Agreed regarding the "non-necessity" of a wind speed indicator, just would be nice to have since I log everything to an SD card for post-run analysis.

What refresh rate are you running at? I've noticed that the SD card is pretty slow, so writing to it too often slow down the whole thing.

I'm also thinking that a SOG indicator is in order. The GPS produces that, but it's not continuous enough to be able to play optimization games with sail position.. At that point, a wind speed indicator *would* become necessary, as you'd need to know whether a speed up/slow down was the result of a sail change or a wind change..

I use the Sparkfun OpenLog (which is double buffered) and a serial connection for data logging, so SD card write speed is not a problem.
