In the last lesson, we discussed the ideas of using flat-hulled boats and round with keel hull boats for balloon-powered boats. These designs were explored as options for maximizing efficiency and speed in a balloon-powered boat.
For my potential design, I would like to create a round with keel hull boat. This design allows for better maneuverability and stability in the water. It also helps with reducing drag and increasing speed.
To modify the design, I plan to add a smaller, removable keel at the bottom of the boat to ensure better stability and keel effect. I will also make sure that the round shape of the hull is streamlined to minimize the resistance of water.
The materials I have readily available are cardboard, duct tape, a few small wooden dowels, a thin plastic sheet, a balloon, and a pair of scissors.
To build my boat, I will need the following equipment:
1. Scissors for cutting the cardboard and plastic sheet.
2. Duct tape to securely connect all the components.
3. A ruler or any straight edge to help create straight lines for cutting.
4. A marker or pen to mark measurements on the materials.
Using these materials and equipment, I will construct a round with keel hull boat by cutting out circular shapes from the cardboard for the top and bottom of the boat. I will attach the two circular pieces together using adhesive and tape to create the rounded shape. Then, I will cut a small rectangular keel shape from the cardboard and attach it underneath the bottom of the boat, ensuring it is securely placed in the center.
To ensure the boat can move forward, I will attach a small wooden dowel to the rear of the boat, creating a place for the balloon to be attached. The wooden dowel will act as a guide for the balloon's propulsion.
Once the basic structure is ready, I will cover the boat with a thin plastic sheet to make it more waterproof and reduce friction with the water.
Overall, this design aims to combine the round with keel hull concept with the available materials to create a lightweight and streamlined boat for efficient balloon-powered propulsion.
