The Ballast to Displacement Ratio Explained (with Formula)
The formula for this ratio is: ballast displacement ratio = ballast / displacement. In other words, it tells you what percentage of the sailboat's weight is in the ballast. The average value is between 0.35 and 0.45 for cruising boats. This means that on average, 35-45% of the weight of a cruising boat will be carried in the keel ballast.
