Preheat oven to 350 degrees F and spray two 9x5" loaf pans with non stick spray.
In a bowl whisk together sugar, eggs, vanilla and oil. In another bowl whisk together flour, baking soda, powder, salt and cinnamon.
Slowly incorporate dry into wet ingredients until mixed. Shred zucchini on a few paper towels, fold over the top and press gently down to absorb excess water.
Gently fold in shredded zucchini and coconut into batter. Pour equally into the 2 loaf pans and bake for 40-45 minutes. Check doneness by inserting toothpick into center. It is done when no wet batter remains and only crumbs are attached.
Set on cooling wire rack for 10 minutes before sliding out.
** If you want to use the batter to make muffins, bake for 18 - 20 minutes or until the top springs back when gently touched in the center.
