In regards to your question; ballast in a lead keel boat is the weight of the keel. In boats with water or movable ballast systems it may be a combination of ballast types but in terms of specs for a Cal 2-25 it is simply the mass of lead.
If you add lots of "stuff" low in the boat (water, batteries, fuel, provisions) it also adds a bit to the "ballast" but not nearly as much righting moment as the keel itself).
What did I win??
