Not too many people around here are worrying about the conversion.
The americans when Australia
were happy as is.
You might be too.
The only think you don't get would be your electric
If you decide to change over then the wiring
in your boat is all the same 110 and 220 (no matter what people say) as the production method calls for it.
So its just a change of the battery charger
The power socket can just use a pin converter so you don't need to replace them.
We don't use the sockets in port anyway. We have bought a fan and are running it directly off the wharf from a double adapter
*air con etc would be differnt.
