  1. Cardboard Boat Regatta Design (Part2):Full Scale Race Design Mr. Yersak Livingston High School Technology & Design 1

  2. The Problem: Design and build a floating structure to be tested by carrying two members of your team across the pool and back in the shortest amount of time.

  3. Specifications: Structure may only consist of cardboard and glue & duct tape provided in lab. Duct tape may only consist of less than 25% of entire boat. Material may not exceed 2 pcs. of 32” x 115” cardboard. Structure may be waterproofed with latex paint or by covering it in plastic. Structure must float Structure may not rest on the bottom of the pool when tested.

  4. Others odds and ends: • Only two of the three or four team members will be required to be in the vessel. • (So don’t panic) • Life Vests are MANDATORY • Life Guards will be on duty • No Swimming or people other than the teams in the pool at any time

  5. How will we know we have built the craft capable of holding your teammates???

  6. PLANNING & THE DESIGN PROCESS.

  7. Remember the penny barge? • What problems did we have? • What were the construction techniques? • How did we calculate total penny load?

  8. Boat Calculation Example • Weight your Team Members • Calculate to Team Weight: 640 lbs. • With 80 lbs. for boat added in

  9. Water Weight H20 H20 ±64 lbs. 1 ft. 1 ft. 1 ft.

  10. STEP 1: Calculate Water Displacement: • 560 lbs. team weight + 80 lbs. boat weight • 640 lbs. / 64 lbs. per CF = 10 CF of H2O displacement • (This is the amount of water the team and boat will push out of the way to stay buoyant in the water.)

  11. L X W = Area of Rectangle Base x Height /2 = Area of Triangle 5 Feet 8 Feet 2 Feet STEP 2: Calculating Water Line * Find the surface area of the bottom of your vessel *

  12. L X W = Area of Rectangle Base x Height /2 = Area of Triangle 5 Feet 8 Feet 2 Feet STEP 2: Calculating Water Line • Calculations: • (LxW) + (B x H/2) = SF • (5x8) + (5 x 2 / 2) = 45 SF • Volume of team displacement / floor area • 10 CF / 45 SF = .22’ x 12” = 2.67 in • Water line will be 2.67 Inches up the side of the vessel.

  13. Why could this number be less?

  14. Project Requirements: • Individual • Initial research questions • Brainstorm Sketches • Group • Design portfolio (you can access this on my website LHS Design Template) • Design & construct full scale cardboard boat • Calculation & evaluation worksheet • Testing Day in the pool!!!!

  15. Project Due Dates Full Scale Boat Completed (June14th) Design Template Due (June 14th) Test in Pool (June 19th – 21st) (Pending) Calculations & Evaluation Worksheet Due (June 24th)
