Thanks Tim for the great info.. I had just found the sailcalc site
yesterday and was using it to check out some of the boats that my wife and I
have been thinking about.. The tide program is pretty neat too.. I have
one on my Palm Pilot so it's nice to find one for the pc as well..

Hi -

I've been looking for opensource software related to sailing for a
while. I haven't found too many linux specific programs related to
navigation - not too much that's useful anyway, but I have found some
opensource java software that's related to sailing and very useful.

In particular, I'd like to draw your attention to jtides
(www.arachnoid.com/JTides/ ) which is an excellent tide table
approximator. I say approximator because the creator included a
general disclaimer stating that it's results are not to be used for
navigation. In my experience, its as accurate any proprietary product
I've seen.

I've also found some java based calculators for site reduction and
such. I don't recall the site where I found them. Finally, Sail Pro
is pretty cool. http://www.image-ination.com/sailcalc.html.

Hope this is helpful
