Marchaj fishing boat data?

I'm looking for the data gathered by C A Marchaj in wind tunnel
tests of sails for fishing boats (bermuda, lug, sprit, lateen,
crabclaw). I've searched the online catalogue of the Canadian
Institute for Scientific and Technical Information here in Ottawa,
and the University of Southampton website without success.

I'm wondering if anyone could tell me if the data appears in any
of the publications below. I'm interested in what he found out
about sprit sails because I like to put them on my home made
boats. I'm half way through his "Sail Performance" on loan from
the Ottawa public library in which I found out about the
exsistence of the data. "Sail Performance" is heavy going but very
informative and does not use any math beyond basic geometry and
trigonometry.

thanks

Since an explicit assumption of the study was that fishermen would not
be willing to learn to sail, the results could hardly be useful to
anyone who has done so.

What have you found informative in "Sail Performance"? I have all the
background to read it easily but found nothing useful.
