Hi There,
>
> I am a veteran Submariner. I do remember from my training courses many
> years ago, that in the past, some submarines had a dropping keel. A certain part of the keel was detachable and in cases of emergency this part of the keel could be dropped and make the submarine light so that she would gain positive
> buoyancy and she would float to surface.
> Pertaining this I have a few questions:
>
> * Do I remember correctly?
> * What type of boats had this arrangement?
> * Is it possible to get some technical details how was it designed to work?
> * Was it possible to release this part of the keel even when the boat
> was bottoming (being in the position of sitting on the bottom of the
> sea)?
>
> Many thanks,
>
