Like.
I didn't know that. And looking it up, the definitions I see on the web are pretty ambiguous, which is annoying. For example, the... -
That's a big chunk of money but you had some very substantial work done that improves the boat significantly and none of it was work... -
jaysweet replied to the thread Rigging Quote.Thanks. Somehow, it feels good to invest in the boat, whether I keep it for 20 years, or sell it to buy another. If the latter, at least... -
SycloneDriver replied to the thread Cleaning the engine???.Simple Green and a little water coupled with a "parts cleaning brush" and more water. Vacuum dry or run the motor. -

I've been sitting at the dock with the shore power disconnected for about an hour with the AC running. The Percon f3000lfp shows that...

Davidasailor26 replied to the thread Old ST60 with new transducer: wind speed is reading quite high..There is a difference between “true wind speed” and “ground wind speed”. True wind speed is generally defined, at least by the...
-
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...
