Is that what I think it is .... ???

We saw our first submarine in the Sound on the day we arrived, but were exhausted from hauling boxes upstairs, and thought perhaps we were hallucinating. Bob told our friends in London that evening, but was met with reactions such as "hmm .. how much wine have you had/oh yeah, right!!", and as we were not quite sure what we had seen, the next time we saw one, I had the camera ready. We have now seen quite a few of varying sizes, some are actually nuclear ones, others are not. Often the larger ones are escorted by several tugs and a couple of RIBs, who escort the sub through the deeper channels (obviously!). Apparently there is another 30 feet underwater below what can actually be seen, so the channels would need to be deep.
