There are many times I wish I had gone 24V.

Another consideration, filament lamps.

The lower the voltage, the larger the filament,

The larger the filament, the less likely it will be affection by vibration.

6 VDC is better for filament lamps on a boat, but you live with 12 VDC.

Way back when, each pilot light used in machine control panels contained
it's own small transformer.

115VAC input, but the lamp itself was 6 VAC.

A Pilot light that doesn't work is a real PITA.

As far as 12 v 24 is concerned, if 24 VDC is good, 48 VDC is better. If
48VDC is good, etc, etc.

Higher distribution voltages best serve large loads like a windlass or a bow
thruster; however, high mechanical power DC motors are a real headache.

Basic reason I'm installing an engine driven hydraulic system to handle the
bow thruster and windlass.
