Influence on my choices.

After researching on The hulls, we decided what we will use. We knew that:

• Flat bottomed boat works well in calm waters.
• Hydroplaine is good because there is less contact with water which means less dragging.
• Shallow Vee is good in good in smooth waters and does not have much contact with water so less dragging.
• Deep Vee works well in rough waters because it can cut though but not very fact because it has contact with water.

Hull:

We decided to work with shallow Vee because in the pool, the water is not very rought and because if the speed. We started with a flat bottomed boat and added a V at the bottom. When trying it out, we found out that our V was deep causing the boat to slow down so we decided to remove the V. What influenced me to use the Shallow V is the information given on it.

Materials:

For the materials, we had a choice of using Acrylic and styroform. We used Acrylic for the body and filled the V with styroform. So our material use was influenced by the choices given and suggestions.

Propulsion:

For the propulsion, we decided to use sail cloth, ballon and propeller. We decided to use all this for speed. What influenced us is the need for speed and from our classmates. Some were using propeller, others sailing cloth so we thouthgt of combining everything together.
