The Friends of Fort Knox are sponsoring their annual “Pirate Day” at the Fort Knox State Historic Site, Prospect, Saturday, July 16, from 10 a.m. to 4 p.m.

In addition, the professional pirates of the Dark Rose and their vaunted ship the “Must Roos” will be plying the waters of the Penobscot River, letting loose cannon fire at the pirate cannon battery at the Fort. New this year will be an opportunity for a limited number of guests to sail on the “Must Roos” pirate ship.

This is the ideal event for all those who have harbored a secret desire to be a pirate. Those wishing to participate in this event are asked to don their best pirate costume and practice pirate speech and accent. The pirates will engage in a cannon firing demonstrations, sword fighting, gun play and creating general mayhem.

The Friend’s “Pirate Day” will feature several contests to include best-sounding pirate, best-dressed pirate, a pirate parade and a treasure hunt. The schedule for “Pirate Day” contests follows:

11 a.m. — Captain Crudbeard’s cannon shooting lesson

Noon — Pirate parade and costume contest

1 p.m. — Pirate ship attack with cannons, flintlocks and cutlasses in front of the fort

1:45 p.m. — Talk Like a Pirate contest

2:15 p.m. — Treasure hunt

3 p.m. — Pirate weapons demonstration with grappling hooks, pikes, boarding axes, whips, swords, pistols and blunderbuss.

Sail on the Pirate Ship Must Roos with cannons and flintlocks — six passengers max. Cruise times: 9 a.m., 10:15 a.m., 3:15 p.m., 4:30 p.m., 5:45 p.m. and 7 p.m. The charge for the pirate ship sail is $20 per person for an hour cruise and cannon firing. The ship leaves from the Bucksport Town dock and tickets may be purchased in advance by calling 469-6553. Advanced purchase is recommended, as the ship can only carry six passengers.

Those planning to attend the event are encouraged to form car-pools as there is limited public parking at the Fort. Visitors may want to bring a picnic as there will be no food other than snacks in the gift shop. An event donation of $3 per person is requested, above the regular fort admission fee, to cover the cost of hiring the pirates.
