Boat Hull Designs - Make Sure You Follow the Rules When building a boat much importance should be given to the hull because this is the part of the boat that will be in contact with the water and hence perfect buoyancy force should be allowed to the hull. While designing the hull care should be taken to see whether the hull is accurate enough to float the boat or stable the boat in water. It should also maintain the right buoyancy on the right side of the boat. If this is not there then the boat would begin to sink much to your dismay. So you need to follow a set of rules when building the hull of your boat. Strength of the hull is very essential. It should be strong enough to come in contact with strong winds and rough waters too. So if you are a novice at boat building you need to choose hulls that are easy to build but at the same time not weak. They should be built with metal that is durable and safe. If your hull has these features then it is considered near to perfect. While building the hull of any boat care should be taken to see that the center of buoyancy is fixed halfway between the stern and bows. You should keep the buoyant at the right point which ensures that the boat does not topple over or become unbalanced by waves easily. All hulls have curves in their structure, so when this curving is being negotiated the degree of curving should be accurate and equal to the curvature of the base of the boat. By doing this you are creating an equal pressure on all parts of the boat. This helps the boat to be perfectly smooth and the jerk is reduced. In the case of a ballasted boat that you are building you should make sure the weight is always maintained between 40 and 50% more than the weight of the ballast. Or you can build a boat that is designed to hold the ballast below the water line all the time. If you will agree, the hull is the most important part of a boat and special care and attention should be taken to use the right material, the right weight and size to match each other and most of all, the stern should be fixed at the right place. If you feel unconfident about the rules to follow while building the hull you could safely download 3D boat design software from the internet and follow the step by step user friendly manual which provides you with weight, size and design with which you can never go wrong in building a perfect hull for the perfect dream boat.
