For open lifeboats, what kind of release lever is utilized?

Open lifeboats use a lever-operated, mechanical release known as the Rottmer releasing gear. The operator moves the lever, which drives a locking cam or pin in the release mechanism, freeing the lifeboat from its cradle on the davit so it can be lowered. This setup is favored because it works without any power source—no electricity or hydraulics needed—making the release quick and reliable even in challenging conditions. Electric or hydraulic releases rely on power and can fail if systems are damaged, and a manual chain release is another approach but the Rottmer lever provides straightforward, robust operation specifically suited to open lifeboats.
