1. At the first step in the course of study on the establishment of job standard in an emergency, we started to measure G M of life boat of each condition, -3.61ft for light condition, 2.32ft for her boarded with reguler erew, 2.35ft for her same condition but setting oar out side, and 1.27ft for full load condition. 2. It's a matter to be checked and trained to set crew over 45 member for their fittest position in a boat in an emergency, and keep her posible stability by their rational pose and motion in boat with such small G M. 3. Another experiments are going.
