You want the hull to ride at the right attitude so it handles and tracks better.

How to design a yacht hull. My first yacht was a Graham Bantock Italico second hand but fully set up and ready to race. Displacement boats can be very fuel efficient certainly much more efficient than planning hulls. Designing the half hull model in After some fiddling trying to get the screen capture software to work i made this.

The best would be if you could design boat hulls that will hold the ballast below the waterline at all times. But for modelling a. Designers found that by adding a chine flat on each side they could increase the lift of the hulls.

We design the underwater volume of a hull to be distributed in a way that matches the optimal fore and aft center of gravity of the assembled boat plus her occupants and gear. This center of buoyancy is the volumetric center of the shape of the underwater part of the hull. Boats with planing hulls tend to skim across the surface of the water as much as possible rather than displacing high quantities of water.

In the simplest design the chine is simply a corner on each side of the hull that has no effect on performance or handling. Building boat hulls is not a big headache but these basic points have to be kept in mind if you want a perfect streamlined hull. 11 and above preferably from 2 and up.

Engine room forms a significant part of hull volume up to 30-40 per cent Weight matters powerweight ratio is critical. Say you are designing a ballasted boat. This is the phase when the look of the yacht is born.

Because there is such a diversity in types of hulls design styles and an ever-expanding array of new construction materials it is difficult for surveyors. You can model a hull simply lofting the sectional curves curves of the body plan. Here is an attempt at demystify model boat hull design and construction.
