Sure, but they're not really an aftermarket add-on.

And it's not foolproof either, since grids & bulkhead tabbing
occasionally pop loose when the boat is sailed hard (or if your boat was
one of those Monday morning jobs).
You could buy structural panels, tab them in on
both sides. Similarly with baffles. Closing off
the top would be easy too and just as easy to
cut in inspection ports--or even cut off completely,
and reglass later, for service.
Why buy structural panels, I can mold them myself. But this is likely to
be a lot more work (a whole lot more!) and require more open access to
the space.
Another advantage would be you could fair in
the inside so that there is a slope to carry debris
to the drain fitting.
True... put in a little window for visual inspection too.
Actually, I should build the whole boat myself! Then every part of it
would be PERFECT... wouldn't Bubbles be jealous!
