      Jeff, I have a book describing many types of hollow wooden masts,
      including one consisting in a rectangular section with two sides of
      plywood and two of lumber (say, front and back in lumber, port and
      starboard in plywood). I'll look and post the scantling details.

      Best, Pippo
