Why all this ranting over a proven fact that drawing 12V off of one battery
of a 24V bank is not a good idea? A 40 amp 24/12 DC/DC converter capable
of running all the electronics on the boat can be bought for the price of a
couple of golf cart batteries.

This is nonsense!

I have a 24v electrical set up on my boat, but need a 12v supply for my VHF
(amongst other things). Is there any reason why I can't just run a 12v
supply from just one of a pair of batteries, or do I need to use a 24v/12v
converter. I release this will draw charge from just one battery , but
won't the other just top it up and there by drain them both equally
Thanks
