My view....
Light wind (and I mean LIGHT so 0-2 kts, when the spi is almost not working).
Plates up about 50%, sail deep, around 90 to apparent wind.
As soon as the boat starts to move "properly", so maybe 3+ start to drive for speed as the F16 is light and has large sails you can build apparent wind as soon as the sails are working properly. Plates stay up around 25%
As soon as the hull starts to lift a little, plates down.
