How should the sea anchor be rigged?

Rigging the sea anchor at a 45-degree angle to the seas is beneficial because it helps to optimize the anchor's effectiveness in reducing the vessel's drift and provides better stability. When positioned this way, the sea anchor can effectively counteract the forces of the waves and wind, minimizing the impact of potentially dangerous conditions. This angle allows for an efficient balance between the drag created by the sea anchor and the forces acting on the vessel, thereby improving control and safety.

In contrast, rigging the sea anchor parallel to the boat's direction can lead to ineffective performance, as the anchor wouldn't create the necessary drag to stabilize the vessel. Setting it at a right angle to the waves could allow for some control, but it may not fully utilize the anchor's potential to mitigate the vessel's motion in more varied sea conditions. Similarly, positioning the sea anchor perpendicular to the wind direction could lead to unpredictable forces acting on the boat, which could exacerbate instability rather than enhance it. Therefore, the 45-degree angle is strategically optimum for usable control and safety in turbulent sea states.
