The reactor itself does not make a lot of sound when operating. Nuclear fission is silent, but moving water in the core (in a pressurized water reactor) might be heard as it circulates. But it would not be easy to put your ear to the reactor vessel as radiation levels would be very high and the vessel would be very hot. Certainly the pumps that are running to circulate coolant will be audible.
If the water and your vessel permit it, you'd be wise to anchor and ride out the storm. If you are in open water, a sea anchor can stabilize your ship bow into the wind, and reduce your leeway.
A submarine is a vessel that can travel both on the surface and under the water.

Inland water ways or rivers. During the Vietnam War the US Navy operated a "Brown Water Navy" which basically meant a riverine force. One type of vessel operating in that war was the 50' aluminum hulled "Swift Boat."
A reactor vessel in a boiling water reactor is approximately 300 tons.
Arrival draft means the deepness of the vessel under water when the cargo is loaded in the vessel, and departure draft means the deepness of the vessel under water after the cargo is discharged fully or partially.
When a vessel travels through the water it raises or sinks slightly relative to when it is not moving. This change in how the vessel sits in the water at varying speeds is referred to as the Settlement and Squat.
i would assume that a pwc is in the personal water craft class. This is incorrect. PWC is a Class A water vessel.
