Lifters trim tabs for inflatables

lifters trim tabs for inflatables by MaxiMarine. An inflatable dinghy is an important part of any cruising boats equipment. The ability to move around makes anchoring almost as good as being in a Marina. However choosing an inflatable requires some trade off between size and storage space onboard. Large inflatables may be desirable but they take up too much space.

Smaller inflatables do not have the speed or capacity of larger ones nor do they have the smooth rides. Smaller dinghies lack the surface area for proper lift and without the length they bounce around in waves.

To help with performance Maximarine have developed trim tabs for the inflatable. First the extra surface of the trim tab adds to the planning ability and second the adjustment of the trim tab lets you control the attitude of the boat to the water. To help get onto a plane the trim tab lets the bow rise to climb the wave. Once on the plane Push the trim tab down to lift the stern and let the inflatable ride level

MaxiMarine’s Description

LIFTERSTM radically improve the performance of inflatable sportboats, increasing speed and acceleration 25% to 45% and planing weight capacity up to 30%, while decreasing fuel consumption by over 25%. Sportboats having insufficient power or carrying heavy loads can now plane or achieve higher planing speeds. Lifters are specifically designed and patented for sportboats with over seven years of development and testing to yield maximum performance with the following advantages:

The speed and weight carrying capacity of a planing hull is directly related to its planing surface area and driving power. Unlike small trim tabs, Lifters add more that 5 times the planing area, or a substantial 4.2 sq. ft. (12.5″ x 24″ x 2) of additional hull planing surface as shown on the right. At low planing speeds the additional surface area at the stern creates more than a proportional amount of added lift by pushing water down, opposed to the forward “V” section which pushes water to the sides. The additional lift far aft of the center of weight (boat, crew and motor) lifts the stern and lowers the bow for more hull planing surface area and upward lift rather than backward drag. Lifters also generate less drag and more lift then trim tabs by having a lower angle of deflection or attack and more surface area further aft. At high planing speeds when less surface area is desired because of higher viscous skin drag, the ventilation slots at the front of the Lifters suck air into the mini step which decreases the planing surface area and drag. This technology is similar to the latest side ventilated step and hull technology used on race boats but more importantly, Lifters dramatically increase the performance and comfort for fishing, hunting, scuba diving, tending, towing, rescue and other boating activities.
