Generally alloys can selectively corrode, so with a combination of gold and iron the iron may still be attacked. But certainly some gold alloys provide improved hardness without being very vulnerable.
For a boat the gold coating would need to include all metal parts in contact with the water (rudder pins, prop shaft, etc) and it would be an interesting experiment to learn whether it really prevents fouling (I can imagine that wear and damage to the coating might provide cervices for growth to anchor)

Presumably barnacles would still stick to it though?
I'm convinced the great filter has something to do with the availability of gold to a species. There are all manner of gold based alloys that we haven't researched and There are all sorts of technological innovations locked away from us simply because gold is too expensive.
case in point, a boat hull coated in a gold alloy could be non reactive. no more need for antifouling paint or sacrificial anodes.
