Coast Pilot 7 Flashcards
The Coast Pilot 7 is intended to be used as a supplement to what?
Supplements NOAA Nautical Charts
Coast Pilot 7 chapters 1 thru 3 - give a brief description of what each chapter covers.
Chapter 1 - general information/definitions and standards
Chapter 2 - Navigation regulations - CFRs (code of federal regulations)
Chapter 3 - information that is specific to that region of the coast pilot. Coast Pilot 7 is California
According the Coast Pilot 7, what range of scale to NOAA charts come in?
1 : 2,500 to 1 : 5,000,000
Coast Pilot 7 classifies the charts into 5 categories in terms of chart size. You have Sailing charts, general charts, coast charts, harbor charts and special charts. What are their respective sizes?
Sailing charts : 1 : 600,000 and smaller
General charts : 1: 150,000 thru 1: 600,000
Coastal charts : 1 : 50,000 thru 1 : 150,000
Harbor charts : 1 : 50,000 and larger
Special charts : various sizes, cover ICW and various small craft areas
The type of Charts that are used for nautical charts which have straight-line meridians and parallels that intersect at right angles are know what ___________ charts.
Mercator projection charts
EPIRBS : frequency of broadcasting is 406 MHz, there are 2 categories, Cat I and Cat II. Tell me the differences.
Cat I : basically is hands off, automatically actives when in the water.
Cat II : main difference is that it requires manual activation
NOAA weather radio broadcasts operate 24hrs a day and have a range about 40 miles from the antenna. The messages on these station are repeated every ____ to ____ minutes and are normally revised every _____ to _______ hours
4 to 6 minutes
1 to 3 hours
True or False : Navigation Rules, International-Inland, Rule 9(b) states that a vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel that can safely navigate only within a narrow channel or fairway
True
National weather service Coastal warning displays : they are shown in day time signals and night light signals. The day signals are shown with flags, the night signals with lights. How are the following shown for day time signals?
Small craft advisory
Gale warning
Storm warning
Hurricane warning
Small craft advisory = single RED pennant flag
Gale warning = 2 RED pennant flags in vertical line
Storm warning = single RED square flag with small black square in the middle
Hurricane Warning = 2 RED square flags with small black square in the middle, one flag above the other in a vertical line.
National weather service Coastal warning displays : they are shown in day time signals and night light signals. The day signals are shown with flags, the night signals with lights. How are the following shown for night times signals?
Small craft advisory
Gale warning
Storm warning
Hurricane warning
Small craft advisory = RED light above WHITE light in vertical line, RED WHITE
Gale warning = WHITE light above RED light in vertical line WHITE RED
Storm Warning = 2 RED lights in vertical line RED RED
Hurricane warning = 3 lights in vertical line RED, WHITE, RED
To help remember = RED WHITE RED : red (small craft) white (gale) red (Storm)
What is the range of wind that will trigger all of these potential warning?
Small Craft Advisory
Gale Warning
Storm Warning
Hurricane warning
Small Craft = 21 thru 33 knots potentially in combination of waves exceeding 10 feet
** tricky one - this is for WEST COAST different zones have different ranges
Gale Warning = 34 thru 47 knots
Storm Warning = 48 knots and above no matter how high winds reach it will be a storm warning. UNLESS the high winds are from a hurricane . If from a Hurricane then the range will be from
48 thru 63 knots.
Hurricane Warning = 64 knots and above (only issued if associated with an actual hurricane) otherwise it will be classified as a Storm Warning even if above 64 knots.
Coast Pilot 7 states that Santa Ana winds occur where? Also they can reach in excess of ______knots and travel ______ miles out to sea.
Santa Ana winds occur near or in San Pedro bay
50 knots
50 miles out to sea
According to Coast Pilot 7 chapter 4 : best marine practices, while at anchor in the LA/LB harbor areas, if the wind exceeds ______ knots have power plant on standby
40 knots - for all vessels 1600 tons or more
This is different than the Harbor Safety plan which states 35 knots. The safety plan does not give a weigh, only a wind speed of 35 knots
According to Coast Pilot 7 chapter 4 : best marine practices, while at anchor in the LA/LB harbor areas, before weighing anchor, give _____ minutes notice VTS.
15 minute notice before leaving anchorage
According to the Coast Pilot 7 where can accurate wind speed to determined while at anchor in the Port?
By contacting either VTS or the appropriate pilot station
All anchorages outside the federal breakwall are managed and monitored by who?
VTS - vessel tracking system
Bonus : if desiring to anchor you must advise VTS on Ch 14 and get their clearance
Anchoring inside the federal breakwater requires at least 1 tug for assistance if the vessel is over what draft?
15.2 meters
Between Los Angeles Approach Channel Lighted Buoy 1 and Los Angeles Main Channel Lighted Buoy 11, minimum under-keel clearance before correction for roll and pitch is _______percent of vessel’s draft
10 percent
In the channel between Los Angeles Main Channel Lighted Buoy 11 and a position off the designated berth, minimum under-keel clearance is _______ feet
2 feet
Shifts via outer harbor between Los Angeles and Long Beach, minimum under-keel clearance ______feet
3 feet
Port of LB : At anchorages inside the breakwater, minimum under-keel clearance is ______feet for Anchorages B-7 and B-11 when vessels draft is 50 feet or more and ________feet for all other anchorages.
4 feet
2.5 feet
Inclement weather : High winds are defined once the National Weather Service issues a small craft advisory for sustained winds of _____ to ______knots, potentially in combination with wave heights exceeding _______feet
Small craft advisory : 21 to 33 knots
10 feet
No question on this, just read it and have some understanding:
Restricted visibility is defined once conditions of visibility fall below the following:
• For tankers 150,000 DWT or greater: 1 nautical mile
• For tankers greater than 60,000 DWT, but less than 150,000 DWT: 0.75 nautical mile
• For all other vessels 45-foot draft or more: 0.75 nautical mile
• For all other tankers and petroleum barges: 0.5 nautical mile
• For all other vessels: Three (3) times vessel’s LOA
No answers, just read the question and have an understanding of what the Coast Pilot 7 says for restricted visibility
When visibility inside the federal breakwater is less than 0.5 mile, the respective vessel traffic center (VTC) will impose what kind of traffic restrictions?
one-way traffic restrictions when and where appropriate
Los Angeles Light aka Angels Gate Light : tell me focal height, range and characteristics and horn
73 feet - white cylindrical tower with black vertical stripes
14 miles
Fl G 15s
Horn = 2 blasts every 30 sec
