The noise issue makes sense. This week, I began doing research on insulating my engine compartment for noise. Your post reminds me of the noise I hear in the bow area, fiberglass slapping the water when underway. I am do have access to the hull in various locations in the bow area through compartments and am thinking now of adding sound dampening insulation to this area as well. Noise is fatiguing for sure, the quieter the better especially when trying to sleep.
I have found several places on line that sell, sound insulation. Even our own Fisheries Supply in Seattle sells it.
I would think it better to insulate with bow area with 1" marine sound insulations to the entire compartment if you can get to it.
I think that is what I am going to do.
Good use with it, let us know how it works out.
