This historic park has a variety of ships. We focused mainly on the Balclutha and Eureka, being the largest two. The Balclutha has claims of a haunting from seamen who died on ship and photos of orbs have been taken there. Unfortunately, this location is in a very touristy area and the ships themselves are relatively closed off, even though you are free to tour by yourself
There was no EMF activity at all. The feeling on board the ships seemed open and peaceful. We did notice a lot of dust, which would easily account for the orb photos others have taken.
