12 and 24 volts systems

Hello, anybody out there could give some advise ,my boat is a Nicholson 44 and has 24 volts system , in the US 12 volts eletronics is more available ,so I was thinking to have bouth systems,can I run 3 batteries banks as (2 )24 volts and one 12 volts ? or is better to stick to one system ? Tks
The reason is I just bought a windlass horizon 1500 simpson lawrence (ebay)and is 12 volts and I can't return it so maybe I could use a 12 volts batteries bank just for the windlass and other electronics. and keep the 24 volts as the house bank.:confused:

The problem with installing a 12 VDC system is the wiring is often undersized for a 12 VDC system, which has higher amperages than a 24 VDC system. I would recommend you get a 24 VDC to 12 VDC converter that can handle the amperage draw of your windlass and just leave the boat wired for 24 VDC.

What might be a good compromise is to get a smaller DC-to-DC converter and install a windlass battery up near the anchor locker. :) Then use the smaller DC-to-DC converter to power a charger to keep the 12 VDC windlass battery charged.

There is an advantage as well with the battery for the windlass-- close to the anchor locker, less amperage draw for the "horsepower" the windlass needs-- also always ready and fully charged no matter the condition of the rest of the system provided ample charger is installed--- always nice to be able to "up anchor" quickly in event of foul weather, bad company, etc etc
