Dynamic Trim Control
Imtra’s Zipwake dynamic trim control system manages your boat’s running trim, heel and heading. Designed for planing and semiplaning boats from 20 to 60 feet (inboard, outboard, sterndrive, pod drive or waterjet), the system incorporates “interceptors” to provide lift. Blades of differing sizes allow a nearly full-beam arrangement, and each extends just 30mm into the water, minimizing drag. The blades deploy in 1½ seconds, five times faster than conventional trim tabs, according to Imtra. Each kit includes one pair of straight interceptors. $2,375 to $2,925.
