No, this is a new ship. The Hornblower series used the Grand Turk, a Turkish built replica of a 1741 vintage Royal Navy 6th rate frigate. While the ship has a good appearance, the construction methods are largely modern. The Hermoine is built as closer to original as is possible with currently maritime regulations. The Grand Turk has been renamed and is in France.
The ship used in Master and Commander is a replica of of a Royal Navy Revolutionary era 6th Rate 24 gun frigate, HMS Rose. That ship is moored in San Diego.
Thank you for the reply! Very interesting. I didn’t know there had been several replicas of the old ships built. Worth researching.
It is at Yorktown - A good drive from DC, but it will be worth the trip and overnight stay.
The Australian built Endeavour Replica was also used in Master and Commander and was actually sailed around Cape Horn with a film crew aboard to get B roll footage.
As a replica, Rose is pretty sad - steel hull and fake molded rubber rope "Rigging" at deck level and fake guns on one side only. Endeavour is built entirely of wood, is rigged traditionally but with synthetic rope made to emulate the appearance and feel of hemp and has real, functional, six pound guns mounted. I don't know about Hermione.
