Ballast Ratio Meaning in Sailing

The ballast ratio is the percentage of a boat total weight made of ballast. This number helps sailors understand how stable or stiff a boat will be. A higher ratio usually means the boat can carry more sail in heavy winds. A naval architect calculates the ballast ratio to ensure the vessel meets safety standards. A boat with a forty percent ratio is generally considered very stable for ocean travel. This measurement affects how far the boat leans over when the wind blows hard. Sailors compare these ratios when choosing a boat for racing or for long cruising. Maintaining a good ratio is key to the performance and safety of the boat.
