I am currently on an Island packet
sailboat at anchor
in an area with strong current
and tide shift. I just noticed this evening there is a soft rhythmic knocking coming from somewhere on the boat...I can't pinpoint its location it sound like it's everywhere and nowhere. But it's continuous. Every few seconds it knocks 5 times then stops for a few seconds and starts up again.
I don't know if it's something on the deck( though I have checked all rigging
and nothing that looks or sounds like this.) I live aboard my boat so am very attune to her sounds. I don't think it's anything on the engine
, though I have heard prop shaft could cause something tho I'm not sure that's it either...maybe anchor
chain ( though I doubt it). It almost reminds me of a woodpecker
Maybe a ghost
Any thoughts or if you have ever experienced this ? Much appreciated!
Cut a piece of hardwood about a 1" x 1" x 1' long. A piece of dowel or broom handle will do.
Hold it to your ear and then touch it to various parts
of the boat as you move for and aft and side to side. When you near the culprit, the sound will be much sharper and louder.
Give a special look at anything that hangs or swings/rolls. (Closets, wet locker, gimballed lights, hammocks/canned foods, candles, wine bottles, tools, etc.)
