Why do hulls of the same length, beam, weight and power vary so in performance?
Here the effect of an engineered design is realized. The difference between a boat designed by a qualified naval architect and one built by backyard techniques may be many miles per hour. Boat design is both a science and a skill which has evolved over many years. The designer must be cognizant of the effect of weight, weight distribution, deadrise and other hull characteristics which can affect overall performance. Otherwise, a poor performing boat results.
