Oh yes^ read this, the skipper died so did his daughter. Plus his wife and son were critically injured when their boat went out of control and he didnt have the lanyard line attached, they were cut to shreds in the water after the boat turned violently and chucked them out and got stuck in a circle going round and round and hitting them.

Ive read stories of people having their steering snapped and they are thrown out of the boat in a milli second, the motor instantly flicks to hard lock and throws people out. If they are unconscious they drown. This isnt just a concern for the older rope pulley style steering systems but also the newer systems which if not maintained properly have failed too. One case i read was one which had a slow leak of oil and it went unnoticed and it failed killing two people on board.
So i dont let anyone drive my boat without it on, im not so fussed about a lifejacket, thats their decision but the lanyard is a decision for everyone on board
