This video teaches the important aspects of calculating Fresh Water Allowance (FWA) and Dock Water Allowance (DWA) as vessel moves in water of differing densities. Questions from Capt Subramaniam's Ship Stability are used as examples for student understanding.

Thank you so much !
Thank you sir , your videos are very helpful for written and oral exam. With your guidance I passed my exam for 2 mate uk in 1 attempt thank you very much sir .
Congrats and very well done. I am glad the videos helped 😊
Thanks, sir! You've helped me a lot with a challenge our teacher brang to us. Greetings from Brazil!
I really appreciate
Thank you so much,sir
Very clear! 👍
Very well explained 🙏 thank you sir !
Thank you very much sir for providing very useful info..
Thankyou sir
Very helpful
Jai hind
For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Thank you sir:-)
thank you so much sir, i will be reporting this topic god bless
Thank you very much sir.
Very well explained 💯 thank u sir
Greetings 🙏 Sir ! I would like to take the pleasure in wishing you and all your family a very Happy , prosperous n blessed New year 2022 🙏 with deep gratitude I want to thank you for all the awesome n wonderful learning videos you have expressed on "RUclips" that has benefitted me and many others I'm sure ? Thank you 🙏 may God bless you always for the kindness n concern you share on knowledge of nautical science to the ones in need ? Your great help is deeply appreciated 🙏 all my blessings and prayers to God are for you in this respect 🙏🙏🙏 🙏🙏🙏
Thank you so much my friend, I wish you and your family the same. I appreciate your good wishes from the bottom of my heart. Would love to know more about u:)
Good day Sir.I have question regarding this topic.But how can we calculate if vessel sails from fresh water to dock water or vica versa.Because we talked only respective to salt water when we calculate FWA DWA
What will be the change in tpc regarding density....if a ship is going from sea water to fresh water...what will be the effect on tpc ?
Thank you sir🌸
Sir , i have request
Could you explain how to draw ship lines manual by using offset table and how to draw the knuckles🙏🙏
Thank you
I have a question
If my vessel is in density 1.015 and ship will sail to SW density and ship will be take full cargo.
Vessel in summer draft 9.54 (1,025)
But vessel in density (1,015) after making DWA there will increase the draft 8.5 cm will be 9.625 m
Is it allowed to loading to this draft without any question from harbor master why ship is over load summer draft.
Sir , 1 degree how many centimeters
t/m3 or kg/m3 ?
