Systems Trim Tabs Ensure trim tabs are completely retracted when backing the boat. Damage to the trim tabs may result otherwise. Hydraulic Trim tabs (Figure 3-15) help adjust the vessel trim for weather, cross-winds, and water current conditions. In addition they are used to adjust for listing due to uneven loading and propeller torque. The trim tab system consists of: • Electromechanical Actuators • Stainless Steel Trim Tabs • Tactile Control Switches A trim tab operators manual accompanies the documentation package you receive with the boat. It is your responsibility to become aware of it’s contents and the proper operation of the trim tab system. Remember that it will take practice to understand how the various trim characteristics will affect your boat. Figure 3-15. Trim Tab 3–22 Chris-Craft
Systems Theory of Operation Trim tabs are used to modify the running angle of the boat. The Chris-Craft is designed to plane at a particular speed and weight distribution. As weight increases and/or speed decreases, the stern settles creating an inefficient, untrimmed condition. In this bow-high position, visibility is limited, fuel economy is poor and wake is large. Additionally the hull bottom may be pounded by waves. Trim tabs allows the vessel to plane at heavier loads and slower speeds than the designed planing speed. Increased trim may improve the ride in a head sea by allowing the bow to cleave the waves, rather than pound over them. In a following sea, the tabs should be fully retracted for maximum steering response. A listing condition may be corrected by applying more trim on one side. Too much trim will increase the drag and cause the bow to “dig in” allowing wave action to veer the boat. As the owner/operator, it is you responsibility to understand how trim tabs affect the characteristics of the boat. The Trim Tab Owner’s Manual that accompanies this vessel provides additional operating and safety instructions, which is not repeated here. However at a minimum: • Use trim tabs only at cruising speeds. • Do not use more tab than is actually needed for good performance. • Do not reduce the running angle less than 2°. • Do not use the trim tabs when backing or running an inlet. Damage to the actuators and tabs my result. • Fully retract the trim tabs when trailering the boat or if leaving the boat to sit in the water for any extended length of time. • Spend time getting familiar with how the trim tabs affect the vessel. • Improper use of the trim tabs can cause an accident and/or injury. Trim Tab Control Switches There is a trim tab switch for each trim tab (Figure 3-16) and are generally located on or near the helm. When pressed, the switch activates the pressure pump that moves the trim tab in the desired direction. Actual location of the switches may vary from model to model. To correct for a listing condition you must lower the trim tab on the listed (lower) side by pushing the top half of the rocker switch in a half second burst until the boat is righted. If the stern of the boat is highly loaded, use both switches to operate both tabs, which lowers the bow when the boat is on plane. Figure 3-16. Trim Tab Control Switches Chris-Craft 3–23
