Tim:
A lot has changed since 1972.
According to the USCG, the termimals on your batteries should be covered to avoid a short circuit and fire.
Also they should not be above or below any part of the fuel system and must be fastened securely to the boat.
Here's the regulation:

Better yet, battery boxes from Wallmart ($7.00) would cover the terminals and catch any spilled acid.
Last season, one of my batteries self-destructed and the case cracked. The acid spill was contained by the box.
As added protection, I sprinkle a box of baking powder in each battery box to neutralize the acid if it spills. It seemed to work.
