- Buoyage video explanation looked at with a how to "Captain" or "Navigator" perspective - to give a practical understanding. In the middle of a stormy night - when a buoy flashes, you need to know instinctively, what to do.
Buoy Chapters
0:00 Introduction to marine buoys and markers
0:49 IALA regions (B) USA and (A) Rest of world)
2:01 Safe water - safe navigation all around the buoy
2:37 Isolated danger - small areas of danger in immediate vicinity
3:33 Lateral - marking the sides or port and starboard limits of navigation channels
4:40 Special - other areas where various activities are / are not allowed - military / swimming / jetski / private palaces
5:18 Cardinal buoys - indicating safe direction of navigation ie which direction is safe to be in (opposite indicating the danger)
6:28 North Cardinal (stay North of the buoy)
6:52 East Cardinal (stay East of the buoy)
7:19 South Cardinal (stay South of the buoy)
7:59 West Cardinal (stay West of the buoy)
8:22 Emergency Wreck Marker - wrecks - submerged or partially submerged ships wrecks and danger to other vessels
9:08 More info on the website www.coastalsafety.com
If you remember the 10 types of buoy - then it is easy to remember.
Especially when you group the buoys together
1 &2) LATERAL CHANNEL - marking channels (PORT & STARBOARD)
3, 4, 5 & 6) CARDINAL - indicating safe direction of navigation (North East South West)
7) ISOLATED DANGER (NO - do not come here) - danger in the immediate vicinity of the buoy
8) SAFE WATER (YES it's OK to come close)- safe navigation all around the buoy
9) EMERGENCY WRECK (do not approach) - submerged and partially submerged ships wrecks and danger
10) SPECIAL (only approach if you know what is there)- other areas where various activities are / are not allowed
These are simple ways that we teach the basic foundations ... from which we build greater knowledge.

(Red or Green - Port or Starboard) - (Americas or rest of the world)
Region A covers Europe and most of the of the world (red to port side).
Region B covers the America, Japan, the Philippines and South Korea (Green to port side).
Flash - less light & more darkness
Long flash - longer flash but still less light & more darkness
Isophase - equal time of light and darkness
Occulting - more light & less darkness
LATERAL CHANNEL marks are used generally to mark the sides of well-defined, navigable channels.
They are positioned in accordance with the "Conventional Direction of Buoyage" as discussed above. Port and Starboard lateral marks tend to be can shaped on the port side and conical shaped on the starboard side - this makes them easier to identify in low light or reduced visibility conditions.
CARDINAL buoys and marks warn of danger and remain constant throughout the system of two IALA regions. There may be only one buoy or more depending on the danger and the shape of the coast. For example, close to the shore they may be only one buoy as it may not be possible to go between the wreck and the shore. The buoys have two black cones in different configurations which are know as the "top mark" cones - these point to the black areas on the body of the buoy - the rest of the buoy is yellow.
The body of a cardinal buoy is always marked with a combination of black and yellow bands. It is always surmounted with a topmark consisting of 2 black triangles arranged in 1 of 4 combinations.
Cardinal Marks are used in conjunction with the compass to indicate the direction from the mark in which the deepest navigable water lies, to draw attention to a bend, junction or fork in a channel, or to mark the end of a shoal.
The buoys indicate where the safe water is:
North of a North mark
South of a South mark
East of an East mark
West of a West mark.
ISOLATED DANGER Marks are used to mark small, isolated dangers with navigable water around the buoy. They are used to mark an isolated hazard in waters which otherwise are navigable. The pattern of bands is BLACK over RED over BLACK. The topmark is 2 BLACK balls. If lit, the light will show 2 WHITE flashes (Fl 2).
They can mark:
- a small area of rocks
- a pinnacle rock
- small sand bank
- old collapsed buildings in the sea
- pipes that are a danger to surface navigation
SAFE WATER marks may be used at the seaward end of the start of a channel to a port, mid-channel, as a centreline markers or at the point where land is reached.
These buoys (as the name suggests) indicate the presence of safe, navigable water all around the buoy.
EMERGENCY WRECK Buoys provide a clear and unambiguous means of marking new wrecks.

• Understanding Marine B...
Did the thing of searching UA-cam for a topic and opening a load of tabs hoping to find one video that explains it well. This was that video. Nice work.
Awesome, thank you!
VERY USEFUL AND INFORMATIVE VIDEO FOR A MARINER WHO FINDS VERY HARD TO DIFFICULT TO UNDERSTAND FROM BOOKS.
The tips for remembering the buoys are exceedingly usefully.
Glad you like them!
Love the structure, the explanations and the tips! So helpful! Thank you for taking the time to put this together! Really appreciate it :)
Thanks you so much for your kind review 😀
Thanks this is the best description I have seen.
Glad it was helpful! I am happy to receive suggestions for new videos :-)
Perfect. I am going on a yacht trip as crew next week from Ardfern to Kirkwall and wanted a refresher on buoyage.
Awesome - enjoy your trip :-)
Great video...Thanks for the explanation 🎉
Thanks for making it so easy to remember.
You are welcome - enjoy learning 👍
Amazing work thank you
Thanks for making this video 💯
I have an sponsorship exam coming up around the week and this info was much needed... accept my true gratitude 🙏🏻

Not yet but I'm going to thank you. Delighted to have found this channel.
@@dawnh6377 You are most welcome :-)
Very well said
That's great - thank you :-)
Thank you🙌
Is great to receive your appreciation. Did you try our buoyage "video self test"
@@CoastalSafety fantastic video I'll be sure to check out the bouyage self test 🙏
Were will I find this?
this was a massive help in understanding everything 🙌
Absolutely awesome 👌
Thanks for the response
Thank youu very much..So helpfull..i watched so many time..talking fast but awesome...
Glad it was helpful! I am happy to receive suggestions for new videos :-) Also, we are happy for people to help with translating the subtitles in to other languages. We can send you a date stamped transcript to translate :-)
Thank you
Thank you for watching - did you try one of our "self test" buoy videos? ua-cam.com/video/Wjwm5mF8CNk/v-deo.html
Good explain - very nice
Thanks - your comments are much appreciated - please feel free to share with your friends
thank you for the thank you :-)
Brill...the whole visual memory trick is what i use to stick stuff in the old grey cells. I remember that latitude is a long fence ie horizontal and longitude is a flag pole...so i visualise looking up at a flag ie vertical, daft I know but i will always remember the difference.
Thanks for the upload very helpful 👍
:-)
:-)
Whatever helps you remember is good :-) We use LONGitude is aLONG the bottom of the chart. LAtitude is like climbing a LAdder = they all work :-)
Thanks.
Try one of our Buoy self test videos ua-cam.com/video/Wjwm5mF8CNk/v-deo.html
Thanks sir
You are very welcome sir - enjoy safe sailing
thank you so much! 😁 very informative :)
You're very welcome thank you for your appreciation
Stay tuned more videos are in the pipeline. We are just fine tuning them to make them more easy to understand
@@CoastalSafety okay, I'm an aspiring deck officer :) soon to be 🙏☝️
Our videos will certainly help you. I wish videos like ours were available many years ago when I started my cadetship to be a deck officer
@@CoastalSafety yeah there's no youtube or other media that will help you back in the day other than reading books.
thanks bruv
Thank you for your appreciation
it could look like an egg?? whahah nice vid thanks!
Glad it was helpful! I am happy to receive suggestions for new videos :-)
1:04 one of the region using IALA system A is wrong.ROC(Taiwan) uses IALA B system
Time to be independent You are most welcome :-)
So where are you supposed to go with each bouye?
North, South, West, and East buoys, these are the cardinal buoys and they tell you which direction you must go to the safe water. Port and Starboard buoys tell you tell you where the safe water or channel is, normally entering a harbour or river.
Safe water or sometimes called fairway buoy tells you where you can go and the isolated danger buoy tells you where you should not go.
Special buoys indicate a special area for special activities.
Emergency Wreck buoy indicates she a vessel has recently sunk, so probably best not to go there also.

Stat away from two black balls, Or you will BALLS IT UP.
Same for Isolated danger buoy!
