Wouldn't you know it, as I was driving around, I spotted another ship in Boston. But this one was in dry dock for repairs. The USNS Capella is the seventh ALGOL - class fast sealift ship and the second ship in the Navy to bear the name. Ships in that class are the world's fastest cargo ships. Speed of 33 knots.
WOW, that's really moving for a 946 foot ship!
