Materials Needed:
Two empty plastic bottles (500ml or similar size, same type recommended) Balsa wood or stiff cardboard (for the deck and mast) Strong glue (waterproof recommended) Duct tape or waterproof tape Scissors or a craft knife Ruler or measuring tape Pencil or marker String or twine (for rigging) Small piece of fabric (for the sail, optional)
Step 1: Preparing the Hulls
First, clean and dry your two plastic bottles thoroughly. Ensure they are free of any residue or moisture. This will allow the glue and tape to adhere properly.

Step 2: Cutting and Shaping the Deck
Using the ruler and pencil, measure and cut a piece of balsa wood or cardboard to form the deck. The deck should be long enough to span the two bottles with some overhang and wide enough to provide a stable platform. The exact dimensions will depend on the size of your bottles. Consider shaping the front of the deck into a pointed or curved shape for better aerodynamics.

Step 3: Attaching the Hulls to the Deck
Apply a generous amount of glue to the top of each bottle where the deck will rest. Carefully position the deck onto the bottles, ensuring equal spacing between the bottles and the deck's edges. Use duct tape or waterproof tape to reinforce the bond, wrapping it securely around the bottles and the deck. Allow the glue to dry completely, following the glue manufacturer's instructions.

Step 4: Creating and Attaching the Mast
Cut a piece of balsa wood or cardboard to create the mast. The height of the mast will determine the size of your sail, so choose accordingly. Glue the mast to the center of the deck, allowing it to stand upright. Reinforce the base of the mast with extra glue and tape for stability. If using cardboard, consider laminating two or three pieces together for added strength.

Step 5: Making and Attaching the Sail (Optional)
Cut a piece of fabric into a triangular shape for the sail. The size of the sail should correspond to the height of your mast. Punch small holes along the edges of the sail. Use string or twine to attach the sail to the mast, threading the string through the holes and tying it securely. You can experiment with different sail shapes and sizes to optimize performance.

Step 6: Adding Rigging (Optional)
For a more realistic look and improved stability, add rigging to your catamaran. Use string or twine to create lines that run from the top of the mast to the deck, providing support and tension. You can also add a "boom" (a horizontal spar) to the base of the sail, attached with string, to help control its shape.

Step 7: Final Touches and Testing
Inspect your catamaran carefully, ensuring that all parts are securely attached. Reinforce any weak points with additional glue or tape. Once you are satisfied with the construction, test your catamaran in a bathtub or pool. Observe its buoyancy and stability. Make any necessary adjustments to improve its performance.
