions he measured off his very fast Y2K Mistral. They are taken every 305mm to give an even 11 sections over the length of the hull. (Station 3353 being the transom, sitting on the aft end of the hull panels). John used every other section inserted in his panels when he bent them up to set up the hull shape. It must be noted that 3 bulkheads are left in the hull before decking and two of them dont exactly lie on station spacing given (the forward edge of the aft deck being the exception, it usually aligns with Station 2743.).
