Nope!

Which I had niticed the smallhole in the bottom of the crossmember before it hit the water as well.

The small hole is deliberate. Even if you don't dunk your trailer water would accumulate inside via condensation without the hole to allow it to breathe/drain.

anything that gets galvanised has drain/vent holes in any enclosed sections, considerable explosion risk otherwise
