Design That Perfect Hull Modern Era boat building is a highly professional and skilled job involving precision engineering. But you will be surprised to know that it is one of the oldest forms of engineering, beginning with the ordinary rowing boat to the huge merchant vessels and aircraft carriers sailing the high seas today; and the hull is the most critical part on which the entire structure is kept afloat. The hull being the basic structure of a boat, certain fundamental rules are to be followed while designing to provide stability to the boat and keep it afloat. Designers have to bear in mind to make the hull strong and simple with the buoyant center fixed at the right point ensuring the boat doesn’t get imbalanced by waves and topple over. The other important aspect is curving. Proper curving implies, the degree of curving that is being integrated at the sides of the boat is equal to the curvature of the base of the boat. This ensures equal pressure of water on all sides of the boat for a streamlined, smooth and jerk-free sailing. The above facts enable you to design hulls for Ballasted boat, Clinker-on-frame watercraft or Racer boats. For a ballasted boat, the weight of the ballast placed inside should not exceed 50% of the upward thrust of water on all sides of the boat. It should be enough to dip the boat inside water and provide stability. For clinker-on-frame watercraft, you have to make three stakes of separation in between the joints of the hull to avoid disaster. Racer boat hulls are to be designed differently considering the ‘prismatic coefficient’. The prismatic coefficient is the measure of rate at which the cross-sectional area of the vessel changes. Finally, to design a perfect hull for your dreamboat you can avail 3D boat design software; which is quite affordable, easy and flexible to use.
