I'm hoping someone here has experienced something similar and has some advice
We've noticed a periodic loud BANG on our 2005 Saga 43. It sounds low in the boat
, and as if the hull
was stuck hard by something like a mooring
ball or log. It is only a single
bang never multiple closely timed together. My wife pointed out that it seems to correspond with flushing
or using the sink in the head
. At first I thought she was crazy, but it does seem like it may be correlated. It happens so sporadically though its hard to track. Could this be some sort of water
hammer? Or maybe somehow the tank is building a vacuum until it pops back into shape and equalizes, and that reverberates through the hull
We have two 65 gallon plastic tanks
, one under the port and one under the starboard settee.
Thank you for any ideas or advice
on how to best investigate further!
