How many degrees is the lip required on the outboard side of the lifeboat cradle for standard Navy lifeboat stowage?

The correct answer indicates that the lip required on the outboard side of the lifeboat cradle for standard Navy lifeboat stowage is 15 degrees. This specification is important for ensuring that the lifeboat is securely stowed and can be safely launched when needed. A 15-degree lip helps accommodate the natural motion of the vessel and ensures that the lifeboat remains in position during rough sea conditions, preventing it from shifting or becoming dislodged. This angle aids in the proper alignment and stability of the lifeboat cradle, which is crucial for operational readiness and the safety of personnel.

In contrast, the other degree options would not meet the established standards for lifeboat cradle design, either being too steep or too shallow, which could compromise stowage integrity and impact the lifeboat's ease of deployment in an emergency.
