(Categories of Zone Of Confidence) is a rather simple aspect of understanding ECDIS and electronic nautical charts (ENCs).
On ECDIS, the CatZocs are symbolized by a number of stars. A map with six stars means the information is very accurate and with two stars very inaccurate

What is in ship stability?

This rise /change in draft is called as Fresh water allowance FWA.

Summer draft + FWA = Freshwater draft.

If the vessel is loading in fresh water , She can load Upto fresh water draft. When the Vessel travels from FW to SW, She will rise and her draft at salt water will be summer draft.

FWA = W/(4 x TPC).
Where 'W' = Loaded SW displacement in tonnes.

? ... 👌👇

Ship’s length (Bridge GPS antenna to fwd) + (How many shackles x 27.5m)

FOR Example :
= 8 shackle on deck and (bridge GPS antenna to fwd) is indicated by L = 160m
= 8 shackle +L
= 8×27.5m +160
= 380 m
= (380 / 1852 ) nm
= 0.2052 nm
= (0.2052 ×10) cable @ one NM is equal to 10 cable
= 2.052 cable

Note :
Centre of swinging circle is the point where anchor fluke touches SEABED.

Alternatively, The following is the formula used to calculate Swing Radius of a boat at anchor.:

Swing Radius = LOA + [ ( RODE ) 2 – ( DEPTH + FREEBOARD)2 ] 1/2

LOA: Overall length of the boat, including any additions or extensions from the stern

RODE: The length (line to the anchor) of the rode from the bow pulpit to the anchor.

DEPTH: The water depth over the anchor.
FREEBOARD: The distance from the deck at the bow pulpit to the water.

Note all measurements of length and distance must be in the same units. 👌

Dalam kebanyakan situasi yang terjadi ketika menghitung error kompas atau menghitung garis situs dengan mengamati kejahatan langit atau matahari, kita melihat kejutannya ketika meminta menggunakan mesin soket atau sebaliknya jawabannya adalah sebagai berikut: Kita belum pernah menggunakannya sebelumnya atau sudah Sebuah program untuk menghitung waktu, tinggi dan arah matahari setiap menit, Ada juga program untuk menghitung error kompas dengan cara memasuki situs, terlepas dari semua hal diatas

Teman, melalui studi Anda di akademi atau lembaga angkatan laut mana pun, ada subjek yang disebut navigasi astronomi, yang melaluinya semua definisi astronomi diakui dan bagaimana cara menghitung ketinggian dan arah kejahatan langit dan planet, meskipun seperti yang Anda sukai dan katakan bahwa tidak ada Perlu definisi dan perhitungan yang rumit seperti itu, dengan adanya program aritmatika yang membantu kita Dengan mengorbankan segalanya, itu berarti Anda tidak ingin mengembangkan pengetahuan Anda yang seharusnya penting untuk berada di ruang komando sebagai perwira angkatan laut.

Terlepas dari enam mesin dan pentingnya, jika tidak memiliki kepentingan untuk steamer itu akan ada hari ini, dan sebaliknya itu tergantung pada program komputer pada perahu, dan manual almanak bahari tidak memiliki kepentingan untuk steamer,

Saat ini, terdapat kesalahan dalam perhitungan kesalahan kompas, mengetahui bahwa hal itu sangat penting, seperti yang disebutkan dalam buku Solace bahwa setiap petugas patroli harus menghitung kesalahan kompas dan mencatatnya,

Di akademi kita diajarkan dasar-dasar tetapi di laut kita harus menerapkan dasar-dasar ini di lapangan bukan untuk menghindari mengungkapkan otoritas pelabuhan tetapi bagi Anda untuk menjaga pengetahuan dan pengalaman Anda up to date di laut yang merupakan salah satu dasar dari pekerjaan Anda di dalamnya.

Juga untuk akun marine atau program soal keseimbangan yg beredar..... Apakah ada program keseimbangan di kapal? ,
Jika program-program ini adalah dasar dari pekerjaan Anda, Anda tidak akan menemukan buku keseimbangan, kasus khusus, dan tabel pengukuran lelucon.

Semua petugas harus tahu cara menggunakan mesin senjata dan juga perhitungan yang terkait dengannya karena itu adalah salah satu dasar dari pekerjaan dan studi Anda

Kami berharap semua petugas semoga beruntung dan sukses

The stay of the ⚓️ chain is to be reported by the duty officer of the chain is the tendency of its movement .

: when the anchor cable is leading long with the weight on it.

: when the anchor cable is leading medium.

: when the anchor is hove in close to the ship's side and not extended long , also the cable is not up and down .

: when the anchor chain is sighted vertically leading to the ship's side .

: The anchor is said to be a weight as soon as anchor fluke is out of the seabed and is clear of the sea bed .

: The anchor is said to be dragging when it do not hold to the sea bed .

👉To all deck officers, please check the deviation card which posted in the wheelhouse must be : 👇👇👇👇

Deviation on any heading should be 5° or less.

: 2009 (E) requires a properly adjusted compass in vessels of 82.5 metres or above to have residual Deviations of no more than 3º and after the vessel's second adjustment after construction not to exceed 5º in any latitude in which the ship may operate.

🤔 Rescue Boat turned to bathtub 🛀 . What's the reason behind this ❓

Drain plugs or valves can easily get clogged by dirt and other foreign materials.

Check and clean it regularly as per your LSA checklist and PMS to prevent this from happening.

✅Check lashing condition, not too tight or not too loose

✅Visually inspect the hull for deformations, defects or cracks especially near joining edge of fittings.

✅Check the drain valve, cap/plug for any dirt deposits

✅Check opening/closing condition of compartments for watertight integrity.

✅Visually inspect overall paint condition

✅On/off test search light, canopy light and ships illumination light.

✅Together with enigineers, test the engine ahead and astern for not less than 3 minutes.

✅Check the pressure gauge of accumulator of Rescue Boat davit if charged.

"How do you determine if you are using the latest Monthly Checklist of LSA and FFE?"

Or generally speaking

"How do you know if you are using the updated Forms?"

Before I give the answer, ask yourself this:

Why is this important?

You see,

The Safety Management System (SMS) of a company is continuously improved &
updated based on feedback and lesson learned.

Its like constantly looking for ways to make things safer and better.

As such, Company Forms that are being used onboard are updated as well.

Here's a sample scenario:

A new regulation was reflected on the SMS, let's say, an additional fire
extinguisher should be placed on the laundry room.

If you are unaware that the SMS is updated, you will not be able to comply to this regulation.

This can result to a PSC deficiency.
-----
So what is the answer to the question🤔?

Simply check or download a form directly from you SMS and check the revision number & revision date.

The process of accessing the forms vary from company to company, so ask the
help of an officer about this.
