The owner of the boat wanted to block out the noise of the huge powered engine. We anaylized the situation together and found out the most effective way to block out those noises.
We used Second Skin's Damplifier Pro on the 1st layer, Luxury Liner Pro for the 2nd layer and Spectrum Sludge for the 3rd layer. We also used Heatwave Pro on some areas which was closest to the engine to dissipate some heat.
Here are some of the pictures on how it was done.
