A pontoon boat is a type of boat that has a flat bottom and is supported by floats. It can be constructed using closed cylinders like pipes or barrels and can be used as a simple platform to create a raft. Pontoon boats are small, lightweight, and easy to handle, making them an excellent option for boating enthusiasts. To build a simple pontoon boat, you only need a few materials, some hard work, and a proper layout. Here are the steps you need to follow:

Materials required:

  • Airtight containers
  • A sheet of plywood
  • Wire or rope


  1. Place the airtight containers next to each other in a rectangular shape. This shape is the most stable for building a balanced boat.
  2. Ensure that the containers are empty and sealed correctly.
  3. Use steel wire or rope to tie the containers together, making sure they form a rectangle. Be sure to tie them tightly so that they do not float apart.
  4. Place a sheet of plywood on top of the containers. If you are using more than one plywood sheet, attach them together by nailing a 1-by-2 piece of wood across the top of the plywood boards to ensure that they stay in place.
  5. You can fasten the plywood to the barrels by drilling holes (four on each side) through the plywood and threading steel wire through the hole and around the steel wires holding the barrels together.
  6. If the pontoon is going to be used by swimmers, protect the edges with rubber to ensure that nobody gets hurt. You may also want to attach an inexpensive aluminum handrail to the pontoon [sources: Mademan, Four Pound Brain].

Always prioritize safety. Take all necessary precautions to ensure that you and your passengers stay safe while enjoying your pontoon boat.
