The correct answer is D) underway with the wind 30° on the bow. When evacuating a seaman by helicopter lift, the vessel should be underway with the wind 30° on the bow. This allows the helicopter to approach the vessel from the proper angle, with the wind coming from the bow, which provides the best conditions for a safe and stable lift. The vessel being underway also helps to minimize the effects of wind and waves on the lift operation. The other options are incorrect because: A) having the vessel underway on a course to provide no apparent wind would not provide the necessary stability and control for the helicopter lift; B) having the vessel stopped with the wind on the beam would create challenging wind conditions for the helicopter approach; and C) having the vessel stopped with the wind dead ahead would not allow for the optimal 30-degree angle of approach.
