Well boats usually do not blow up or catch fire from hydorgen leaking from batteries. It is usually from gasoline vapors or leaking propane. The plastic battery box is a corrosion / spill containment issue.   My Jaguar XJ8 L has the battery in the well sealed trunk of the vehicle, I have also

If you are using flooded lead acid cells, one thing to consider is the use of HydroCaps. These devices reduce both water consumption and gas generation. They are commonly used in both marine and solar power applications. I have used them in back up power applications and they work well as
