Ok, so at the dock party after the race last night, one fellow was trying to figure out what his LPS for lack of better way to put it was. He as told there were two ways, if you did it one way, his boat came out to about 115* or there abouts, another in the 130's. To get a cat 1 PIYA cert, you need to be over 120. so he was trying to figure out what formula to use. I have seen this one at USSailing, puts me at about 117 or so. Not sure where this guys boat is, ie a Farr 1020.

Google searching gets me lots of articles, but only the following ussailing link. I did find an excel program using some STIX figures, but not sure I can find ALL the numbers they want and need.

Angle of Vanishing Stability
So in the end, is there another BETTER formula program online that might do a better job estimating ones LPS?
