Hi Bruce:

Sounds as though you may have some insight here. How about a "what if."
Lets say I am a US citizen sailing about 350 miles off the CA shore. I
am not flying any flags. After all, I am less than 12 meters LOA and a
recreational vessel. I just spent a few months in Peru and returning
home to Astoria, Or. A US warship says, pull over we want to board.
Can I tell them to buzz off and keep sailing?

As the Captain of a Canadian warship, I can tell you, we can't do that.
We'd need probable cause and loads of approval. We'd probably
just put some other resources on you and watch you quite closely until
we got the permission. Now, in the Persian Gulf......
