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 ------------------------------------------------------------------- 1.
