I know a sailboat owner who says power boat drivers are assholes. I thought they were just being rude until I locked through a canal with them. Holy shit can those people be stupid. Just throw it in reverse without looking behind me. What could go wrong? Sailboats have a lot less control going backward. Because of the rudder, the motor is often mounted off-center. You can go mostly backward, but straight back involves vectoring, and on a small sailboat the extra passengers throw off your groove, not unlike how you have to brake a little earlier when you have a full car of people versus just yourself.

That said, I was under the impression that big yachts like these actually had a professional at the wheel. The article doesn't seem to make any comment on whether a pilot was on the bridge or the owner. If it wasn't obvious from my first paragraph, I'm suspecting the latter.
