Seacat or SeaCat may refer to:
A bicolor cat is a cat with white fur combined with fur of some other colour, for example, solid black, tabby, or colourpointed. There are various patterns of a bicolour cat. The coat patterns range from the Van-patterned, which has colour on the tail and crown of the head, to a solid colour with a throat locket or medallion. Bicolour coats are found in many cat breeds and are in domestic longhair and domestic shorthair cats.
Gulls, or colloquially seagulls, are seabirds of the subfamily Larinae. They are most closely related to terns and skimmers, distantly related to auks, and even more distantly related to waders. Until the 21st century, most gulls were placed in the genus Larus, but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews; this still exists in certain regional English dialects and is cognate with German Möwe, Danish måge, Swedish mås, Dutch meeuw, Norwegian måke/måse, and French mouette.
The black-headed gull is a small gull that breeds in much of the Palearctic in Europe and Asia, and also locally in smaller numbers in coastal eastern Canada. Most of the population is migratory and winters further south, but many also remain in the milder areas of northwestern Europe. It was formerly sometimes cited as "common black-headed gull" to distinguish it from "great black-headed gull".
The great black-backed gull is the largest member of the gull family. It is a very aggressive hunter, pirate, and scavenger which breeds on the coasts and islands of the North Atlantic in northern Europe and northeastern North America. Southern populations are generally sedentary, while those breeding in the far north move farther south in winter. A few also move inland to large lakes and reservoirs. The adult has a white head, neck and underparts, dark blackish-grey wings and back, pink legs and the bill yellow with a red spot.
The great skua, sometimes known by the name bonxie in Britain, is a large seabird in the skua family Stercorariidae. It is roughly the size of a herring gull. It mainly eats fish caught at the sea surface or taken from other birds.
Sea Wolf is a naval surface-to-air missile system designed and built by BAC, later to become British Aerospace (BAe) Dynamics, and now MBDA. It is an automated point-defence weapon system designed as a short-range defence against both sea-skimming and high angle anti-ship missiles and aircraft. The Royal Navy has fielded two versions, the GWS-25 Conventionally Launched Sea Wolf (CLSW) and the GWS-26 Vertically Launched Sea Wolf (VLSW) forms. In Royal Navy service Sea Wolf is being replaced by Sea Ceptor.

Seacat was a British short-range surface-to-air missile system intended to replace the ubiquitous Bofors 40 mm gun aboard warships of all sizes. It was the world's first operational shipboard point-defence missile system, and was designed so that the Bofors guns could be replaced with minimum modification to the recipient vessel and (originally) using existing fire-control systems. A mobile land-based version of the system was known as Tigercat.
The Lun-class ekranoplan is the only ground effect vehicle (GEV) to ever be operationally deployed as a warship, deploying in the Caspian Flotilla. It was designed by Rostislav Alexeyev in 1975 and used by the Soviet and later Russian navies from 1987 until sometime in the late 1990s.

The black-tailed gull is a gull native to shorelines of East Asia.
The swallow-tailed gull is an equatorial seabird in the gull family, Laridae. It is the only species in the genus Creagrus, which derives from the Latin Creagra and the Greek kreourgos which means butcher, also from kreas, meat; according to Jobling it would mean "hook for meat" referring to the hooked bill of this species. It was first described by French naturalist and surgeon Adolphe-Simon Neboux in 1846. Its scientific name is originally derived from the Greek word for gull, "Glaros" and via Latin Larus, "gull" and furca "two-tined fork". It spends most of its life flying and hunting over the open ocean. The main breeding location is in the Galápagos Islands, particularly the rocky shores and cliffs of Hood, Tower and Wolf Islands, with lower numbers on most of the other islands. It is more common on the eastern islands where the water is warmer.
The HSC Speedrunner Jet is a fast ferry owned by Seajets thαt operates between Sitia, Kasos, Karpathos, Chalki and Rhodos. She was built in 1999 at Fincantieri, Riva Trigoso, Italy, for Sea Containers as HSC SuperSeaCat Three. Under that name she sailed on Sea Container's services around the British Isles, as well as with its subsidiaries Silja Line and SuperSeaCat on the Baltic Sea.
SeaCat was the marketing name used by Sea Containers Ferries Scotland for its services between Northern Ireland, Scotland and England between 1992 and 2004. The company was originally based in Stranraer later moving to Belfast. The name originates from the use of high-speed catamaran ferries.

Kirr is an island in the Darss-Zingst Bodden Chain south of the Zingst Peninsula on the German Baltic Sea coast. It is separated from the peninsula by the Zingster Strom. The island is a nature reserve within the Western Pomerania Lagoon Area National Park. It was formerly and is sometimes still called Großer Kirr or Große Kirr. This is to distinguish it from the northwestern part of the island, which was still a separate albeit much smaller island in the Zingster Strom in the second half of the 20th century, that used to be called Kleiner Kirr or Kleine Kirr.
