The soft copy of "managing Avoidance collision at sea" I did not have. However I upload the "collision avoidance 2007" on the website as picture attached. This is the original idea of my collision avoidance. You can read it first. The English writting is poor. In 2017, I wrote another copy of "close quarter collision avoidance" with full details but it is in Chinese for serious reader. I don't know anyone want to go so detailed data. The idea of "BRM for 21 century" (uploaded already) is because the case study of "Ever Smart" I had wrote three times for different target reader, one for OOW, one for Master, then I realized different level need different criteria in collision avoidance. That's why, rating, OOW, CO and Master need different knowledge and training skill.
