While its possible the waste pump-out line on the boat is plugged, most pump-out problems can be traced to poor procedure. Instructions on the pump-out station-if provided at all-overlook key factors, probably because the bureaucrat who wrote them didnt actually understand the process. Here are some tips on doing it right.

Noise impacts individuals differently. If your sailing partner complains about a noise that doesn't really bother you, it might not necessarily something that they can simply get used to. You will have to address it through active sound reduction measures. There are three basic approaches to making your boat quieter. The first step is to use flexible mounts to isolate the vibrating machinery from the hull. These help prevent the transmission of vibration through the solid structure of the boat, and the consequent reverberation of hull sections that can act like amplifiers. Correcting any engine-shaft misalignment will certainly help. The next step is to surround the noise-producing machinery in a tight, insulated enclosure to reduce air-transmitted noise. The final step is to line enclosed living quarters, such as cabins, with sound-absorbent materials.
