IMTRA Expands Zipwake Offerings with New Series E Interceptors for Larger Vessels

New Bedford, Mass. – IMTRA, the leading manufacturer and importer of quality solutions and products for the marine, energy and transportation markets, announced today it has expanded its Zipwake Dynamic Trim Control System offerings with the new Series E line of interceptors. The Zipwake Series E is a family of large fast-acting interceptors perfectly engineered for bigger boats. The new product line evolved from the successful Series S that was designed for vessels from 20-50 feet. 

Series E includes three straight, three tunnel and two chine interceptors. When arranged to use the length of the stern for lift generation, the new interceptors are much more efficient at creating lift compared to narrow-span trim tabs. The large, modular design of the interceptors make them durable, affordable and particularly well suited for any planing or semi-planing boat between 40-100 feet. Capable of rapid deployment, the Series E deploys at a speed of 1.6 inches per second (40 mm per second) for a total stroke of 2.4 inches (60 mm).

In contrast to straight interceptors, the tunnel interceptor’s constant radius curvature allows for mounting above the propeller tunnel. The three tunnel models (R500, R600 and R800) have different radii, making sure that most large boat propeller tunnels can be covered with negligible deviation between hull and interceptor curvature. Chine interceptors provide a unique means of maximizing pitch and roll motion control by using the furthest outboard surfaces of the hull bottom for lift generation and roll reduction. 

Unique 3D controls with a large LCD display provide the helmsman with unmatched, user-friendly, intuitive and precise control of running trim, heel or heading. The system is fully automatic and significantly enhances the boat’s performance, fuel economy, comfort and safety. All interceptor models can be included as an option for new builds, installed as an aftermarket retrofit or added to expand existing Zipwake systems already in use.

“The Zipwake system has been embraced by boatbuilders, anglers and boaters looking for a comfortable ride and an efficient solution to trim control,” said Jamie Simmons, Zipwake Product Manager, IMTRA. “Larger vessels have their own unique design challenges and the Zipwake system has been expanded to accommodate these hull shapes.”

The Zipwake Series E will be available through IMTRA’s network of marine retailers, shipyards and marine retrofitters throughout North America in early January. For information on IMTRA or its entire product line, please call 508-995-7000 or visit
