      Hi Bruce,

      Thanks for your thoughts. I was able to get a copy of the MAIB
      article as well as the later one where John Hadden built Queen Mab in
      strip built method.

      I'm still leaning towards lapstrake although the comments of Dave T.
      were very interesting. Light does seem better. I'm thinking 3mm ply
      over 3/8ths frames. Let's face it, this is not a cargo hauler.
