Objectives

• The main purpose of designing was obtaining a
  boat which has the following characteristics
• Fast
• Light weight
• Cheap
• Easy to build
• - Strong enough to float

4
Problems/Solutions

• Problem Solution
• - Solid edge -
  Practice and study
• - Water coming inside the boat - Epoxy and
  fiberglass
