Mercury was used by Cousteau for trimming his soucoup because of the
liquid metal's high density. I would expect mercury to be very
expensive and hard to get now.
Likewise, the Bathyscaphe Trieste used gasoline in her float because
it is a lighter--than-water liquid. It worked, but I don't think you'd
get away with that technique now because of environmental hazards.
Given our current knowledge, why ignore the fact that there are better
choices with fewer drawbacks than mercury for ballast and gasoline for
flotation?
My 2 cents paid in full.

I'll suffice to say that, for me, it
comes down to the question of whether the design advantage is worth it
when balanced against the potential and likely event that an environmental
government agency (DEQ, Coast Guard) and/or activist group(s) finds out
you're carrying even trim-ballast-quantity of mercury in State or Federal
waters or over roads on a trailer (DOT governs transportation of toxic
& hazardous materials) ... shudder. Not only that but I'd feel
like ... if I actually spilled. Not for me.
