I used the West Marine sound insulation kit that included the foil covered foam with a high density base. The sound attenuation was noticeable but nobody has ever asked if the engine was on or off.
I think of sound as light. If the boat interior was dark and you turned on a bright light inside the engine space the places you can see light are where to concentrate the insulation. As to going without, personal preference and how you use the boat make a big difference. If rarely using the engine or only racing the extra weight and cost may not pay off. For us and the way we use Calypso in the PNW we may use the auxiliary power for 6 to 8 hours at a time, sometimes with an off watch sleeping. The extra insulation coat was worth it.

I have replaced the old, crumbling sound insulation in the accessible parts of my engine compartment with new sound insulation from West Marine. However, there is almost no room on either side of my Yanmar in my 30 MKII. Getting new insulation in along the sides is going to be very difficult. I am contemplating just taking out the old insulation from the sides of the engine compartment and going without. Does anyone think this would be a big mistake?
