Reliable lifeboat hooks are important for ensuring that your lifeboat won't launch before you're good and ready. Fear of hook failures has often held crews back from performing necessary drills, and the reputation of lifeboats and rescue craft as a reliable safety measure has suffered.
But with the right hook design, you and your crew don't have to worry.
