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. Ameen

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
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.
Fantastic explanation 🙏 thank you sir !
Excelent!! Thank You for your explanation.
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.

Good morning 🌞🌞 friend For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Amazing explanation. When will calculations part be available?
Thnxx for the info
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?
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
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
thank you sir , what about next draft survey video? its been a year
Very useful information Sir

Sir please advise me if I can contact you
Just wanted to confirm that we must add heel correction?
@SteeringMariners

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).
How to get the distance a, b & c
Thnks a lot Sir

Why must owner surveyor. Charter surveyor. Ch. Mate/master. Consignee. Loading/discharging terminal authority attend draft survey????
👍
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?

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
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
