I've done 2 dives on the Chikuzen and it is a great dive. In settled conditions there is no current and there has always been an abundance of fish life around the wreck. I haven't been back since Irma, but I haven't heard anything about the site being changed by the hurricane. There is one mooring ball there, but if a commercial dive vessel shows up you will need to relinquish it immediately. This means having someone on board who can operate the boat while the others dive.
