The Irwin 54 is a 54.0ft staysail ketch designed by Ted Irwin and built in fiberglass by Irwin Yachts. Based on the design ratios, the theoretical sailing characteristics of the Irwin 54 are:
It's important to note that these ratios are theoretical and have their limitations. For instance, the Ballast/Displacement Ratio doesn't consider the location of the ballast, which can significantly impact the boat's stability.
Similarly, Ted Brewer's Comfort Ratio favors heavy displacement, narrow-beamed vessels with long overhangs. Therefore, today's light-displacement, beamy cruisers with plumb bows might not score well for crew comfort according to this ratio, even though they may well have bluewater capability.
