Some pet bottles on the bottom of the boat, and some on the side of the boat. Also, make sure you prioritize the lower half of your boat to tape your pet bottles. You can tape as many pet bottles as you want. The more pet bottles you tape, the more your boat floats.
Step 6: Covering Your Boat in Plastic Wrap
Try to be as accurate as you can with the cardboard measurements, and keep the cuts and folds as precise and clean as possible. Too many measurement errors will make it more challenging to assemble the boat and may even impact performance. While you don’t need to be an expert, make measurements with care. Make use of scraps or smaller pieces of cardboard for practice to understand better how to cut and fold properly.

By using the board, make a rectangle that is 1mx1.5m. Use a box cutter to arrange the shape, and use duct tape to connect it together. Use a measuring tape to check the length and width.

In the picture above, the inside part of the boat is not covered by plastic wrap but if you have enough, covering the inside part of your boat will help a lot too. Make sure you tape from the bottom even on the inside of your boat. The deck was one of the simplest parts we just traced the hull onto another piece of cardboard than added an inch out from the the perimeter of the boat.
Guide to Making a Cardboard Boat
In a guide to building a sturdy cardboard boat, the website Instructables offers a formula. Sixty pounds displaces about one cubic foot of water. Start by adding up the weight of your crew, then divide by sixty. That provides the cubic feet of water you can expect your boat to displace. You’ll want to choose dimensions for your boat that roughly multiply together to get that number. More complex cardboard boat designs would make use of smaller cuts and folds, usually for inserts that help reinforce the structure of the cardboard boat.
When that's done, you do a similar thing that you did on step 3. But, next, you have to make a rectangle that is 1mx0.6m. When you got the 2 boards, place them in layers and connect them with duct tape.

After making the necessary cuts, attach the bigger pieces together using tape, then reinforce them with other materials such as glue or what materials are allowed. Scale down the measurements of your boat and build a small boat using the same design with a manila folder. Set it on the water with a few rocks to simulate having passengers aboard. It is one of the best ways to build a cardboard boat. Study the free pattern carefully before embarking on the project. My recommendation of where to tape pet bottles is in the picture.

You can get them from recycling centers or local stores. Tape is highly recommended but as you know, there are different types. To make you forget about your doubts, a race using cardboard boats was held in Cyrus Peirce Middle School. There were hundreds of participants who all enjoyed the event.
I was fortunate to be on Larry Eisinger's team. Larry was the true father of the home-improvement movement. He was a veteran of WW II, a pilot, and after surviving the war he moved to Staten Island, NY getting involved in the publishing industry. CLICK or TAP HERE to see a huge selection of many of the books Larry either authored, co-authored, or edited.
Corrugated cardboard may be used, but it cannot have any wax, resin or vinyl coating. Decorations can be made of any material, but should not help the boat stay afloat or keep its structure together. The chances are high that this cardboard boat building activity will be done outdoors, but it’s a good idea to use a table, even a makeshift one.
With the figure 30 cubic feet, we will determine the positive buoyancy we want. This refers to the waterline and how much of the boat we want sticking out of the water. Having half of the boat out of water is 50 percent so multiply 30 cubic feet by 50%.
