Understanding Gross Tonnage and Net Tonnage: Key Differences Explained
Переглядів 84021 годину тому
In this video, we break down the difference between Gross Tonnage (GT) and Net Tonnage (NT) in simple terms. Gross Tonnage, represents the total volume of all enclosed spaces in a ship. It gives us a picture of the ship’s overall size and capacity. It’s not about weight but the size of the ship based on the spaces enclosed within its hull and superstructure. Net Tonnage refers to the volume of ...

Thank you.
Relative vectors are the same of relative motion?
Thank you for the question. Relative vectors and relative motion are not exactly the same, though they are closely related. Relative vectors: These are graphical representations on the radar screen that show the direction and speed of a target relative to your own ship. They are typically used to visualize how a target appears to move from the perspective of your vessel. Relative motion: The own ship is shown as stationary on the radar PPI (Plan Position Indicator), and only the surrounding echoes (other vessels or objects) appear to move. This display represents the relative motion of targets as observed from the perspective of your ship. Here is the link to my other videos that explains in details the relative and true motion display & the relative and true vector: ua-cam.com/video/9jKumYQvLS0/v-deo.html ua-cam.com/video/_gCRehulxgc/v-deo.html
You deserved a lot of subscribers, thank you for sharing this information.
Thank you so much for your kind words and support! I'm glad you found the information helpful. Your encouragement means a lot and motivates me to keep sharing more valuable content. 😊🙏
@@nauticalacademy001 yes sir! looking forward on your next informative video. All the best!
Can you make a video clip on correcting the magnetic compass on a ship?
Thank you for your suggestion! That’s a great topic, but unfortunately, I can't create this video right now as I'm not onboard. I’ll definitely keep it in mind for the future when I have the opportunity. Appreciate your understanding and support! 😊

Great thanks Mr. Capt for explanation
Welcome & thank you.
It really helps. Thank you so much for such helpful video. May I know from which website you take this kind of animated video?
Thank you so much for your kind words! I'm glad you found the video helpful. 😊 The animation was created entirely in PowerPoint using the Morph Transition feature to move the objects smoothly. The radar and its display animation were also custom-made in PowerPoint. Thanks again for your support! 🚢✨
I like on how he demonstrate... Very clear and understandable. This video will help my fellow seafarer to expand there learning. Its been highly appreciated🙏
Thank you.
can you give an example on how the DWA is calculated to 242 and 248?
I will try.
Thank you so much sir.
You're welcome.
Is it accurate to use bilinear interpolation on mean drafts 9.25 9.250375 9.26 trim 1m or 1.5m 1.937m 2m.??? Cause i see other calculation they only use linear interpolation in mean drafts at 0 trim
Thank you for your comment! Bilinear interpolation is indeed more accurate when the data supports it, especially for large trims. For small trims or when tables provide data only for zero trim, linear interpolation is typically sufficient. If mean drafts (e.g., 9.25, 9.250375, 9.26) and corresponding trim data (e.g., 1m, 1.5m, 2m, etc.) are available, using bilinear interpolation ensures greater accuracy by accounting for the interaction between these variables. Thanks again for your input!
clear and understandable😄
Thank you.
You are the best❤ how to easy to understand, many thanks,

Excellent content, thanks - on my android phone, I had trouble accessing the download location of the ENC file due to an android restriction, but there is an option in the paid version to 'Migrate Charts', and this allows you to specify the location of the extracted file folder, and worked.
Thanks for sharing this tip! It could be helpful for others facing the same issue.

Very nice could upload how to get the lcg if the ship is china made were starting point is aftperpendicular thanks
Thank you! I’ll will try to make a video on how to determine the LCG especially for ships made in China.
@@nauticalacademy001 your vlog help alot to all deck officers s tks
Thanks a lot. It's helpful. Could you please upload more videos showing & explaining different parts of the ship.
Thank you! I’m glad you found it helpful. I appreciate the suggestion, and I’ll definitely consider making more videos covering different parts of the ship. Stay tuned for future uploads!
@@nauticalacademy001 Thank you very much.
What if I kept sog and swtiched vector to relative ? Then will it show the same screen as that of stw on radar?
Thank you for the comment. If the radar is set to relative vector mode, the vectors will appear the same regardless of whether you are in SOG (ground-stabilized) or STW (sea-stabilized) mode.
@nauticalacademy001 thankyou sir
Ron, agradecido por entregar tus conocimientos a los futuros hombres de mar, saludos..
Thank you.
Good content, I'm following
Thank you.
good instructive video but unfortunately the App does not for Android 14. do i have any link for something compatible with Android 14 🙏
Thank you for watching! I'm glad you found the video instructive. I haven’t personally tested this app on Android 14, as it typically works on lower versions. Unfortunately, I don’t have a link to an alternative compatible with Android 14 at the moment.
This explanation why no multiple SF like part 1 for each hold
In this video, it has only one type/grade of cargo (coal), so only one SF, the same as part 1. In part 1, it has only one SF because the cargo has the same type/grade. Kindly review part 1, thank you.
@nauticalacademy001 Thank you Sir,
How about there are 3 grades of cargo different SF can you make a vlog tks
Agradecido, muy didáctico, saludos..
Thank you.
Nice video..❤
Thank you.
Nice vlog how about summer loading port about 7days she pass to winter in certain latitude and longitude position that when she pass she will be in winter tks
Thanks for watching! Great question-to maximize the loading capacity from the loading port (summer zone) to winter zone, coordinate with Chief Engineer to confirm ROBs of FO, DO & LO upon arrival in the winter zone . Share details of the voyage plan, especially the distance from the loading port to the winter zone, then calculate the loadable cargo considering other consumables onboard using the loading-back method. If the vessel carry more cargo while sailing within the winter zone following the permissible winter draft, be sure that upon arrival at the discharge port draft requirements are complied, recalculate consumables from the winter zone up to arrival to ensure compliance with draft restrictions in the discharging port. This approach helps you maximize the loading capacity of the ship, maintain safe and compliant drafts requirements throughout the voyage. Thanks
The worst part of the exam and the most useless in real life hands down.
Hello sir. I want to know your Encs compiled edition? I have a 2017 edition same same you.
the link is in the comment section.
@nauticalacademy001 i know sir. I mean which year your charts up to date
Excelente muy agradecido por la información me servirá para la navegación y el estudio
Thank you very much for your comment! I’m glad to hear the information will be helpful for your navigation and studies.
Very usefull video for chief officers
Thank you.
could you please sir give us link for having a simulator radar , and think you for all your efforts
Thank you for your kind words! I currently don’t have a radar simulator installer. The radar display you see in the video is actually a replica I created in PowerPoint to animate the radar motion display. If I ever get access to a radar simulator, I’d be more than happy to share it with all of you. Thanks again for watching!
