I was sailing up to Vancouver from Mexico a couple of years ago in a 43' ketch-middle of the afternoon, I am alone on deck and I see a black post off the port beam, we were in 12,000 feet of water, as we come abeam of it I realise there is an aperture just down from the top of said "post". We had been motor sailing and I guess the sub picked up our engine noise. Last year, sailing up from Hawaii, in the middle of the n.Pacific a warship suddenly appears on the horizon and passes close astern.
