Apparently there are apps that help to identity things by taking a picture. You may want to try that but I suspect this is so odd it may not be recognized. btw, is it solid or can it be compressed?
I don't know what it did on your boat, but I recognize that thing from inside a telescoping closet pole or telescoping (spring-loaded) shower rod, or curtain rod.
Nope, no sliding doors or cabinet doors. Nothing like that behind cabinet drawers either. I'm stumped. And as I said it just appeared on the floor in the AM. Weird for sure.
I think it ‘lives‘ between your ensuite bathroom door and the set of cupboards which the door latches onto when it is open. Without that squishy spring thing there, that door will rattle on the hook latch with the slightest ocean movement.
I say this because my GB does not have that squishy thing, and if I leave the ensuite door latched open at night I have to stuff a pair of socks between the door and the cupboard to stop the rattle.
Just a thought.
Hamish.
Well you have succeeded!
