I also thank you. Have not made it through your detailed stability lecture notes but will work my way through them.
Like John I also did a 2 week voyage on the sail training ship Spirt of New Zealand in 1986 and also was told about the knock down. There was also some suggesstion that an engine room ventilation hatch?? was open and she started taking on water.
Anyway Sprit of NZ also did offshore trips but until just recently has been confined to more sheltered waters due to age related wear and tear. She has recently had a major referbs to get her back to being offshore capabile. (averages 340 sea days per year so is very active).
