Frequently Asked Questions
What is the Crouch formula?
The Crouch formula is a well-established naval architecture estimate: Speed (mph) = sqrt(Horsepower / Displacement) x C, where C is an empirical constant that depends on hull design -- lower for heavier cruising hulls, higher for lightweight racing hulls.
