MACKINAW USCGC icebreaker-buoy-tender

Built as a icebreaker-buoy-tender under yard no 601 by Marinette Marine Corporation (MMC), Marinette, USA for the USA Coastguard.

Laid down: February 09, 2004.
Launched: April 2, 2005 under the name USCGC MACKINAW (WLBB-30), the name Mackinaw has its roots in the ancient Native American language of the Great Lakes. Specifically, it is derived from the word Michilimackinac in the Ojibwa language, meaning "Island of the Great Turtle." Both Mackinaw (the English derivation) and Mackinac (the French derivation where "ac" is pronounced "aw") are derived from this word and pronounced Mak'ino.
Displacement 3,500 ton, dim. 73 x 17.8 x 4.9m. (draught), length bpp. 69.9m.
The ship is powered by 3 Caterpillar Turbocharged V-12 engines that drive 2 ABB electric propulsion drives that deliver a combined 9,200 horsepower. They are Caterpillar 3612 engines, turning Kato Generators. Mackinaw has 3 MDG’s. Each producing about 3.5 Megawatts of electric power. Mackinaw has an integrated electric plant. This means that the main generators provide electric power for both propulsion (ABB Azipods) and ship’s electric services (everything else). Speed 16 knots.
Crew 9 officers and 46 enlisted.
Commissioned: June 10, 2006, Homeport: Cheboygan, Michigan IMO No 9271054.

WLBB: The W preceding the number of all Coast Guard ships since World War II signifies them as Coast Guard vessels. WLB is the Coast Guard’s designation for seagoing buoy-tenders. The L stands for load-bearing working boat, and the B specifies its size category (big). The LB designates this vessel as a big buoy-tender, and the last B stands for icebreaker.

USCGC MACKINAW (WLBB-30) is a 240-foot (73 m) vessel built as a heavy icebreaker for operations on the North American Great Lakes for the United States Coast Guard. IMO number: 9271054. She should not be confused with a namesake ship, the USCGC MACKINAW (WAGB-83), IMO number 6119534, which was decommissioned on June 10, 2006.
MACKINAW was delivered to the Coast Guard on November 18, 2005 and commissioned on June 10, 2006. In addition to her ice-breaking duties, the MACKINAW will also serve as an Aids to Navigation ship, able to perform the same duties as the Seagoing Buoy Tenders (WLB) of the Coast Guard fleet. Further, she can conduct law enforcement and search and rescue missions and can deploy an oil skimming system to respond to oil spill situations and environmental response. One of the MACKINAW's unique features in the US Coast Guard fleet is the use of two Azipod units, ABB's brand of electric azimuth thrusters, for her main propulsion. These, coupled with a 550 hp (410 kW) bow thruster, make the ship exceptionally maneuverable. The Azipod units also remove the need for a traditional rudder, as the thrusters can turn 360 degrees around their vertical axis to direct their thrust in any direction. The MACKINAW also lacks a traditional ship's steering wheel. Much of the ship’s technology, including the Azipod thrusters, is from Finnish Maritime Cluster. Additionally, the MACKINAW can continuously proceed through fresh water ice up to 32 inches (81 cm) thick at 3 knots or 14 inches (36 cm) at 10 knots. She can also break smooth, continuous ice up to 42 inches (107 cm) thick through ramming.

The MACKINAW got off to a rocky start before being commissioned. While en-route to her new home port of Cheboygan, Michigan, the MACKINAW struck a seawall in Grand Haven, Michigan on December 12, 2005. The accident caused a 10-foot (3.0 m) dent in the bow of the MACKINAW on her starboard side. Shortly after the accident, Captain Donald Triner, the commanding officer of the MACKINAW, was temporarily relieved of duty pending an investigation into the accident. The accident did not delay the ship's scheduled arrival in her new home port; she arrived on December 17, 2005. Captain Triner was later permanently relieved of duty and replaced by Captain Michael Hudson, who was replaced in turn by Commander John Little in April 2006. CDR Scott J. Smith assumed command in July 2008 and was relieved by CDR Michael J. Davanzo in Aug, 2011. In June 2014, CDR Vasilios Tasikas assumed command. In June 2017, CDR John Stone assumed command. The MACKINAW is stationed at Cheboygan, Michigan. It can be seen and toured at Grand Haven's Coast Guard Festival every summer. The ship was also featured on the television series Modern Marvels. Katmai Bay, stationed at Sault Ste. Marie, Michigan, helps the USCGC MACKINAW (WLBB-30) in ice breaking duties.
2019 In service.

In the margin you see a freefall lifeboat and a helicopter picking up survivors. I have been sailing on ships fitted with a freefall lifeboat and in my eyes she are the best system for a lifeboat to get safely and very quickly of a vessel.

Wikipedia gives for the freefall lifeboat:
Some ships have a freefall lifeboat stored on a downward sloping slipway normally on the stern of the vessel. These freefall lifeboats drop into the water when the holdback is released. Such lifeboats are considerably heavier as they are strongly constructed to survive the impact with water. Freefall lifeboats are used for their capability to launch nearly instantly, and high reliability in any conditions. Since 2006 they have been required on bulk carriers that are in danger of sinking too rapidly for conventional lifeboats to be released. Seagoing oil rigs are also customarily equipped with this type of lifeboat.

Afanasy Nikitin (Russian: Афана́сий Ники́тин; died 1472) was a Russian merchant of Tver and one of the first Europeans (after Niccolò de' Conti) to travel to and document his visit to India. He described his trip in a narrative known as The Journey Beyond Three Seas (Khozheniye za tri morya). In 1466, Nikitin left his hometown of Tver on a commercial trip to India. He travelled down the Volga River, and although he was attacked and robbed by Tatars near Astrakhan he succeeded in reaching Derbent, where he joined Vasili Papin, the envoy of Ivan the Great to the shah of Shirvan. At Derbent, Nikitin vainly endeavoured to get means of returning to Russia; failing in this, he went on to Baku and later Persia proper by crossing the Caspian Sea He lived in Persia for one year. In the spring of 1469, Nikitin arrived at the city of Ormus and then, crossing the Arabian Sea, and making several prolonged stays along the way, reached the sultanate of Bahmani, where he would live for three years. From what he tells us, he appears to have made his living by horse-dealing. During that ime he visited the Hindu sanctuary of Perwattum, which he called "the Jerusalem of the Hindus". On his way back, Nikitin visited Muscat, the Arabian sultanate of Fartak, Somalia and Trabzon, and in 1472 arrived at Feodosiya by crossing the Black Sea. On his way to Tver, Nikitin died not far from Smolensk in the autumn of that year. During his trip, Nikitin studied the population of India, its social system, government, military (he witnessed war-games featuring war elephants), its economy, religion, lifestyles, and natural resources. The abundance and trustworthiness of Nikitin's factual material provide a valuable source of information about India at that time, and his remarks on the trade of Hormuz, Cambay, Calicut, Dabhol, Ceylon, Pegu and China; on royal progressesand other functions, both ecclesiastical and civil, at Bahmani.,and on the wonders of the great fair at Perwattum—as well as his comparisons of things Russian and Indian—deserve special notice. A few years after his death his unique writings were transferred to Moscow where they were saved and rewritten. In 1955, in the city of Tver, the homeland of Afanasy Nikitin, a monument was erected to commemorate him.
