How do you use trim tabs?

Most systems will be switch or dial controlled, used to deploy and adjust the tabs to the desired position. In most instances, you will first utilize your tabs on acceleration to get you out of the hole and up onto plane in the shortest time and with a minimum of bow rise. Tab deployment will push the bow down and assist you in adjusting your vessel ride to the optimum running angle, allowing you to see the horizon and what is in front of you. 

When up and running, trim tabs can be adjusted to level the running attitude (bow up or down) and roll (side to side) to find the best position for the given conditions.  This reduces pounding and spray in the cockpit, while optimizing performance and fuel economy.
