G'day,
More cool stuff. What does the entire setup, less gps, cost please? I don't suppose you would be interested in selling or (better) hiring out yours for the northern winter?
I am getting to grips with my 7.5m proa
http://www.harryproa.com/Elementarry/SailingPhotos_4.htm and would love to be able to get the sort of pictures and information you are getting. Top gps speed so far is 16.5 knots in 16 knots of wind (I sail around the Bureau of Meteorology data station so wind speed and direction average and peak for every 10 minute interval are on line.)but there is room for a lot more when I get the rigs and handling up to scratch.
If you would like to discuss it off list, my email is
proa@iinet.net.auregards,
