1) sculp xps foam/balsa plywood to the desire hull of hull of the ship.

2)cut the fiberglass to cover the sculpt shape around the foam

3)pour resin and with for it to dry

4)sand it down slowly increasing the grit

5) test and modify

the wind will help cause when we are going to test it in the pool the teacher will put like a fan at the front which I suppose helps us steer the boat

1. Strength & Stability – The keel supports the framework of the boat and keeps it balanced in the water, preventing it from tipping over.

2. Directional Control – On sailboats, the keel also stops the boat from sliding sideways when the wind pushes against the sails. This helps us steer and maintain our course.

For our sailboat project, the keel is crucial because it will:

• Keep our model steady in the water.

• Show how real sailboats resist the force of the wind.

• Demonstrate the engineering principle that stability comes from having weight low down (like a counterbalance).

Without the keel, our sailboat would easily capsize or drift sideways instead of moving forward. By including it, we’re making our design more realistic and learning how sailors use physics to their advantage.
