I just realized that the polars that came on my boat are way different from those on the J/Boats
website. For example, the one from the boat is dated 1994 and shows the optimal true wind angle in 8 kts of wind at 144.4. The one on the J/Boats
website has the optimal angle at 161.
Note that the newer is in apparent wind.
Anyone know where the newer came from, and if I should pay any attention to it?
