Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Sailing ballast?
Summarize this article for a 10 years old
Ballast is used in ships to provide moment to resist the lateral forces on the hull. Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel capsizing. If a sailing vessel needs to voyage without cargo, then ballast of little or no value will be loaded to keep the vessel upright. Some or all of this ballast will then be discarded when cargo is loaded.
