Zulu Time Zone

Time zone offset: UTC
Z is in the same time zone as Coordinated Universal Time (UTC)
Time zone abbreviation: Z
Full name is Zulu Time Zone

Military & Civilian Time Designations
From Time Zone A - Z

There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.

Each Time Zone is measured relative to Greenwich, England. There are both civilian designations which are typically three letter abbreviations (e.g. EST) for most time zones. In addition there are military designations. These use each letter of the alphabet (except 'J') and are known by their phonetic equivalent. E.G. Greenwich Mean Time (civilian) or Z = Zulu (military and aviation).

NOTE: Greenwich Mean Time (GMT) is the same all year around
There is no Summer Time / Daylight Savings Time

Winter - Eastern Standard Time (EST) = GMT-5
Summer - Eastern Daylight Time (EDT) = GMT-4

Superior WI = Central Time ... Michigan = Eastern Time
Michigan is in the Eastern Time Zone in the United States of America (USA). Eastern Standard Time (EST) is 5 hours behind Greenwich Mean Time (GMT-5).Winter Only.
The United States spans 6 time zones. It shares the main four time zones with Canada (Eastern Time, Central Time, Mountain Time and Pacific Time).

UTC uses a 24-hour system of time notation. "1:00 a.m." in UTC is expressed as 0100, pronounced "zero one hundred." Fifteen minutes after 0100 is expressed as 0115; thirty-eight minutes after 0100 is 0138 (usually pronounced "zero one thirty-eight"). The time one minute after 0159 is 0200. The time one minute after 1259 is 1300 (pronounced "thirteen hundred"). This continues until 2359. One minute later is 0000 ("zero hundred"), and the start of a new UTC day.
Coordinated Universal Time (UTC)
International Telecommunication Union

Beginning in the 1920s, nautical time zones were referred to with alphabetic characters. The Z zone is equivalent to Coordinated Universal time (UTC), which is the time at the prime or "zero" meridian (0° longitude). The phonetic alphabet refers to Z as "Zulu". It is still used some settings (i.e. military, nautical and aviation) to refer to UTC.

99 r.p.m. = 16.3 mph

Fitzgerald
1 Statute Mile @ 16.3 Statute Miles per Hour = 3 Minutes and 40 Seconds
1 Statute Mile @ 16.2 Statute Miles per Hour = 3 Minutes and 42 Seconds
1 Statute Mile @ 16.1 Statute Miles per Hour = 3 Minutes and 43 Seconds
1 Statute Mile @ 16.0 Statute Miles per Hour = 3 Minutes and 45 Seconds

Anderson
1 Statute Mile @ 14.0 Statute Miles per Hour = 4 Minutes and 17 Seconds
1 Statute Mile @ 14.1 Statute Miles per Hour = 4 Minutes and 15 Seconds
1 Statute Mile @ 14.2 Statute Miles per Hour = 4 Minutes and 13 Seconds
1 Statute Mile @ 14.3 Statute Miles per Hour = 4 Minutes and 11 Seconds
1 Statute Mile @ 14.6 Statute Miles per Hour = 4 Minutes and 06 Seconds

Note: The Fitz was 26 Seconds faster per mile than the Anderson.
(Fitz gain 8976 Feet each hour)
Note One Mile = 5280 Feet

Anderson @ 14.6 mph = 1284.8 Feet per minute
Fitzgerald @ 16.3 mph = 1434.399 Feet per minute
The Fitz will travel 149.599 Feet per minute faster

Up and down boat action in larger waves over the shoals
A vessel may not exhibit this phenomenon in deep water but may show springing when passing over a shoal where the entrained water causes the virtual displacement of the hull to increase.
Feet the Fitz will travel forward @ 16.3 mph over a shoal and hit the bottom.

Cycles time per minute
60 Seconds = 1424.399
50 Seconds = 1195.333
40 Seconds = 956.266
30 Seconds = 717.199
20 Seconds = 478.133

8.5 Seconds = 203.206 Feet Travel (Time cycles per minute) Pitch - Roll - Yaw

Rotation around the front-to-back axis is called roll.
Rotation around the side-to-side axis is called pitch.
Rotation around the vertical axis is called yaw.

The Fitz broke at two areas, the missing center section would be 200 ft long.
The Fitz would have a 8.5 Seconds cycles per minute @ 16.3 mph near a shoal.

By the afternoon of the 10th, the Fitzgerald had reached the eastern part of the lake and the Witch of November had been punishing her and the Anderson for 14 hours. At 3:15 p.m., Captain Cooper and the Anderson's First Mate Morgan E. Clark watched the Fitzgerald on their radar as she crossed into dangerous water.

COOPER: "Look at this, Morgan. That's the Fitzgerald; he's in close to that six fathom spot."
CLARK: "He sure looks like he's in the shoal area.²
COOPER: "He sure does. He's in too close. He's closer than I'd want this ship to be."
At six feet to the fathom, Six Fathom Shoals is only 36 feet deep-- dangerous ground for such a big ship in a storm. Shallow water causes wave height to increase dramatically, and a big, heavy freighter like the Fitzgerald can strike bottom in the troughs of big waves.
At 3:30 p.m., Captain McSorley radioed the Anderson:
FITZGERALD: "Anderson, this is the Fitzgerald. I have sustained topside damage. I have a fence rail down, two vents lost or damaged, and a list. Will you stay by me 'til I get to Whitefish?"
ANDERSON: Charlie on that Fitzgerald. Do you have your pumps going?"
FITZGERALD: "Yes, both of them."
Investigators later determined the list was from taking on water either through damaged vents or from striking bottom.
Then, at 4:00 p.m., the Witch unleashed a screaming 87 knot (100 m.p.h.) wind gust on the Anderson-- a gust that continued straight toward the Fitzgerald. Ten minutes later Captain McSorley again radioed the Anderson:
FITZGERALD: "Anderson, this is the Fitzgerald. I have lost both radar's. Can you provide me with radar plots 'til we reach Whitefish Bay?"
ANDERSON: "Charlie on that, Fitzgerald. We'll keep you advised of your position."
