Last night my wife and I were sitting at the dinette table doing some computer work. The cabin was quite and we noticed a new noise that sounds like rice crispie treats snapping and crackling and popping. It was coming from the forward cabin. Upon inspection, we heard it the loudest under the step when we removed the cover to the step. This morning, the sound continues and could be heard through the night as we awake off and on. We're in the cockpit now emptying lazarettes and the same sound is heard on the port side of the boat in the lazarette as well as the center lazarette that holds our generator. We have a 2019 27ft Ranger Tug. We've cleaned out the c-strainers as well. The c-strainer did have some grime in it. I've taken a a picture of the water gauge to see if we notice a water loss later today. We're not sure what else to do. Any ideas for us?
 
When we were anchored in Florida waters several years ago we would also hear "snap and crack" noises from time to time. We learned, or were told, that these noises came from fish, shrimp, or some other sea creatures, in the water around our hull. Sounds likely. . . Slade and Susan Cargill
 
Hi gsc3,

Not sure what is happening there. All items that may make this kind of noise during the curing/manufacturing process (which still don't sound very much like this) will have been finished by now. So not sure what is happening there. As tugalong09 mentioned, it may be noise from outside the hull. Let us know if you have more information. Hope this helps.

Cheers,

Ralf
 
You might check the sonar transducer. My transducer makes more noise than it should. (Apparently because I inadvertently worked on it with the unit energiezed—a no no.)
