Determine the dimensions of the boat based on the size of your crew. Plan to keep the width of the boat between 24 and 32 inches 61 and 81 cm wide, depending on how many people will sit abreast to paddle the boat.

Use solid lines to indicate folds and dashed lines to indicate cuts. Then, build a small version of the boat out of cardboard. Test it in a sink or basin full of water and note if there are any problematic parts of your design.
For example, if your finished boat will be 10 ft by 3 ft by 1 ft, switch the units to inches to make the boat smaller but keep the model proportionate�make your model 10 inches by 3 inches by 1 inch. Fill the model boat with coins or rocks that are proportionate to the weight of your crew to ensure it will float.
