Query: How do man-o-wars move?
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
Swells dropped to 1–1.5 m on 28 June 2011, allowing more netting of sardines. Sardines were netted at Amanzimtoti; on the main beach and at Chain Rocks. A 22-year-old American marine biology student (research diver) named Paulo Edward Stanchi was attacked by a large dusky shark while diving at Aliwal Shoal Marine Protected Area. The group of divers had encountered a pocket of sardines when a 3 m long dusky shark bit Mr Stanchi on his left leg and hands. Mr Stanchi managed to free himself from the shark, and was treated on the diving boat before being transported to Rocky Bay, where medics stabilised him. He was then airlifted to Nkosi Albert Luthuli Hospital, where he underwent surgery. Dusky sharks generally live offshore, but come closer to the shore during the sardine run. The annual sardine run allowed more dusky sharks in the Aliwal Shoal MPA than usual, but there was no reason for them to show any more interest in divers than usual. Mr Stanchi had been wearing split fins with black and grey stripes, and this may have looked like a small shoal of fish to the shark. Meanwhile, a woman in her 40s broke her leg in the frenzy at Amanzimtoti when the sardines were netted. The woman is believed to have been trying to get some of the sardines when she "stepped wrong" and fractured her leg. Paramedics stabilized her before transporting her to hospital.
Steamship generally refers to larger steam-powered ships, usually ocean-going, capable of carrying a (ship's) boat. The engine room, to the right, is a concept drawing during the construction of the ship. The term steam wheeler is archaic and rarely used. In England, "steam packet", after its sailing predecessor, was the usual term; even "steam barge" could be used (Steam tonnage in Lloyd's Register exceeded sailing ships tonnage by 1865). The French transatlantic steamer was probably the last of her type to be equipped with sails, although she never used them. Steamships in turn were overtaken by diesel-driven ships in the second half of the 20th century. Most warships used steam propulsion from the 1860s until the late 20th century
Two styles of swords are worn by Marines. The Marine Corps officers' sword is a Mameluke Sword, similar to the Persian shamshir presented to Lt. Presley O'Bannon after the Battle of Derna during the First Barbary War. After its adoption in 1825 and initial distribution in 1826, Mameluke Swords have been worn by Marine officers ever since, except during the period 1859–1875, when they were required to wear the Army's Model 1850-foot officers' sword. Upon returning to the traditional sword, many officers gave their Army swords to their senior noncommissioned officer, creating the basis for the NCO sword. Generally, Marines are the only branch where enlisted members regularly carry a sword (the Army authorizes platoon and first sergeants to carry a Model 1840 sword during some ceremonies, while the Chief of Naval Operations authorized Chief Petty Officers and above to carry an optional ceremonial cutlass with dress uniforms in 2010).
Atlantic wolffish use their strong jaws to eat hardshell molluscs, crustaceans, and echinoderms. They do not eat other fish. They are known to frequently eat large whelks ("Buccinum"), cockles ("Polynices", "Chrysodomus" and "Sipho"), sea clams ("Mactra"), large hermit crabs, starfish, sea urchins. They are an important predator of sea urchins and green crabs, whose populations escalate rapidly and can negatively affect the health of a marine system.
Man o' War next entered the Potomac Handicap at Havre de Grace Racetrack in Maryland on September 18. Man o' War was assigned 138 pounds, conceding from 24 to 34 pounds to his rivals, which included Kentucky Derby winner Paul Jones. Man o' War faced an early challenge from Blazes then turned back a late run by Wildair to win by lengths while breaking the track record by seconds. Although Man o' War was not seriously challenged, the high weight and a poorly maintained racing surface took a toll: Man o' War came out of the race with a swollen tendon on his right foreleg.
The final start of Man o' War's career came in Windsor, Ontario, Canada, in the Kenilworth Park Gold Cup on October 11. The event was so highly anticipated that it became the first horserace to be filmed in its entirety, with the resulting footage later shown in movie theaters across the country. The race was originally intended to be a face off between the three great horses of the time: Man o' War, Sir Barton and Exterminator. However, the owners of Sir Barton and Man o' War agreed to a distance of miles, which was too short for Exterminator to run his best, and agreed to a weight-for-age format, under which the older Exterminator would concede weight to Man o' War. Therefore, Exterminator was not entered, and in fact raced that same day on a different track.
Riddle contemplated entering Man o' War against older horses for the first time in the $5,000 Saratoga Gold Cup, but ultimately chose to enter the $15,000 Lawrence Realization Stakes against three-year-olds instead. When his only rival scratched from the race, it nearly became a walkover until Mrs. Riddle's niece, Sarah Jeffords, entered Hoodwink. To compensate for the lack of competition, Riddle announced that Man o' War would be allowed to show his speed. Man o' War was reunited with regular jockey Kummer, after being ridden by Sande and Schuttinger while Kummer recovered from an injury. Kummer neither restrained the horse nor urged him on at any point in the race. Running as he pleased, Man o' War won by slightly more than a quarter mile – the official margin was 100 lengths – while setting a new world record of 2:40 4/5 for a mile and five-eighths. This broke the existing world record set in England by seconds and lowered the American record by over four seconds. This world record stood until 1956, when it was broken by Man o' War's great-grandson Swaps.
Longships for the most part used two different kinds of anchors. The most common was a natural wood yoke formed from a tree branch. The weight was supplied by a stone passing laterally through the U of the yoke. The top of the yoke was closed by either a length of hardwood or a curved iron head, which kept the stone in place. One side of the head stuck out so it could dig into mud or sand. In the Ladby ship burial in Denmark, a unique iron anchor has been found, resembling the modern fisherman's anchor but without the crossbar. The cross bar may have rusted away. This anchor—made of Norwegian iron—has a long iron chain to which the hemp warp was attached. This construction has several advantages when anchored in deep waters or in rough seas.
The crew attempted to drop the starboard anchor, but it did not catch in the stony ground. "Gneisenau" was driven into the mole repeatedly, striking it with her stern twice before being turned and pushed bow-first on the starboard side, forcing her aground. A merchant ship attempted to come to the crew's aid, but they were unable to connect a line between the two ships before "Gneisenau" began to list 35 degrees. A boat from shore also attempted to rescue the crew, but it too was forced ashore in the heavy seas. Wave action quickly smashed "Gneisenau"s hull against the mole, and part of her crew attempted to find safety by climbing the rigging. The ship rolled over onto her side, and the surviving crewmen reached shore with a line. Forty-one men were killed in the accident, including Kretschmann and the ship's first officer. "Charlotte" and the British ironclad were sent to aid the wounded. Those killed in the sinking were buried in Málaga's cemetery, and the survivors returned to Germany aboard the HAPAG steamship on 2 January 1901.
Two submarines of the United States Navy have been named Cuttlefish for the cuttlefish, a ten-armed marine mollusk similar to the squid.
The "Elizabeth II" is a full-size representative 16th-century sailing ship that was designed and named after one of the seven ships used by Sir Walter Raleigh's fleet when he first brought colonists to Roanoke Island in 1587. The ship is a square-rigged bark with three masts, and 69 feet long, 17 feet wide and draws 8 feet of water. Guides dressed in period clothing portray the seamen and colonists who traveled to Roanoke with the fleet.
She also had six masts (said to be named after the days of a week – Monday being the fore mast and Saturday the spanker mast), providing space for of sails (7 gaff and max. 9 (usually 4) square sails), rigged similar to a topsail schooner with a main gaff sail (fore-and-aft sail) on each mast, one "jib" on the fore mast and three square sails on masts no. 2 and no. 3 (Tuesday & Wednesday); for a time mast no. 4 was also fitted with three yards. In later years, some of the yards were removed. According to some sources she would have carried . This amount of canvas is obviously too much for seven fore-and-aft sails and max. 9 square sails. This (larger) figure of sail area lies only a few square metres below that the famous Flying P-Liner "Preußen" carried – with her five full-rigged masts of 30 square sails and a lot of stay sails. Setting sails turned out to be unusable at the same time as the paddles and screw were under steam, because the hot exhaust from the five (later four) funnels would set them on fire. Her maximum speed was 24 km/h (13 knots).
The American oystercatcher feeds almost exclusively on shellfish and other marine invertebrates. Oysters are a staple of their diet, as their name suggests, but they also eat mussels, clams, limpets, sea urchins, starfish, crabs, and worms. In general, they use their bills to catch shellfish. As they walk across a shellfish bed, they look for a mollusk with a partially opened shell. When they find one, they jab their bill into the shell and sever the muscle that causes the shell to clamp shut. This can be dangerous, however, as they are sometimes drowned when they don't completely severe this muscle and the shell clamps down on their bill. A strong, tightly rooted mollusk can hold the bird in place until the tide comes in. They also feed by carrying loose shellfish out of the water and hammering at the shell or by probing the sand for soft-shell or razor clams.
Sea urchins or urchins () are typically spiny, globular animals, echinoderms in the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to . Their tests (hard shells) are round and spiny, typically from across. Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include sea otters, starfish, wolf eels, and triggerfish.
The archaeology of shipwrecks can be divided into a three-tier hierarchy, of which the first tier considers the wrecking process itself: how does a ship break up, how does a ship sink to the bottom, and how do the remains of the ship, cargo and the surrounding environment evolve over time? The second tier studies the ship as a machine, both in itself and in a military or economic system. The third tier consists of the archaeology of maritime cultures, in which nautical technology, naval warfare, trade and shipboard societies are studied. Some consider this to be the most important tier. Ships and boats are not necessarily wrecked: some are deliberately abandoned, scuttled or beached. Many such abandoned vessels have been extensively salvaged.
SS "Manhattan" was an oil tanker constructed at the Fore River Shipyard in Quincy, Massachusetts that became the first commercial ship to cross the Northwest Passage in 1969. Having been built as an ordinary tanker in 1962, she was refitted for this voyage with an icebreaker bow in 1968–69. Registered in the United States at the time, she was the largest US merchant vessel as well as the biggest icebreaker in history.
Ice and his gang of sharks decide to let an iceberg sink the "Titanic". They fool an octopus named Tentacles into heaving an iceberg to the surface of the ocean by concealing the plan in the form of a bet to see who can throw ice the farthest. Onboard the "Titanic", the Duke is forced to sign the whaling concession at gunpoint, after which Maltravers and his entourage flee the ship in a lifeboat.
The victory confirmed the naval supremacy Britain had established during the course of the eighteenth century and it was achieved in part through Nelson's departure from the prevailing naval tactical orthodoxy of the day. Conventional practice at the time was for opposing fleets to engage each other in single parallel lines, in order to facilitate signalling and disengagement, and to maximise fields of fire and target areas. Nelson instead arranged his ships into two columns to sail perpendicularly into the enemy fleet's line.
A fast craft is a vessel capable of speeds over 30 knots. HSICs (High Speed Interceptor Craft) however, trump fast craft with speeds of over 50 knots. HSICs are usually either custom or law enforcement craft. Law enforcement use these extremely fast boats to catch criminals such as smugglers or drug traffickers who use fast craft as well. The military have started to use HSICs to stop international threats such as pirates, militias, terrorists and weapons traffickers. Originally HSICs were not meant to carry large weapons. Now that the military is using them, they are being built with heavy machine guns. The boats have to be fitted with robust weight control and at the same time have heavy amour. HSICs must do without propellers to account for cavitation and vibrations. Instead HSICs use surface drivers or water jets.
As a result of the Battle for Anholt, the Royal Marines won many supporters among senior naval officers, which helped to further their cause for fairness in terms of service and officers' promotion. It was customary for senior officers to be presented with ceremonial swords, to commemorate significant victories. As well as Captain Maurice receiving a sword, Captain Torrens received two swords, one from his brother officers, and another from the non-commissioned officers and privates. This latter sword was purchased by the Royal Marines Museum, on the 200th anniversary of the battle of Anholt, and all three are on display at the Royal Marines Museum.
In the 2010 video game "Nine Hours, Nine Persons, Nine Doors", the main characters were all put onto a sinking ship by a mysterious person named Zero. In their introduction, Zero references the "Titanic"s sinking in the line "On April 14, 1912... the famous ocean liner "Titanic" crashed into an iceberg. After remaining afloat for 2 hours and 40 minutes, it sank beneath the waters of the North Atlantic. I will give you more time. 9 hours is the amount of time you will be given to escape." It is later discovered that the "ship" they are on is a replica of one of "Titanic"s sister ships, the Gigantic. In real life, "Gigantic" was rumored to have been the original name of the HMHS "Britannic", which was one of the "Titanic"s sister ships.
David Uckotter, who was the engineering director for the Lexington-Fayette Urban County Government during the road's construction, also noted that Man o' War had to be designed and built around numerous subdivisions that were sprouting throughout south Lexington in that era. He indicated that this dictated a 120-foot right-of-way, which left no room for breakdown lanes. Uckotter also added that at the time Man o' War was proposed, plans were on the table for a southern beltway similar to New Circle Road outside Man o' War, hugging the border between Lexington and Jessamine County. These plans were dropped in the early 1980s, leaving Man o' War as Lexington's only circumferential road outside New Circle, which Uckotter contends has contributed to current problems with Man o' War.
Man o' War made his debut at Belmont Park on June 6, 1919 in a maiden race over five furlongs. At the time, horses had to race clockwise at Belmont Park rather than counter-clockwise like all the other American tracks of the day, so horses had to learn to race in both directions. This practice ended in 1922 after Man o' War retired. Man o' War won his first race by six lengths, then just three days later was entered in the Keene Memorial Stakes at a distance of furlongs on a muddy track at Belmont Park. At this point in his career, Man o' War had not yet learned how to start quickly but soon settled into fourth place. With an eighth of a mile remaining, jockey Johnny Loftus urged Man o' War to run and the horse responded by pulling away from his rivals to win by three lengths. Twelve days later, Man o' War followed up with another win in the Youthful Stakes at Jamaica Race Course. Two days after that, he swept to victory in the Hudson Stakes at Aqueduct to record his fourth win in just 18 days. Less than two weeks later, he returned to win the Tremont Stakes at Aqueduct on July 5.
Scotty Baesler, who was mayor of Lexington during most of the construction phase, argued in a 2007 interview with the city's daily newspaper, the "Lexington Herald-Leader", that much of this criticism was either unfair or the result of misconceptions. For example, he pointed out that Man o' War was not designed as a limited access freeway like the city's inner beltway, New Circle Road, a highway to which many unfavorably compare Man o' War—it was intended as an urban arterial. He also added,
The idea of an outer southern bypass of Lexington first appeared in Lexington city plans in the 1930s as Tiverton Way. However, construction did
not begin on the road until 1973. The following year, the road was renamed Man o' War Boulevard. The first stretch of Man o' War, between Richmond Road (US 25) and Palumbo Drive, opened as a two-lane road in 1975. In 1979, the highway was completed between Mount Tabor Road, now known as Alumni Drive, and Armstrong Mill Road. By November 1983, it was completed to Tates Creek Road and extended to Nicholasville Road one year later. In January 1985, Man o' War had been extended to Bold Bidder Drive and work was beginning on a segment to extend the road to Todds Road.
