Years ago near Pt. Defiance (Tacoma) we were salmon fishing out of a 14 foot rental skiff and a pod of killer whales moved in. One bull got so close I could have touched his 6 foot dorsal fin. The fishing action dropped off to zero.
Back in early 2000, I was sent to Camp Rilea in Astoria, OR to conduct some training. I went for an early morning jog on the beach and way up ahead, I saw what I thought was an end table sized boulder sticking out of the sand. As I got closer I realized it was the head of a basking shark, after which looked out to the water and noticed a few orcas frolicking a couple of hundred yards off shore.
I’ve heard of sea lions boarding boats in situations like that.
