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.

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.

About 200th anniversary of the birth of Cosme García Sáez

With the issuance of this seal, Spanish Correos intends to pay a well-deserved tribute to Rioja Cosme García Sáez, one of the many forgotten geniuses of our country. Born in Logroño on September 27, 1818, in the bosom of a humble family. Restless and self-taught, from a very young age he showed a great facility for mechanics and technical studies, which he would shape years later in the creation of inventions related to weapons, printing, mail and nautical.
He moved to Madrid at the beginning of the Progressive Biennium and two years later, in 1856, he presented his first three inventions: a back-loading rifle, a portable printing press and a device "for all kinds of ink stamps". The latter was adopted by the Post Office in 1857 to mark, on the front of the letters, the date of issue and, on the reverse side, the date of arrival, hence its name: date 1857 or Type II, replacing the 1854 model o Type I. The steel stamp of great quality and manufactured abroad, left an imprint formed by two concentric circles of 19.5 and 11 millimeters in diameter. In the center appears the data, with expression of the day, the first three letters of the month inclined to the left and the last two figures of the year. In the upper part of the circular crown the name of the town and in the lower the capital of the respective province; when it is a main Administration, its hierarchical number appears in the lower part. This type of dater was used until the late 1870s.
The capital obtained from the sale of some 600 dating machines and the maintenance of the same between 1857 and 1861, served Cosme García to continue in his career as an inventor. During his visit to the main Administration of Barcelona he discovered the sea for the first time and immediately began to develop his most famous patent: the submarine. The tests of his first model were made in the waters of Barcelona in 1858, one year before the ICTINEO of Narciso Monturiol.

As it could not be less, Correos innovates in the stamp dedicated to an inventor; the paper is replaced by rubber and the motif appears in relief: the silhouette of Cosme García, the sketch of the submarine under the waves, the legend and the imprint of the 1857 dashboard, which protrudes from the right side of the effect.


Cosme Garcia Sáez ordered by the workshop La Maquinista Terrestre y Marítima in Ciudad Condal a prototype of his first submarine after his plans in 1858, after she was launched she made some trials which were unsatisfactory he improved the design and built a second one with an iron hull by the same workshop of La Maquinista.
He named his submarine the GARCIBUZO a name which joints part of his surname with “buzo” which means “diver”.
After several trials in Barcelona, he moved to Alicante where the submarine underwent her official trial a year later.

Dim. 5.75 meters long, 1.75 wide and 2.25 meters high, and had a shape very similar to that of current submarines and bathyscaphe. Powered by a spring mechanism (ie, a rope as the clocks), had rudders and ballast systems that allowed advance, submerge and ascend at will with great stability. Given the success achieved, Cosme Garcia contacted all the military authorities and invited them to the test that would be held at the Port of Alicante on August 4, 1860
Powered by hand by a crew of two men.
Before a large number of observers -among them military, politicians and consuls from different countries- who witnessed the event, the submarine was for 45 minutes submerged in the waters of the Alicante port, going up and down to the surface so that the people will not worry about the status of the sub. The incredible military possibilities and the cheers of the people once finished the "performance", was an absolute success of the submarine.
After the trial Cosme Garcia went to Queen Elizabeth II Queen of Spain called Paquita, to give him her blessing ... and finance a submarine made of copper.
But the economic position of the Spanish Government prevented the purchase of the submarine.
In view of the little - to say something - interest in his invention, he decided to present the project to Paris, where after patenting it in 1861 , he hoped that Napoleon III would have more desire and better vision of the future. And, indeed, it was.

Napoleón III offered a contract of 14 million francs to Cosme García, who would have to move to Toulon - French Riviera - to develop the craft. However, the patriotism of Cosme García, who still considered that his GARCIBUZO would be a weapon that would help the defense of Spain, made him at the last moment to decline the Gallic offer and, finally, his submarine was forgotten at the bottom of the drawer of the patent office.

Cosme Garcia ruined and in the most absolute misery, died in Madrid in 1874 plunged into a great depression because he could not have seen his work recognized by his country. An outrageous new twist occurred in 1898 when, war broke out between America and Spain over Cuba, the son of Cosme García offered his father's invention to the Spanish government, and this, in an act of supine blindness, ruled that it was not of interest since it could hardly be used.

The GARCIBUZO , which had remained moored in the port of Alicante since its test in 1860, was finally sunk by his son in an indeterminate place in Alicante port, before the notification he received from the port authorities of Alicante, according to which the submarine bothered the port activity. Sad end to one of the most decisive inventions in the next century and that, stubbornly and repeatedly would be despised by the ignorant cerrilidad of a corrupt government, more concerned to maintain their own privileges than to develop with a vision of the future the country that, supposedly, it had to administer. ... ciado.html
