I came across this article
, which seems to indicate people jumping or falling overboard seems to be on the rise. Thought this was interesting. Hard to believe though someone could accidentally fall overboard if just standing on the deck, given the height of the rails.
Like the article states, I could believe suicide may be a factor, since in some cases, they have to actually jump forward, to clear decks below, if they climb the rails, as opposed to jumping straight down.
