How close is too close?

Orca close

There is a marine regulation requiring boats to stay 100 meters from orca and this is enforced by Strait Watch and the Warden.  This day we were lucky to be sitting quietly as the orca were passing in shore of our boat when a female turned and left the pod she was traveling with and swam around and beneath our boat. The lucky part was that Strait Watch was sitting about fifty meters from us so we had the best witness that we were not approaching the orca.  Were we talking with them after the encounter and both agreed that the orca was likely fishing and approached our boat out of curiosity. The reason is not important the photos are what counts.  Definitely a bonus day.
