Hi Bill,
For any high voltage (greater than 48V nominal) installation, you should look at ABYC publication TE-30 - ELECTRIC PROPULSION SYSTEMS, which is an addendum to the regular ABYC E11, AC and DC Electrical Systems on Boats that covers regular boat electrical systems.
The additional requirements for high voltage systems are not excessive, but they do add come complexity and cost to the design and execution of a safe marine DC system that is higher than 50V.
Fair winds,
Eric
