The primary requirement is that it should be water resistant and must not let the water inside the boat. Numerous methods are available on the internet but the safer one is sealing the custom cardboard box with waterproof liquid, and every bit of the ship must be covered with it but this may also be an expensive method. Duct tapers or clear packing tape can also be used for this purpose. Some of the paints in the market such as enamels, acrylic and latex and some types of glue can also be a good insulator for water.
Follow specific rules while making a boat from cardboard
Following rules is essential in all handicrafts but making the craft from cardboard boats it is crucial because there is a risk of drowning if not assembled correctly. Cardboard is light material, and that is why the boat floats, therefore, it must be entirely made of same cardboard. Other significant ingredients are duct tape and polyurethane that helps in making the boat waterproof. Carpet tubes can be used to make the ship more efficient along with sturdy paddles that will, of course, assist in the rowing process. The cardboard you use must come directly from a packaging box, not the pretreated one because then the boat may feel shaky.
Stay right and do not use other material such as plastic, wood or metal. Duct tape can be an essential part, but the whole boat should not be wrapped in it or plastic sheet. You can use other solutions to waterproof it such as acrylic paints and varnish. Make sure that the boat also looks beautiful without losing the efficiency because embellishments increase the value of your effort. The people in the boat must consider an escape route and wear required safety gear.
Material selection is essential
There is no doubt in that aspect because the material is the fundamental standpoint of where to start making cardboard boats. The best stuff for this adventure is the corrugated cardboard because it provides strength and innovative structures. These boxes can be attained through various products and stores such as furniture showrooms and grocery stores.
Draw a basic design layout
A well-explained sketch of drawings could help plan and construct boats with the help of cardboard. A haphazard beginning will result in deformed product and efficient sailing device. Keep in mind the dimensions of places the ship will go and the amount of weight it should carry. Other significant parts of this experience include the importance of the boat itself, quality of cardboard, depth of water and length of voyage.
Remember the rules of science while designing
Science plays a significant role in the construction of every structure, and the best part about these rules is that they are entertaining to learn. The rule of displacement means that when you put the boat in water how much will it go down in water and what part will remain afloat. If the boar is more extensive, it will float well and get adequate speed from the shape. According to experts, the boats having less length make it hard to remain straight on the water. Another problem that you may face is about speed because longer boats are faster but also challenging to row and turn when required.
Be creative in decorating your boat
Incorporate creative ideas so that you can deal with issues efficiently and in an artistic manner. The designs and decorations must not interfere with speed and buoyancy. Use beautiful colored paper to put stencil cut designs on the boat. Get a complete estimate of the material you have and the plan it intelligently so that things look and work excellently.
First, use tape to cover every edge of the cardboard so that it does not soak up water. Carpet tubes are best for outlining boats made of cardboard. Apply small cuts on the lines where cardboard is bent to form the folds. Use glue that is usually applied to wood or paper to insulate the carton from the water.
