No words to express gratitude for your all efforts for putting it so simple.
We as Indian seafarers are in large numbers in the industry but very few think and feel its your responsibility to contribute to the fellow seafarers.
I wish many can come forward just like you to help the world of seafarers.
May you all have safe and healthy sailing.

Thank you for your kind comments. I really appreciate it:)
I bow and thank you from the bottom of my heart everytime I see one of you magnificent videos.
These educational videos of yours are a blessing and a favor from you to all mariners of the world.
Thank you, Tank you.
Pl
You are awesome thanks for creating this channel 😊 please create a playlist for oil tanker vessel
could'nt been explained better than this... thank you
Sir ,for me your explanation is very well clear and waiting for next video. Thanks...brgds
Fantastic explanation 🙏 thank you sir !
Excelent!! Thank You for your explanation.
according to the drowing where the aft draft mark line is more ahead from AP it should be read with mark "+" and forward perpendicular (FP) is ahead, so it should be read on the forward mark"-" same as a middle draft during the trim correction.
it's a great video, thanks
Great information sir ⚓
It my pleasure to say tx case u teach me a lot about ship.
Thank you for intersting explanation but in first trim correction calculations the formula looks like mistake, as I know that 1st trim corr'n = TrueTrim (cm) x LCF x TPC and devided by LBP.
If possible, pls give me a good reference for learning Draft survey
Thnxx for the info
Dear Sir, waiting for your next draft survey video. Thank you very much.
Good morning 🌞🌞 friend
For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Amazing explanation.
When will calculations part be available?
Very useful information Sir
Sir please advise me if I can contact you
We are in need to know how to use and get the info from stability booklet
For Draft correction divisor Fwd = Trim x Dist. to FPerpendicular divided by Distance between Draft Marks to make simple the equation denumenator = ( Distance between draft marks) am I correct please correct
Thnks a lot Sir

When keel thickness is considered in the draft survey, for example 0.018m, which displacement needs to be considered as correct? moulded or extreme displacement?
Thank you very much good explanation but in 1st trim correction the formula for calculation i am not shure that is correct as i have «1st trim correction=Corrected trim X 100 X LCF X TPC / LBP
Just wanted to confirm that we must add heel correction?
In theory, the quarter mean draft does take care of the heel correction. But the surveyors will never ask you to ignore the heel correction (subject of discussion between theory and practice).
👍
thank you sir , what about next draft survey video? its been a year
Why must owner surveyor. Charter surveyor. Ch. Mate/master. Consignee. Loading/discharging terminal authority attend draft survey????
How to get the distance a, b & c
Sir one question
If vessel is hogged, fwd and aft draft already submerged, still 10 cm for plimsoll, can we load further or not, if yes , why?
Yes you can load close mid ship
Why not ???
@ Steering Mariners formula for 1st trim correction is wrong...can you please check...

Sir I want to learn the drop survey please provide one on video on realtime
FWD P + FWD S ÷2 IS FWD MEAN
MID P + MID S ÷ 2 IS MID MEAN
AFT P + AFT S ÷ 2 IS AFT MEAN
IF FWD DRAFT CORRECTION IS - THEN -0.003
IF MID DRAFT CORRECTION IS - THEN -0.003
IF AFT DRAFT CORRECTION IS + THEN +0.003
0.003 IS ONLY I WRITING
THIS IS RIGHT SIR
Draft survey problems pls
Quarter mean simply means the mean draft has been averaged for 4 times, its not the quarter value of mean draft.
Where's the k.s captain???!!!
Please Tamil explain sir
sir too many ads on your video
Your first trim correction formula is incorrect dear friend
