The main idea with trim tabs is to be able to push the bow of the boat down so to get the best ride and actually use the V in the bow to cut through the waves. On some boats you can trim the engine in enough to push the bow in, but this changes the engines thrust from pushing you forward to pushing the stern up to plant the bow. It makes your efficiency go way down because instead of pushing the water straight back, your now forcing it to push the water downward to hold the bow down. With tabs you can keep the engine trimmed for peak efficiency which helps with milage, using less throttle, less strain on the engine, and since it is running at a better angle it stears easier. Then you can adjust your tabs to get the boat to run at the best angle for a smooth ride. Also they help you to get on plane and stay on plane at slower speeds which really helps out in rough weather.
