Spacious cabins, high ceilings, and ample storage space create a more pleasant boating experience. These features stand out. But to learn how well the boat is insulated against noise and vibration, you must use and observe the vessel. This use and observation should be prolonged because every boat behaves differently and has various noise and vibration levels while at anchor, at cruise speed, and at full throttle. However, if there is no possibility to test the boat in this way, one can also look at the specifications, in particular at the locations, thickness, and type of the insulating material. Whether you are looking to purchase or build your own boat, this article will tell you what is important to prevent onboard noise and vibration.
