@freemo When I used to teach lab it wasn't, but I honestly can't recall it's exactly Ksp. I'm fairly certain that *technically* all "insoluble salts" are partially soluble to some degree, but functionally I think your boat would be fine...as long as you can find a way to make silver chloride crystals large enough that it'll stay in one piece xD

@freemo Oh actually it's in the near micromolar solubility so you're fine.

@johnabs just enough solubility to ensure I dont get barnicles. The salt would very slowly dissolve and they would fall off over time :)

:The hard part is getting the maintanence "Hey my boats hull is getting kinda thin, would you mind adding a few new layers of salt to it, thanks"...
