Fitting 24v bulbs into 12v fittings won't be a problem as long as the bulbs are physically the same. There are electronics that will work on 12&24V, Much of the Raymarine range is dual voltage.
Assuming that you have 2x12V batteries on the boat in series to give 24V, you could take a feed from one, to supply 12V to the electronics.
