Which wind criterion do you need?
There are several wind criteria available in Delftship. The screenshow below shows how to limit the upper angle to the lesser of 40 degrees or the downflooding angle (red circle).

The blue ellipse shows the settings for the rollback angle. There are several options:

  1. Use the rollback angle as defined by the IMO
  2. Use a fixed rollback angle. Starting from the intersection of the wind heeling lever with the stability curve the ship rollsback a specified amount of degrees.
  3. Specify a “Roll back to” angle. The ship rolls back to the specified angle. I assume you need this last option.
