what is the purpose of bowline in ship

The purpose of a bowline on a ship is to make a secure fixed loop at the end of a rope that won’t slip under load and is easy to untie afterward.

What it’s used for

• Securing a line to a ring, post, cleat, or buoy.

• Helping hold a square sail steady in historical sailing, especially to keep it from being taken aback by the wind.

• Mooring, towing, and general shipboard rigging where a strong but removable loop is useful.

Why sailors like it

• It stays the same size even when pulled hard.

• It does not jam easily, so it can usually be undone after use.

• It is reliable for temporary or semi-permanent fastening on deck.

In short, the bowline is a classic shipboard knot for making a dependable loop that holds firmly without becoming impossible to untie.
