Maximize Trim With New Zipwake

By Rich Armstrong

Technological innovation can be found all over modern boats, so it was inevitable that evolution reached trim tabs.

Auto pitch

Say hello to Zipwake, a new "dynamic trim-control system" that promises faster, more efficient response that is fully automatic. The skipper no longer needs to tweak the helm controller while trying to set trim for optimal ride, according to the Swedish-based manufacturer.

Traditional trim tabs installed near the edge of the stern hull chine are essentially flaps that are horizontally raised and lowered manually with an electro-hydraulic control. Zipwake features multiple "interceptors" mounted flush to the stern. Interceptor blades emerge from the bottom of the interceptors, lowering straight down about 1.2 inches to provide trim. Deployment takes just 1.5 seconds. The manufacturer claims the efficient new way of trimming a planing or semi-planing boat are five to 10 times faster than traditional trim tabs with one-fifth of the drag, meaning better fuel efficiency.

The whole system is regulated by a Smart Ridge Controller, mounted at the helm, with built-in GPS, gyro, and accelerometer. The brains of the system automatically set the blades for optimal trim.

Arguably the best feature of the system is automatic roll control. The interceptors, coupled with the Smart Ridge Controller and GPS, maintain the boat’s desired pitch and roll angles. At speed, when the gyro senses the boat is rolling, the system automatically deploys the correct interceptor to offset the motion.

Zipwake delivers a more comfortable ride, better performance and improved fuel consumption – whatever the conditions, according to the manufacturer. Each interceptor comes in a kit for DIY assembly. Zipwake is distributed in the U.S. by Imtra, which will refer customers to a qualified professional installer.

Zipwake manufactures models for boats 20 to 60 feet. Prices range from about $2,500 to $5,000.
