1 Properly speaking, the circular loop in a shroud or stay where it passes over a mast at the hounds. It is formed by splicing the ends of two ropes or wires into each other to form a loop to fit over the mast. But by extension it has come to mean any loop spliced or whipped at the end of a rope or wire, usually round a thimble. A Flemish eye is a method of making the eye in a shroud or stay by dividing the strands, knotting each part separately and then parcelling and serving. This method, though very neat, was frowned upon by all good seamen during the days of sail as it lacked strength where, for the safety of the ship, it was most needed.
2 The eye of the wind, or wind's eye, is a term used to describe the exact direction from which it blows, or when it is dead to windward.
3 The eyes of the ship is a term used to describe its extreme forward end, the term being derived from the old eastern and Mediterranean custom of painting an eye on each bow so that the vessel could see where it was going. By some it is considered that the hawseholes are equivalent to the eyes in a modern ship, but this is a somewhat doubtful attempt to fit the physical fact of modern ship construction to an older derivation.
5 The eye of the storm is the centre of a tropical storm where there is an area of calm.
6 An eye splice is a loop or eye made in the end of a rope or wire by turning the end back and splicing it through the standing part, usually around a thimble, with the length of the splice served to prevent fraying and to make a neater job.
