On the subject of 'Thunder Bomb', there have been quite a few vessels in the Royal Navy called Thunder, nearly all Bomb Vessels (which were usually named for volcanoes, or with names like Explosion or Terror). A vessel was often called by name followed by rating, such as Diana Frigate or Cruizer Sloop. They usually carried two large mortars (up to 13inch) and were used for shore bombardment. Bomb vessels were responsible for the 'bombs bursting in air' that them Americans are always going on about. And bomb vessels were selected (because of their stout construction) for 'Lord' Franklin's ill-fated expedition.

They were commanded by a Master and Commander, an Admiralty appointment so it is not permissable for a ship's captain to appoint anyone to the command of one of these vessels, especially if they were a known murderer and a woman.

On a more sensible note I've always preferred the last verse used in some versions:

So, come all young men from Wells and London
If 'twere served the same as she
It's very sad would be young women
Very scarce young men would be.
