When do most enclosed lifeboats or covered survival capsules automatically right themselves after capsizing?

The correct understanding here is that most enclosed lifeboats or covered survival capsules are designed to right themselves after capsizing when all passengers are strapped in. The mechanism relies on the weight distribution and the center of gravity being affected by the occupants being securely fastened within. When fully loaded and passengers are properly strapped in, the enclosed lifeboat can utilize its design to effectively regain its upright position.

The other possibilities do not accurately reflect the functioning of these safety devices. For example, the improvement of weather conditions wouldn’t trigger an automatic righting mechanism since lifeboats are built to operate based on the physics of buoyancy and center of gravity rather than external conditions. Similarly, the stabilization of the vessel itself wouldn't directly influence the lifeboat's ability to right itself; it depends on the dynamics within the lifeboat rather than the situation of the primary vessel. Immediate righting upon capsizing does not apply because the mechanics are reliant on the factors associated with the occupants and their secured positions.
