If it's bolt-on ballast, you will have occasional fairing and rust blister clean up if the ballast section is not properly sealed.
If it is, as I suspect it may be, encapsulated ballast (ie - the ballast is set into the molded hull/keel sections) then the potential for problems is compounded. If moisture ever gets into the ballast area, eg from a grounding, then it will fester in there, the iron will rust and expand which may cause damage (swelling and possible fracture) to the hull in that area.
Once this area has gotten wet it is difficult to fully drain and dry it out.
Other more qualified experts will be sure to expand on this.
