There are likely many of us in the house
Consider us a companion of the mouse

Captains who encounter a string of bad luck
Could end up deserted on one of me stuck

But whether or not they will stay afloat
When I am depressed you will make a note

"Off me" doesn't produce a pleasant sound
For propagation I spin to the ground

If you'd like to get in, then give me a turn
A mystery's answer with me you will learn

I'm often associated with a ring
Although I'm multi-faceted in meaning


What am I?
