The best part in my brief skimming is that safe boating is about risk management...not just random safety initiatives aboard.
Unfortunately, to fully grasp risk management, you have to have a concept of how real emergencies start, grow and finish along with how they compound one another.
During WWII, the Navy was pretty good at damage control and firefighting....but they weren't nearly as good with the newer vessel size and construction and dewatering during firefighting. The enormous amounts of water pumped into the vessels caused lots of issues.
So even the "experts" sometimes don't see the big picture till after it al happens.
Little emergencies aboard quickly grow during darkness and foul weather. Every little task becomes much harder to accomplish.
So while reading about new gear and resolving emergencies, always try to superimpose other emergencies or difficulties on top to simulate reality.
Simple emergencies are often quickly handles by even the inexperienced.....compound even the simple and they can even get away from the old salts.
