40-400: A credit report is not actually a credit score but rather a code that indicates the payment status of that account. Payment status affects your credit score, however, and an R9 status code is bad. It means the creditor considers your debt uncollectible.

80-405: A keel uses the forward motion of the boat to generate lift to counteract the leeward force of the wind. As a counterweight, a keel increasingly offsets the heeling moment with increasing angle of heel. Related foils include movable centreplates, which -being metal- have the secondary purpose of being a counterweight, and centreboards and daggerboards , which are of lighter weight, do not have

100-434: A series of pre-fabricated, complete hull sections rather than being built around a single keel, so the shipbuilding process commences with the cutting of the first sheet of steel. The most common type of keel is the "flat plate keel", which is fitted in most ocean-going ships and other vessels. A form of keel found on smaller vessels is the "bar keel", which may be fitted in trawlers, tugs, and smaller ferries. Where grounding

140-767: Is different from Wikidata All article disambiguation pages All disambiguation pages USS R-9 USS R-9 (SS-86) was an R -class coastal and harbor defense submarine of the United States Navy . R-9 ′s keel was laid down on 6 March 1918 by the Fore River Shipbuilding Company, Quincy, Massachusetts . She was launched on 24 May 1919, sponsored by Mrs. Irving E. Stowe, and commissioned on 30 July 1919. Following fitting out and shakedown, R-9 , given hull classification symbol SS-86 in July 1920, operated along

160-407: Is possible, this type of keel is suitable with its massive scantlings , but there is always a problem of the increased draft with no additional cargo capacity. If a double bottom is fitted, the keel is almost inevitably of the flat plate type, bar keels often being associated with open floors, where the plate keel may also be fitted. Hydrodynamic keels have the primary purpose of interacting with

180-405: Is the bottom-most structural member around which the hull of a ship is built. The keel runs along the centerline of the ship, from the bow to the stern . The keel is often the first part of a ship's hull to be constructed, and laying the keel , or placing the keel in the cradle where the ship will be built, may mark the start time of its construction. Large, modern ships are now often built in

200-457: The Kyrenia ship establishes the origin of the keel at least as far back as 315 BC. The Uluburun shipwreck ( c. 1325 BC) had a rudimentary keel, but it may have been more of a center plank than a keel. In carvel-built hulls, construction began with the laying of the keel, followed by the stern and stem . Frames were set up afterward, set at key points along the keel. Later,

220-522: The keelson was attached to the keel, either bolted or with treenails . A plank first building system that is still in use today is clinker construction , using overlapping planks which are shaped to produce the hull form. Older systems include the bottom-based method used for the planking on either side of the keel of a cog (and also in Dutch shipbuilding up to and including the 17th century). This involves flush-fitted planks that have been cut to provide

240-565: The New London area for most of the remainder of World War II . In late March 1945 she moved south again, trained with destroyers , destroyer escorts , and escort carriers off Cuba and southern Florida . Then, in mid-May, she returned to New London. On 20 September R-9 proceeded to Portsmouth, New Hampshire , where she decommissioned on 25 September 1945. Struck from the Naval Vessel Register on 11 October 1945, she

260-648: The Reserve Fleet. In September 1940 R-9 was placed in reduced commission, then moved up the coast to New London where she completed activation and was placed in full commission on 14 March 1941. Within two months R-9 was en route to the Caribbean Sea and duty under Commander, Panama Sea Frontier. Arriving at Coco Solo on 27 May, she patrolled the approaches to the vital inter-ocean canal with SubRon 3 into October, then returned north to New London for overhaul arriving on 23 May. During December she

280-879: The northeast coast primarily in the New London, Connecticut — Newport, Rhode Island area until 1924. Ordered to the Pacific in March of that year, she arrived at Pearl Harbor , her new homeport, on 4 May. Operations and exercises, from individual to fleet in scope, occupied the next six and a half years and on 12 December 1930 she got underway for return to the Atlantic. Retransiting the Panama Canal in mid-January 1931, she arrived at Philadelphia , Pennsylvania , on 9 February and reported for inactivation. Decommissioned on 2 May 1931, R-9 remained at Philadelphia, berthed with

320-463: The shape of the hull. Still older is the mortice and tenon edge-to-edge joining of hull planks in the Mediterranean during the classical period . In this system, much of the strength of the hull is derived from the planking, with the frames providing some extra strength. In all these systems, the joining of the keel, stem and sternpost are the starting point of construction. A structural keel

340-411: The water and are typical of certain sailboats. Fixed hydrodynamic keels have the structural strength to support the boat's weight. In sailboats , keels serve two purposes: 1) as an underwater foil to minimize the lateral motion of the vessel under sail ( leeway ) and 2) as a counterweight to the lateral force of the wind on the sail(s) that causes rolling to the side ( heeling ). As an underwater foil,

360-704: Was attached to the Submarine School but, with the new year, 1942, the submarine proceeded to Casco Bay, Maine , for operational training. From mid-month on, through the U-boat offensive of 1942 and early 1943, she rotated between New London and Bermuda to patrol the shipping lanes which transited the Eastern Sea Frontier and the Bermuda Patrol Areas. Shifted to ASW training programs in the spring of 1943, she operated primarily in

380-598: Was referring to the three ships that the Saxons first arrived in). Carina is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove , a suburb of Sydney, Australia , where careening was carried out in the early colonial days. The use of a keel in sailing vessels dates back to antiquity . The wreck of an ancient Greek merchant ship known as

400-513: Was scrapped in February 1946. Keel The word "keel" comes from Old English cēol , Old Norse kjóll , = " ship " or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work De Excidio et Conquestu Britanniae , under the spelling cyulae (he
