In this video, I explain reserve buoyancy and why ships need it. I also highlight an important mistake students make when answering questions related to this topic in oral examinations. In my next video, i will explain the procedure of calculating it using a numerical as an example.
Students are advised to watch the previous videos (links below) before watching this video.

The new marking/lebelling, teaching is great...it gives the effect how you teach someone in the class on a black board... Alwys wanted that in your explanations...Thank you Captain for innovating new techniques to teach..
Helpful video 👍👍👍

I am going to have my report next week. Thanks to this informative video.
sir your channel is one of the best for mariners ... keep up the good work sir , it really helped me during my 2nd mate preparation. may you reach 100 million subscriber . god bless you sir .
Thank you so much, really appreciate the kind feedback 😊
Welcome sir 🙏

Your way of teaching helps me to learn quickly
Excellent video and well explained, I subscribed due to your excellent explanation.
Thank you for this 👍🏻
Good video👍👍👍
Perfect👍👍👍👍
Hi sir...Thanks for the video. Could you please confirm the upper wing ballast tanks can be reserve buoyancy? Or even the underdeck passage on the container ships can be taken as Reserve buoyancy?
Hello sir. I would like to ask, if a ship is loaded in summer zone and the discharging zone is in winter zone, until what load line should you load?
Are the cargo holds in bulk carrier above waterline serve as reserve buoyancy sir?
For ships carrying timber cargo will the timber cargo also helps to increase reserve buoyancy?
I would like to know how to calculate the reserve buoyancy
Thanks sir
Sir, does RB displaced any water?
Does ballast tanks serve to reserve buoyancy in a loaded condition?
Not really, they are mostly below the waterline.

Sir what are the areas to be considered for reserve buoyancy.
Any spaces above the waterline, for example, watertight doors, shell plating, armored bulkheads, segregated compartments, void spaces, etc.
@@SteeringMariners thank you very much sir
Sir is reserve buoyancy same as intact buoyancy?
