Really I appreciate to make this video for those who need to understand for exam purpose and don't need actually while working onboard and cannot learn it onboard
Thank you for your feedback! I'm glad you found the video helpful, especially for exam preparation. While some concepts may not be used daily onboard, understanding them is crucial for exams and overall maritime knowledge. Thank you.
@@nauticalacademy001 yes sir of course ,I am engine side I don't know anything about naval architecture and especially about stability related ,after watching your videos I had some confident that I can understand naval architect concepts for my exams ,thatnks a lot great work
Dear Sir your videos are very clear for all seafarers who want improve their knowledge in the nautical science.But i have a question.....are you planning in the future video concerning the resolution of celestial navigation problems also?Thanks for Your answer..Kind regards!Lorenzo, Italy
I take it the ship will heel around the center of gravity (no weights have been moved), and not the initial center of boyancy. A sailboat generally have a very low center of grafity, mine is a foot under the waterline. Will it also rotate (heel due to wind forced) around the center of gravity. The hull form makes the center a boyancy move a lot to leeward when heeling. The pressure from the wind acting on the sails, will set it a little deeper in the water?
@nauticalacademy001 First time ever I'm commenting on youtube and this is only because your content is so well organized that it saved my time and I just cleared my doubts....Thanks a lot, love from south Atlantic ocean💙😄
can you please show us how to draw gz graphic according to our calculated gm value?because port states usually wants to see the graphics drawn by ship officers by hand not with the program so please show us drawing the gz graphic with our calculated values
In the context of ship stability and dynamics, the moments (represented by £ X•Y•Z in your comment) can indeed cause a ship to rotate or revolve around certain angles. Here’s a brief explanation: Moment: A moment is a measure of the force causing an object to rotate. In physics, it’s calculated as the product of the force and the distance from the point of rotation (lever arm). Axes of Rotation (X, Y, Z): These refer to the three principal axes in a 3D coordinate system. X-axis: Typically runs from the bow (front) to the stern (back) of the ship. Y-axis: Typically runs from port (left side) to starboard (right side) of the ship. Z-axis: Typically runs vertically, from the bottom (keel) to the top (deck) of the ship. A ship can rotate around these axes due to the moments acting on them, resulting in different types of movement: Roll: Rotation around the X-axis (side-to-side tilting). Pitch: Rotation around the Y-axis (up-and-down tilting of the bow and stern). Yaw: Rotation around the Z-axis (left-to-right turning of the bow). When a moment acts on a ship, it creates a rotational force that can cause the ship to rotate around one or more of these axes, changing its orientation in the water. For instance, a moment around the Y-axis (X•Y•Z referring to Y) would cause the ship to pitch, while a moment around the X-axis would cause the ship to roll.
Correction for the formula that I've shown:
Righting Lever (GZ) = GM x Sine0 (Angle of Heel)
Righting Moment (RM) = GZ x Displacement
Good job, which software or program is used for simulation
Finaly I found a FLAWLESS explanation of Ships Stability. No questions left. A Huge thanks. Liked and Subscribed!!!
Thank you.
This was a perfect explanation of ships stability...especially to understand the metacenter!
Thank you, I'm glad you found the explanation helpful!
very concised and informative, as well as good graphics too. very well explained.
Thank you.

I just started studying at a naval focused polytechnic college. Your videos will be very useful for my further studies. Thank you very much.
Happy to hear that! May I ask which school you are attending for your naval course.
I am from, Bangladesh Institute Of marine technology.
It is a deploma course @@nauticalacademy001
@nauticalacademy001 I went to ship polytechnic of Surabaya, Indonesia. The only college in Indonesia that is focused on ship building.
I'm in final year of studying naval architecture in VietNam, can we connect?
@uchihaobito1581 Im only at the final first semester. But if you want to connect im free to do so
THANKS FOR THE INFORMATIVE VIDEO.
Welcome.
clear and understandable😄
Thank you.
very useful explaination.
Glad it was helpful! Thank you.
thanks for sharing,great help❤
Welcome.
It is easily to understand!
I'm glad that my video helps you. thanks for the comment.
@@nauticalacademy001 what school did you lecture before?
Just like your spelling is easily to laugh at
@ thanks for your fixed!
a nice one!
Thank you.

Thank you. I'm glad you found my video valuable. Yes, I'm planning to upload a video on celestial navigation calculations soon.

already subscribe thank you
Thank you too.
can you please show us how to draw gz graphic according to our calculated gm value?because port states usually wants to see the graphics drawn by ship officers by hand not with the program so please show us drawing the gz graphic with our calculated values
I will make a seperate video on how to construct a gz curve manually.
@@nauticalacademy001 it will be so important and useful information for us, thank you
where is the video of the sample calculation of GZ and RM..
Here is the link for that video. ua-cam.com/video/dGu3m7-xNgg/v-deo.html

sir does in revolve on their certain angle due to moment £ X•Y•Z?

Bro are you from buet?
Thanks for asking! No bro, I'm not from BUET, but I appreciate your curiosity!
👍🏼
Thank you.
Anybody watching this for JEE ..?
Thank you for watching.
@@nauticalacademy001 your welcome… Btw the video was cool
