How do you properly tie a canoe to a car roof for safe transportation?

To properly tie a canoe to a car roof for safe transportation, follow these steps:

1. Place foam blocks or a roof rack on the car roof to protect both the canoe and the car.
2. Position the canoe upside down on the roof, with the bow facing forward.
3. Use cam straps or ropes to secure the canoe to the roof rack or foam blocks.
4. Make sure the straps are tight and secure, with no slack or movement in the canoe.
5. Double-check all straps before driving to ensure the canoe is securely fastened.
