Balia had a fitting a bit like that in her foredeck. Almost like a bayonet light fitting but not quite in her case. In fact the way it's configured I've never been able to work out what the heck it was for. I suspect a removable bowsprit as the stem fitting has a round thing in it, cranse iron? And this fitting was directly behind that. But it's not quite like a bayonet fitting. Weird.
