We all know how loud the diesels can get when cruising out to the fishing grounds. My son came up with a great idea. He went into the engine room on our 32 and had me close the hatch on him. He saw many gaps of light shinning thru where the hatch seals. We stopped at Home Depot and picked up some one sided foam insulation rolls. After adding the seal over the one installed by the factory we noticed a significant decrease in the noise level.
