Testing light winds performance (10 kts):
On a broad reach the ship is really fast, around 6.5 kts. I would note that the weather-related UI predicts only 3-4 kts, which isn't for this ship or anything. But it is still a big difference.
When tacking, I started the evolution at 4 kts. It took me 5 minutes to get into the eye of the wind, then I got bored of waiting and pressed the time acceleration button. The ship eventually tacked but made plenty of sternway. Maaaaybe realistic but also pretty brutal for gameplay.
I think we have a funny situation where speed and windward performance are still way better than the release build, but tacking is still difficult.
Maybe it would also be worth increasing the rotational pressures of sails that are flat aback? Falling off (after mainsail haul) is a bit slow I think.
