Yes, there is. In the debug file one of the entries at the end of the list is the count. I can´t remember the name now (away from game computer), but it has some "naval" or "england" on it. It's in the end of the list anyway. Just for curiosity, the number of ships sunk required was the size of the Spanish Invincible Armada that tried to invade England, but was defeated. In fact it was defeated much more because of the weather than to English action.
