Q-ships, also known as Q-boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q-ships the chance to open fire and sink them.
A schooner is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner.
USS Captor (PYc-40), briefly the seventh ship to bear the name USS Eagle (AM-132), was a Q-ship of the United States Navy.
A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
USS Providence was a sloop-of-war in the Continental Navy, originally chartered by the Rhode Island General Assembly as Katy. The ship took part in a number of campaigns during the first half of the American Revolutionary War before being destroyed by her own crew in 1779 to prevent her falling into the hands of the British after the failed Penobscot Expedition.
HMCS Sackville is a Flower-class corvette that served in the Royal Canadian Navy and later served as a civilian research vessel. She is now a museum ship located in Halifax, Nova Scotia, and the last surviving Flower-class corvette.
Princess Royal was a British merchant ship and blockade runner that became a cruiser in the Union Navy during the American Civil War and later returned to civilian service.
USS Winchester (SP-156) was an armed yacht that served in the United States Navy as a patrol vessel from 1917 to 1919. Prior to and following World War I, Winchester was a private yacht, later renamed Renard. In World War II, Renard was requisitioned for use in the Royal Canadian Navy as a patrol vessel, keeping her name. She was returned to her owners in 1944.
The CSS Tallahassee was a twin-screw steamer and cruiser in the Confederate States Navy, purchased in 1864, and used for commerce raiding off the Atlantic coast. She later operated under the names CSS Olustee and CSS Chameleon.
Bowdoin is a historic schooner built in 1921 in East Boothbay, Maine, at the Hodgdon Brothers Shipyard. Designed by William H. Hand, Jr. under the direction of explorer Donald B. MacMillan, the gaff-rigged vessel is the only American schooner built specifically for Arctic exploration. She has made 29 trips above the Arctic Circle in her life, three since she was acquired by the Maine Maritime Academy as a sail training ship in 1988. She is currently owned by the Academy, located in Castine, Maine, and is named for Bowdoin College.
USS Pontiac (AF-20) was the Danish refrigerated cargo ship Australian Reefer that sought refuge in the neutral United States when Germany occupied Denmark in April 1940. In 1941 the United States seized 40 Danish ships idle in its ports with Australian Reefer being among those ships.
USS Tuluran (AG-46) was under construction for the British at the Toledo Shipbuilding Company as the cargo ship War Bayonet in 1917 when requisitioned by the United States Shipping Board (USSB) for World War I service. The ship was launched and completed as Lake Superior. The Navy acquired the ship from the USSB with assignment to the Naval Overseas Transport Service (NOTS) with the identification number ID-2995. The ship was returned to the USSB which sold the vessel in 1926. The ship was renamed C. D. Johnston III and that vessel operated out of Oregon until again sold and based in San Francisco. Another sale resulted in the vessel being renamed Anna Shafer which was acquired by the War Shipping Administration (WSA) in 1942 and allocated to the Navy for World War II service.
Young Teazer was a United States privateer schooner that captured 12 British vessels, five of which made it to American ports. A member of her crew blew her up at Mahone Bay, Nova Scotia during the War of 1812 after a series of British warships chased her and after HMS Hogue trapped her. The schooner became famous for this deadly explosion, which killed most of her crew, and for the folklore about the ghostly "Teazer Light."
HMS Mackerel was a Royal Navy Ballahoo-class schooner of four 12-pounder carronades and a crew of 20. The prime contractor for the vessel was Goodrich & Co., in Bermuda, and she was launched in 1804. Given that she served entirely during the Napoleonic Wars and the War of 1812, she had an unusually peaceful and uneventful career, primarily on the Newfoundland Station, before she was sold in 1815.
Blue Dolphin was an auxiliary schooner built in 1926 at Shelburne, Nova Scotia by the Shelburne Shipbuilding Company as an adventure yacht. She served as US Navy auxiliary, IX 65 in World War II and as a postwar research vessel made famous by a Stan Rogers song.
USS Bagheera (SP-963) was a United States Navy auxiliary schooner that served as a patrol vessel. She was in commission from 1917 to 1919.
USS Rogday (ID-3538) was a United States Navy icebreaker and cargo ship in commission from 1918 to 1919.

The schooner was sold to private interests following the war and renamed Alfred & Emily before being lost by fire in 1951.
USS Charles Whittemore (ID-3232) was a four masted lumber schooner used as a decoy ship against German U-boats during World War I.
