What size is the twist shackle attached to the black thimble on the hydrostatic release for the lift raft?

Explanation:
The size is chosen to match the connecting hardware on the hydrostatic release setup, ensuring a clean fit and enough strength for the lift raft’s release path. In standard liferaft assemblies, the twist shackle that attaches to the black thimble on the hydrostatic release is 5/16 inch. This size fits the thimble’s eye, allows the pin to operate freely during release, and provides the necessary load rating for the deployment sequence. A larger size would be unnecessary and could interfere with stowage or fit, while a smaller size would risk binding or failing to carry the required load. So the twist shackle is 5/16 inch.
