We arent sure. We know they are required for true current measurements,
but for our initial test in the chesapeake bay, we may go without, so that
we don't get fouled by all the shallow water and junk down there.
>Also, I'm curious what speeds you normally see from your buoys.
Although we have material for 8 buoys, none are in the water yet.

The GPS and APRS format includes the GPS's estimate of CSE/SPD, but as you
say, that could be quite useless. But for our chesapeake bay stuff, we
will get enough hits to have a pretty good track for calculating it from
position.
Thanks for your comments. As we get into this we may want to compare notes.

Will the lies never end?
When Dick's server began accepting weather data from CWOP, both findU
servers connected to his server to provide the greatest possible
reliability. A few months ago, apparently as part of their decision to
prohibit full feeds, the link stopped providing data. At that point I
removed it from findU's connect list, but the reason was because the data
was no longer being allowed to flow to findU by the Tier two sysop.
