Takeaways
- 📚 The IALA stands for International Association of Maritime aids to Navigation and Lighthouse Authorities, which is an important organization in maritime navigation.
- 🌐 The script discusses the different types of buoys and their significance in maritime navigation, particularly for those preparing for interviews or evaluations in the maritime industry.
- 🔍 The IALA system has two areas, A and B, with different buoyage systems where red buoys are on the left in area A and green on the right, and vice versa in area B.
- 🏖 The buoys have specific shapes and colors to indicate their purpose, such as conical pillars for red buoys and spherical shapes for green buoys, with yellow buoys having special marks like an 'X' on top.
- ⚓ Cardinal buoys are used to mark points of interest or dangers and have distinct shapes and flashes to indicate the direction to pass for safety.
- 🚨 Isolated danger buoys are crucial for recognizing potential hazards in open seas and are characterized by two white flashes and a black-red-black color scheme.
- 🛳 Preferred channel buoys help navigators choose the correct channel to follow when entering a port or harbor, with more green indicating the preferred channel on the port side in IALA A.
- 📍 Special marks, like the water mark buoy, are used to indicate the center line or the best point to pass under a fixed bridge, and are marked with red and white stripes.
- 🚧 Emergency wreck buoys are used to mark recent navigational hazards that have not yet been plotted on charts, featuring a yellow and blue striped buoy with an upright yellow cross on top.
- 💡 The script emphasizes the importance of understanding buoyage systems for maritime professionals, especially for those working in areas like AD knock or Aramco.
- 👨🏫 The video is intended to help viewers prepare for interviews by familiarizing them with the terminology and appearance of various buoys, rather than just memorizing their names.
Q & A
What does IALA stand for and what does it represent?
-IALA stands for International Association of Lighthouse Authorities. It represents the modern name, which is the International Association of Maritime aids to Navigation and Lighthouse Authorities.
What is the purpose of the video by Captain Yevgen?
-The purpose of the video is to prepare viewers for interviews or evaluations related to maritime navigation, specifically focusing on the identification and understanding of different types of buoys.
How does the color of buoys differ between IALA A and IALA B systems?
-In the IALA A system, the red buoy is on the left side of the channel and the green buoy is on the right when entering from open sea. In the IALA B system, it is the opposite, with the green buoy on the left and the red on the right.
What does the shape of a buoy indicate about its purpose?
-The shape of a buoy can indicate its purpose. For example, a conical pillar or spherical spar can indicate the presence of a lateral buoy, while a square shape on top of a buoy can signify a special mark buoy.
How are Cardinal buoys used to indicate the direction of safe navigation?
-Cardinal buoys use their color and the direction they point to indicate safe navigation. A black and yellow buoy points north, a yellow and black buoy points south, and a triangular black buoy points east or west.
What is the significance of the flashes on a buoy?
-The flashes on a buoy provide additional information about its purpose. For instance, Cardinal buoys have specific flash sequences to indicate their directional purpose, and isolated danger buoys have two white flashes to signal potential hazards.
What does a Preferred Channel buoy indicate and how should it be approached?
-A Preferred Channel buoy indicates the main or preferred route through a channel. When approaching, the vessel should pass on the side of the buoy that has more green markings to remain in the main channel.
How are isolated danger buoys marked and what do they signify?
-Isolated danger buoys are marked with two black and red vertical shapes (BRB) and two white flashes. They signify potential hazards or dangers in the water that vessels should avoid.
What is the role of a Special Mark buoy and what does it look like?
-A Special Mark buoy is used to indicate the limits of certain areas or to mark new dangers. It typically has a yellow color and may have an X shape on top.
How can the information from this video be applied during an interview or evaluation in the maritime industry?
-The information can be used to answer questions about buoy identification, navigational aids, and safe maritime practices during interviews or evaluations, particularly for job offers or positions related to maritime navigation.

📚 Introduction to Maritime Aids and Interview Preparation
Captain Yevgen introduces the video, focusing on maritime aids and preparing for interviews or evaluations in the maritime industry, particularly for job offers from companies like ADNOC or Aramco. He emphasizes that questions about maritime aids are common and usually require descriptive answers. The IALA (International Association of Maritime aids to Navigation and Lighthouse Authorities) is mentioned, and the video aims to provide a brief overview of various maritime aids, including buoys, to help viewers quickly prepare for such questions. The Captain also invites feedback on the content and mentions his working environment, hinting at the challenges of creating content under non-ideal conditions.
🚢 Understanding Buoy Systems and Navigational Markings
The second paragraph delves into the specifics of buoy systems, explaining the difference between the IALA A and IALA B systems used in various parts of the world. It discusses the color and positioning of buoys in channels, with red typically on the left and green on the right in IALA A, and the opposite in IALA B. The paragraph also covers special buoys with yellow markings, which indicate the limits of certain areas. Cardinal buoys and isolated danger buoys are introduced, with the former indicating the direction to pass safely around a danger and the latter warning of immediate danger. The importance of recognizing these buoys, especially in narrow channels or open seas, is highlighted.
🌐 Cardinal Buoys and Navigational Precautions
In this paragraph, the focus is on Cardinal buoys, which mark points of interest, shallow areas, or dangers. The buoys are described by their color patterns and shapes, with yellow and black markings indicating the direction to pass for safety. The paragraph explains how these buoys use flashes to communicate their purpose, with different numbers of flashes and intervals indicating the cardinal direction of the danger. The North Cardinal buoy is said to have a continuous flash, while the East and West have three and nine flashes respectively, and the South has six flashes with a long interval to avoid confusion in rough seas. The paragraph also touches on the use of buoys as reference points for safe navigation.
⚠️ Emergency Wreck Markings and Final Thoughts
The final paragraph discusses the use of special buoys for marking recent navigational hazards, such as newly discovered rocks or sunken vessels that have not yet been plotted on charts. These hazards are indicated by yellow and blue striped buoys with an upright yellow cross on top. The paragraph serves as a reminder of the importance of staying informed about navigational warnings and updates. The video concludes with an invitation for viewers to subscribe to the channel, share their experiences, and join the Estimar educational platform for further maritime knowledge.

Transcripts
quick reminder about yala Maritime Bush
system
hi guys Captain yevgen is here with you
and you are on estimar channel today we
will talk about the different boys and
we will not learn them but we will
prepare ourselves for the interview or
evaluation
these questions are commonly asked
during when you have interview for the
job offer or when you are like in the
area of AD knock or aramco and the
questions about the boys also can appear
and normally it is not like this like
okay what is this boy what is this boy
what is this boy yeah so normally
uh it is like okay describe me what is
the flesh how does it look like uh what
do you know and that's it so we will
just go briefly about the boys because
we are valuing our time and then I will
stop on normally
mistake answers which personally I
received when I asked about this voice
so you probably
see my screen I hope so I'm in my
working environment not home not in my
office and I do what I can and I hope
you will forgive me if some things
is wrong something goes wrong then
I do my best I do the content and
actually I appreciate if you write some
comment if this content is
good or what would you advise to improve
so most of you will find on most of
devices
NP 735 of admirality it's like quite
seeing book I don't have it just with me
maybe I will go on one of my vessels
next time I'll put an Instagram about
this uh
quite thin book and the iala stays for
International
Association of Lighthouse authorities if
you can see right here right
about the modern name now it's called
International
Association of Maritime aids to
navigation and Lighthouse authorities I
didn't face a difficulty or at least a
case when the person failed interviewer
evaluation if he could not answer what
does
Ayala States for but it's better to know
then a quick overview yeah we have
different areas yeah A and B yeah I will
minimize a bit
yeah
here we are so normally if you have kind
of evaluation and you have some certain
area like in the Gulf area here
you have IAL a which means red
light or whatever or Boy Color and
flashlight is on the left side of the
channel and the green is on the right
why I don't say port and starboard
because it's let's say referred when you
are entering the port entering the
harbor entering the channel from the
Open Sea the red should be on the left
the green should be on the right in ela
a and opposite in yellow B
so that the
somewhere in the area of North and South
America of Japan you can see here
it is opposite the green is on the left
side of the channel and the red is on
the right side of the channel
and we go furthermore
what we can see can conical pillar
spherical spar
yellow a as we discussed on the left we
have rate on the right we have green and
on the red we have on top some square
shape on the right a green a part of
this
red and green we have yellow special
marks they have the shape of X on top
might not have but they're of yellow
color they usually indicating
the limits of some areas and so on so
that you recognize that you are entering
or you are close to some area
we have Cardinal boys we'll go closer to
them we have this
pillars which still not many people can
answer what does it mean and we have
this isolated danger boy for example so
on this stage I would prefer to pay your
attention so it is usually when you have
evaluation or interview you don't have
picture yeah that's why I would be able
with pleasure to put here 3D graphics
and again
to describe all the boys from the
beginning but this is not the aim of
this video the aim of these videos when
you talk when you talk like I'm talking
to you you can name and and name the boy
and answer the question for example the
interviewer can be also different and
for example he's saying like this take
some torch in the in the hand and making
like this
what is this so you have you're hiding
on the vessel and right that the head of
Your Vessel you can see two flashes what
does it mean so we can go this way or uh
the same boy
uh can be asked differently okay
describe isolated danger boy why is that
important because well
normally if you are entering some narrow
channels there Captain is on the bridge
or you are the captain you can maybe
have pilot and so on but when you are an
open Siege can still be isolated danger
it's smart and you really
should know how to recognize it and what
uh to do how to act yeah on the chart
isolating danger is marked like this
there's a black red black BRB
so the same the the color of the
boy is also black red black on top two
vertical
shapes spherical
and you it's a tip how to remember
you have two shapes two flashes
yeah two shapes two flashes easy to
remember and then we unfortunately get
used to the situation when we have
something what is the stop item is
something like rat like a traffic light
on the signs on the road and we get used
red it's a no-go so people straight say
the two flashes of red light but then
what is uh lateral boy for it's also
that and clearly even even here if you
go I I don't remember if it is close to
here or not they describe a lateral boy
which can give different
um yeah here here we are
you see right here
two flashes even somebody you see um
put the line under underlined two
flashes red and this is clearly not
isolated danger so isolated danger is
two white flashes
so also here
[Music]
um
normally if somebody want just to check
if you really deep in knowledge they
will ask you them
boy of Preferred channel
preferred channels it means then when
you are entering I will go to the
picture above when you are entering
uh for example some neuros Channel and
you have like kind of
the the the root divides into two parts
yeah
so and you are probably first time in
this area and you have no idea to to
choose which one to to the to your left
or to your right to the port side to the
starboard side and then everybody is
confusing if we see this uh indication
of preferred Channel Boy where to turn
always forget so if we are on yala a
so on this
boy we have more green yeah so it means
the Preferred channel as a thick line
you can see it's on your left or you go
to the to to the left the port side so
but it's confusing yeah so what we
remember is from which side we need to
leave the boy to to remain the boy to
pass the boy on which side
so to
continue to follow the main Channel so
if this more green then you leave us on
your Starbucks side on yala a system and
you will continue with the preferred
Channel with the main Channel
okay enough for the uh this yellow B it
is opposite I will not put too much
attention on it we already spent so much
time
um Cardinal boy
yeah so I will also minimize a bit
okay as it is
simple we have
point of Interest or some shallow or
some danger and we have a yellow black
boys
which marks there where you will see
that two points up the black is up two
points down this triangular the black is
down so we go up and uh down so the
black is referredly and then they point
to each other the black is in the middle
so the we understand that that we need
to pass
on this side of the of the earth reality
on the North side on the south side
on the east or west
when we see this Cardinal boy so if you
pass on the north side of the Cardinal
boy
which is north carnal boy then we will
be safe if we go opposite then we are in
danger yeah
uh also they have flashes
white flashes
and
on we use it as a clocks yeah so we like
we have some 12 3 6 and 9 but the Norse
Cardinal boy it doesn't flash 12 it
flash quick or very quick
that's it continuously flashing
so the East Cardinal boy is
three
flashes the vest is nine and we need to
remember that the south is not only six
but six and long Flash the reason is why
if you have waves or off weather and
you're counting for example it's very
easy to let's say miscount nine flashes
and count like six and recognize this
a boy as a South one and in fact it is a
West one so to make a mistake so the the
sales one is six with long flesh
so we're already spoke about
isolated danger and don't have much to
add here you remember two flashes like I
know two eyes you need to pay your
attention your boss eyes on this has a
little danger and so on so too spherical
shapes on top
two black ones of course
then save Mark
say watermark
normally such Mark used as a Center Line
mid Channel or landfall boy or to
indicate the best point to pass under
the fixed bridge yeah so nothing to add
when we are entering some Narrows
normally close to
Fairway boy which normally marked as a
safe Watermark this red and white straps
with the red spherical shape on top
so the pilot is on and off so we are
taking the pilot or Pilot disembarks
next to this boy and also when
outbound vessels are coming they live on
the airport side incoming also on the
port side so they're passing clear
uh
what can be for example
either face flash which means the light
it turns on and turns off the same
period of time
occulting which means we see more the
light than it is off so it's much it's a
bit longer yeah this light on than off
opposite to flash when the flash is just
short period of time is on and then it's
off for some time yeah so like this long
flash every 10 seconds
or it can be Morse signal a which means
short and long
special Mark boys we already discussed
and they
have variety of flashes with the yellow
color light
and
marking new Danger
so here is description when the new
danger can be marked as with the lateral
boy with the Cardinal boy but this
yellow blue strap boy actually with the
same color of lashes blue and yellow is
emergency wreck marking boy so when
recently discovered rock or just a short
time from The Vessel which sank and we
don't know yet the least depths Above
This navigational obstruction so we we
also did not plot yet on the chart we
didn't receive a correction with The
Notches to Mariners information so
these obstructions this navigational
hazards are marked with the this yellow
blue strap boy with the upright yellow
cross on top
I hope you like this video and don't
