Why is slow rolling considered dangerous on a vessel?

Slow rolling is considered dangerous on a vessel primarily because it might cause capsizing. When a vessel experiences slow rolling, it undergoes a gentle and prolonged rolling motion which can lead to instability. This rolling motion can create a situation where the vessel's center of gravity shifts, especially if the roll exceeds certain limits. If the roll remains uncontrolled for an extended period, the vessel could potentially reach a critical angle of heel, leading to capsizing.

Maintaining proper stability is crucial for safer vessel operation. Any condition that disrupts this stability can pose significant risks, particularly in adverse weather conditions or when navigating through challenging waters. Therefore, understanding the mechanics of slow rolling and its potential to induce a hazardous situation is essential for ensuring the safety of the crew and the vessel itself.
