It's worth mentioning that speaking with the yacht builders, not one uses a floating (isolated) DC system. Why?
Because:
- the standards (ISO etc) mandate it; and
- they dont want to get sued.
In a boat, an earthed system is MUCH safer than isolated. Maybe we should buy aircraft. Aircraft get away with it because the systems are in a controlled environment, they are rigorously maintained, stuff doesn't get added by twisting it into the closest power wire and.... they don't float in water.
Actually that's a bit harsh. They might float...just not for very long
Lightning protection is a good case in point. Marine lightning protection systems require a grounded path to the water to either (1) safely conduct and dissipate the massive energy of a direct strike, or (2) reduce the risk of a strike by bleeding off static charge to minimize the formation of upward streamers.

Although the lightning protection system may be implemented as a separate grounded system.
