Zipwake Dynamic Trim Control System is a fully automatic trim system for boats. It helps you get on a plane faster and keep your boat level. Your boat gets better performance, improved comfort, lower fuel consumption and enhanced safety. To do this we use fast-acting interceptors instead of conventional trim tabs and an easy-to-use control panel with built in gyro sensors.

Both interceptors and trim tabs redirect the water flow to control pitch and roll. Where they differ is that Zipwake interceptors enter the flow vertically and extend only 30–60 millimeters, whereas trim tabs often project 150 mm.
Due to its size trim tabs can damage lines in the water and easily be damaged when docking. Therefore interceptors are often preferred by fishing, lobster, pilot, and other commercial boats.
Zipwake’s interceptor blade extends 30/60 mm, whereas trim tabs often project 150 mm reflecting substantial drag.
MORE EFFICIENT LIFT
Near full beam interceptor arrangements are much more efficient at making lift compared to trim tabs with narrow span.
Interceptors provide more effective trim control creating less waves which directly leads to better fuel economy
5 TIMES FASTER ACTUATION
Zipwake’s blade stroke takes 1.5 seconds, outperforming conventional trim tabs by at least a factor of 5.
The Zipwake interceptors are installed below the waterline on both sides of the boats transom. The control panel is installed at the helm and the distribution unit should preferably be installed on the inside of the transom.
The Zipwake Dynamic Trim Control System works on planing and semi-planing boats up to 100 ft. We have the Series-S for boats up to 50 ft and Series-E for boats up to 100 ft. Although there are exceptions so don’t hesitate to contact your distributor for advice.
The Zipwake system allows up to six interceptors, three on each side, but in many cases two or four interceptors will get the job done. We recommend a minimum of 30 % of the width of the transom to be covered but find that installations with 50 % or more perform optimally. Fill out the Zipwake questionnaire to determine how many interceptors you’ll need on your boat and consult with one of our distributors for the best result.
Yes, see the Reference section for examples of Zipwake installations on aluminum hulls. Zipwake also have the Adaptor Plate product that simplifies installations on aluminum hulls with protruding bottom plate.
The answer is yes. The Zipwake system minimizes wave resistance and saves fuel. The average is 4% to 9% in fuel savings when using the Zipwake trim system versus running the boat without Zipwake. The result will vary due to different boat types and sea conditions.
Because of the small blades of Zipwakes interceptors – 30mm for Series-S and 60mm for Series-E – the drag created is minimal. Zipwakes interceptors creates more lift on the transom than they do drag through the water which results in a slight gain in speed.
The lift force generated by the Interceptors increase quadratically with speed, hence the amount of lift increased significantly the faster you go. From what speed the built up lift helps getting the boat up on a plane depends ultimately on the installation, where best performance is achieved with interceptors spanning the full beam (Z-factor = 1), but typically from 8-10 knots.
When using the AUTO mode you can use the pitch control wheel on the control panel to add a pitch offset to get the bow up or down. The pitch offset is a temporary adjustment, but you can permanently store an offset to the pitch control curve by press-and-hold the control panels roll wheel. This can be done at some different speeds to achieve optimum performance. It is also possible to examine and edit the curve in the control panel menu. Here is a video covering this in more detail.
The system can be operated in MANUAL or AUTO mode. The AUTO roll control can enabled/disabled by a quick press on the AUTO-button (toggle between Full AUTO and AUTO Pitch). The Pitch Control can be customized to optimize performance, either permanently by adjusting the pitch curve or temporarily by applying pitch offset. This way the effect of Pitch Control being turned off can be achieved.
Yes, with the Integrator module you get the same functions as you would with the control panel in your MFD.
Zipwakes Integrator module is compatible with selected models from Garmin, Raymarine, Simrad and Navico.
It is possible to monitor Zipwake data on MFDs like Simrad NSS. Zipwake transmits data of interceptor (trim tab) position, rate of turn, COG&SOG, and attitude (pitch, roll, yaw) on the NMEA2000. Refer to the MFDs operator’s manual on how to set it up to display NMEA2000 data and what data the MFD can receive.
