I was out with the Coast Guard today for work. I used to get out on the water a lot more as part of my job, but not so much these days. But it was nice to join the crew of the USCG Cutter Seahorse for a run out past Cape Henry to the Atlantic Ocean.
You never know what you'll see out there. Today it was a nuclear powered submarine. What kind I don't know. Maybe a Los Angeles class fast attack submarine, I believe there are some based at Naval Station Norfolk. What you see there is called the "sail" of a submarine. I've heard people call it the conning tower, but in military terms it is the sail.
I did get some of the crew to answer a small boat safety question I've had for a long time. It was about the flares required on the boat. I purchase a new set when my current set expires. My instinct was to carry both the new flares and the expired set of flares. Is there any problem carrying expired flares on a boat? They said they were fine, in fact it was a good idea to have as many flares on board as practical, as long as there were enough - three - current flares. So I'm in good shape there. And I hope I keep my track record of never having to use one of them.
