I often compare boating and flying and one thing flying does well is analyze accidents and publish information about causes. The NTSB does on thier website and most flying magazines have "never again" or "learned about flying from" articles to help educated others of mistakes made.
My flight instructor made me read reports about accidents, not to scare me but teach me even high time pilots made mistakes and not to get over confident
Seems like in the boating community accidents aren't discussed much as it may negatively impact the sport. just my opinion.
