This might upset some , but...I beleive it is the responsibility of every skipper to ensure the safety of his own boat and crew. How dangerous? for me the fact that lives are lost on a somewhat regular basis should be sufficient warning as to the level of danger and prompt me to take appropriate precaution. This is almost my entire reasoning for joining forums like this. To be as well infomed and prepared as possible. education and practice can help minimize the risks, but they will always be there. Knowing when to sail a particular area is part of proper planning. Making certain the boat is prepared and capable of any passage is also part of proper seamanship.
