Crafting the Base and Hull
Creating the Base
Begin by cutting two large rectangular pieces of cardboard for the base. The dimensions will depend on the desired size of the boat. Then, cut out several smaller rectangular pieces for the sides. Make sure the sides are high enough to provide adequate depth for the hull.
Constructing the Hull
To create the hull, you will need to curve the cardboard to form the shape of the boat. This can be done using a variety of methods. One option is to use a sharp knife to score the cardboard along the desired curves and then gently bend it into shape. Another method is to wet the cardboard and mold it using your hands. Once the desired shape is achieved, secure the edges of the hull with tape or glue.
Additional Tips for Constructing the Hull
Here are some additional tips to help you construct a sturdy and reliable hull:
- Use multiple layers of cardboard for increased strength.
- Reinforce the edges of the hull with duct tape or other strong adhesive.
- Apply a layer of waterproofing sealant to protect the hull from water damage.
- Consider adding a keel to enhance stability.
Shaping the Deck and Ribs
Crafting the Deck
The deck is the flat top of the boat that you will stand or sit on. To create the deck, start by drawing the desired outline on the cardboard sheet. Cut out this outline using a sharp craft knife or scissors. You can reinforce the deck by gluing on additional layers of cardboard or using a sturdy backing.
Fashioning the Ribs
The ribs are curved supports that give the boat its shape. They run from the bottom of the hull to the deck. To make the ribs, cut long strips of cardboard that are slightly curved. The length and curvature of the strips will vary depending on the size and shape of your boat. Gradually bend the strips and glue them to the inside of the hull, aligning them with the deck. If necessary, cut and glue additional strips to create a smooth, continuous shape for the ribs.
Securing the Ribs to the Deck
Once all the ribs are in place, they need to be secured to the deck. This can be done using glue, tape, or a combination of both. Apply a generous amount of adhesive along the top edge of each rib and press it firmly against the deck. Reinforce the connection by wrapping tape around the base of each rib and the deck. Ensure that all ribs are securely fastened for optimal stability.
Waterproofing and Sealing
The waterproofing of your cardboard boat is an essential step in ensuring its functionality and durability in the water. Several techniques can be employed to achieve this:

| Applying Waterproof Paint or Sealant | Durable, provides a smooth finish | Can be more expensive, requires time to apply and dry |
| Waxing | Adds additional protection, repels water | Can be less durable than other methods |
| Duct Tape Repair and Reinforcement | Versatile, can be used for repairs and customization | Not as waterproof as other methods |
Installing Rudder and Tiller
Cut Out the Parts
Start by cutting out the rudder and tiller from the cardboard. The rudder should be a rectangular shape, about 12 inches wide and 24 inches long. The tiller should be a long, narrow strip of cardboard, about 4 inches wide and 24 inches long.
Attach the Rudder to the Hull
Next, attach the rudder to the hull. You can do this by using duct tape or glue. Make sure that the rudder is securely attached so that it will not come off when you are sailing your boat.
Connect the Tiller to the Rudder
Once the rudder is attached to the hull, you can connect the tiller to the rudder. To do this, simply insert the end of the tiller into the hole in the rudder. You may need to use some glue or duct tape to secure the connection.
Install the Rudder and Tiller Assembly
Once the rudder and tiller are connected, you can install the assembly on your boat. To do this, simply insert the rudder and tiller into the opening in the stern of the boat. You may need to use some duct tape or glue to secure the assembly in place.
Test the Rudder and Tiller
Once the rudder and tiller are installed, you can test them to make sure that they are working properly. To do this, simply move the tiller back and forth. The rudder should move in response to the movement of the tiller.
