Re: subs
In the late 90's friends and I got on a salmon party boat, out of Berkeley, CA, and rode it through the Golden Gate. We fished off Pacifica and had a fine day with perfect weather and a limit of salmon for the boat.
We were coming back in the afternoon, and maybe a couple miles outside the Golden Gate, when I look back and see a sub surface, about a mile behind us. I yell "Holy [bleep] a sub" and point back so everyone sees the black beast behind us. The party boat is ~50 foot long, one engine, and is making perhaps 10-12 knots. In a couple miles it had closed the distance to maybe a half mile - and people were looking back getting slightly nervous. We continued on into the Gate, and a tug and two Coast Guard boats were there at the bridge, to meet the sub. It slowed at that point and met them. No idea which sub it was, or even type, but even loafing on the surface, it could easily catch us, and I gather they are even faster underwater, than on top.
