R-class Patrol Boat
The R-class patrol boats was a class of Finnish patrol boats, originally constructed as coastal minesweepers. They were modified into patrol boats by the end of the 1960s and transferred to the Patrol Flotilla and later to the 7th Missile Flotilla. They were then used for sea patrol and as anti-submarine warfare vessels. They were stricken from the Finnish Navy list in the 1990s. The three later vessels, ''Ruissalo'', ''Raisio'' and ''Röyttä'', were somewhat larger and the vessels are therefore sometimes referred to as the ''Rihtniemi'' and ''Ruissalo'' classes. However, the Finnish Navy used the designation R class for all five vessels. The R class was much liked in the Finnish Navy, due to their low fuel consumption and their good seagoing qualities. They were in principle unsinkable (the vessels could have a list of 115 degrees without sinking and still return to upright position). Vessels of the class * ''Rymättylä'' (51) / ''Suurop'' (P 421): Ordered in July 1955 from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrol Boat
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine (" blue water"), estuarine ("green water"), or river (" brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti-smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minesweeper
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing Grappling hook, grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their ...

Vartiovene 55
''Vartiovene 55'' is a former Finnish Navy R-class patrol boat bought into private ownership and converted into a commercial cruise ship.

It was originally numbered 5, but the number was changed to 55 in the middle 1970s. ''Röyttä'' and its sister ships, ''Ruissalo'', ''Raisio'', ''Rihtniemi'' and ''Rymättylä'', were originally designed to serve as coastal minesweepers, based at Pansio.
