jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..I have to still assert that my statement was correct. GPS speed is speed over ground. True wind is wind speed over ground. Of course... -
jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..Right. I'm assuming my observations had a high degree of error. In fact, I didn't even write them down: this is just from memory. I...

Ddlochner replied to the thread Old ST60 with new transducer: wind speed is reading quite high..As a mathematician you know n=1 studies are pretty weak. Multiple trials under different conditions will yield a more robust data set.

jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..So I'm actually a mathematician by trade, and I think the math here is pretty straightforward, so let's write down the equations (which...
-
jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..Since I'm measuring apparent wind, current is irrelevant. I'm just comparing speed over ground (from the GPS) with wind speed detected...

jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..Yeah: I agree. I've had the anemometer on and off over the years, and now put a new one on. Nothing should have changed. It was working...

jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..That's a good idea, but since 1 m/s = 1.94 knots, it would be reading slower, not faster. So that can't be it. I also just checked at...

jaysweet replied to the thread Old ST60 with new transducer: wind speed is reading quite high..Right. What I was noting was that heading into the wind, I should observe 5.5 + x, where x is the true wind speed, and 5.5 - x heading...

Here’s another interesting use I don’t think we really reconized when this thread started - I took all of the manuals I had as PDF’s for... -
Ward H replied to the thread Old ST60 with new transducer: wind speed is reading quite high..Was there any current running while doing your test? If so I'd expect the current is causing the up current / down current readings to... -
Greetings all, I'm considering a sailboat in Marina del Rey and I'm looking for a comprehensive prepurchase survey. Can anyone...

Less than two years after this thread was started I have a sailing related AI use case that would’ve been pretty unimaginable then - I...
