I got an email from my marina service department that says "No vents in battery box compartment, this is a safety of vessel and crew issue"  and "There is no fusing at either the charger or the alternator."  A few months ago, they did a lot of work to the battery compartment as the fiberglass had corroded and various bolts were corroded (such as the ones that hold the chart table seat and the ones that hold the cocktail table bracket).  I spent a lot of money having it rebuilt, replacing batteries and cables.  Other than replacing batteries periodically, the compartment was as it came from the factory in 1995.  My recollection is that there were fuses in the compartment that I assumed fused the connection between the charger(s) and the battery. 

Where would these fuses ordinarily be located?  Was the battery compartment vented when it came from Catalina?  Do you agree that the compartment should be vented?  How?

I have a 95 C36 mkII, hull 1469.

Thanks for your ideas
