Not something I lay awake at night thinking about either. It does look like they use something to fill the area next to the tank. I'm guessing that any water that makes it over those cut outs will exit the same way it came in.

Seal the bilge access hatches some leak water on top o tanks. Also, some tanks are foamed in place, so keep the bilge dry. You can also paint the top o tank with aluminum rich paint ( Rust Oleum Professional Alum pnt):

Just waht i noticed and As there are ni pics of deck, some of the things i noticed may not be true!
The pictures of the boat in construction above look somehow "scary" to me:
- tank is not painted
- tank is glassed in and be under console and foredeck and this will lead to a major PITA to pull tank
- not visible if PU foam is used to fill space between tank and bulkheads
- tank will
- if tank has a flat bottom he suppose to be avove standing water inside tank compartment (even if it should be watertight(what never happen on a boat))
- If the tank has a triangular bottom and there is water inside this compartment then he will sit in the water
- pipe going from bow to stern below the tank looks small to me, i have a similar pipe in my panga and she frequently clogs

I had the Florida marine Tanks built tank of my Boston Whaler 23 Outrage sitting in the bilge water as boat was sternheavy due twin 4-strokes and lower stern side got badly pitted till leaking gas in bilge.
This day i was smelling the fuel as battery switches are in the bilge area so i could leave them switched off and have the boat pulled and brought to ship yard to dump the gas and install new tank.
