Sailing carabiners are fastening devices used to quickly connect and separate various rigging elements (ship's equipment), such as sails, ropes, sheets, and other accessories. They are metal hooks that open via a lever or spring mechanism, allowing objects to be easily attached or detached without the need for complex knots.

Main features of carabiners in sailing:

Material : They are generally made of stainless steel , which is resistant to corrosion from salt water and weather conditions, but aluminum versions are also available to reduce weight.

Shape and design : They have a "D" or "O" shape and feature a locking mechanism that prevents accidental release of the load. Some carabiners have a locking system for added security, while others are more basic.

Function : They are used to attach sails, halyards, sheets, or other equipment to the boat, facilitating setup and dismantling. They are very useful tools, especially in racing sails, where speed is essential and quick solutions are needed.

Size : Snap hooks come in different sizes, depending on their specific use. For example, smaller snap hooks can be used to attach sheets, while larger ones are used to attach sails or halyards.

Types of carabiners : In addition to the classic version, there are screw carabiners for greater safety, carabiners with automatic leverage , or carabiners with a safety lock to prevent accidental opening.

In short, snap hooks are essential components in a sailing boat's rigging, allowing for quick, safe, and convenient operations on board.
