Hi, this is Vikas Upadhyay ( Sailor Vikas ) and I am in Merchant Navy . ⚓

I sail big ships in the capacity of First Officer in Anglo Eastern . 🚢

I have done my Pre-sea training from ANGLO EASTERN MARITIME ACADEMY (AEMA),

My aim is to make Maritime knowledge more simple to understand as I feel things are made complicated for no reason by using unnecessary hard words in all theory topics whi

📡 RADAR: Ground Stabilization vs Sea Stabilization
Most cadets get confused — but the difference is simple:
• Ground Stabilized → Uses COG/SOG → Shows TRUE motion → Best for collision avoidance.
• Sea Stabilized → Uses Heading + STW → Shows RELATIVE motion → Best in strong currents & close maneuvers.

In this reel I break down both in the simplest way so every OOW can make the right choice on watch. ⚓
Follow for daily marine lessons! 🌊

Anchor Joining Shackles:

Two lengths of Anchor cables (shackles) are joined together using an ‘Anchor

Joining Shackle’. There are two types of joining shackles, ‘Lugged Joining Shackle’ and

‘Lugless Joining Shackle’. Modern vessels are provided with Lugless Joining Shackle.

 

1. Lugless Joining Shackle:

A ‘Lugless Joining Shackle’ consists of two main parts with one ‘Stud’ in between.

The two main parts are attached to the ends of cable, then fitted together and then the

stud is inserted in between. The whole assemble is then secured together by hammering

in a ‘Tapered Pin’ through a hole drilled diagonally through both main parts as well as the

stud. A ‘Lead Pellet’ is then hammered in at the broad end of the pin which keeps the pin

in place.

2. Lugged Joining Shackle:

A ‘Lugged Joining Shackle’ (see figure above) even though less common now-a-days may

still be found on some smaller vessels. It consists of a straight shackle whose bolt will be

secured using a tapered pin and a lead pellet. The pin fits into a tapered hole drilled

through the bolt and one lug of the shackle. Except for the Anchor shackle, all lugged

shackles should be fitted into the cable with their lugs facing aft so that they will not foul

when the cable runs out. Since the anchor shackle is already inside the hawse pipe, there

is no danger of it fouling anywhere and so it is fitted with its lugs facing outboard.
