Fast Electric Yacht Systems (FEYS) announced the availability of its new Diesel Electric Propulsion System for yachts and small commercial vessels. The Invincible™ line of propulsion systems is available between 35 and 1400 kilowatts. The system, under development and testing for over three years at the company’s Houston facility, is the result of a joint engineering effort of Siemens, Cummins Southern Plains and SIPCO Motion Technologies.

A typical system contains one or more diesel generators to power electric motor driven prop shafts. Using standard inboard, stern drive or jet powered running gear and requiring no hull modifications, the FEYS system delivers remarkable results in reliability, fuel economy, noise, vessel weight, engine room space, installation time and reduction in preventive maintenance. The company suggests that pricing is less than traditional diesel power with lower total cost of ownership. The latest test vessel is a 40 feet re-powered express cruiser. Over 300 hours have been logged and the quoted results are remarkable. At a 25 knot cruise speed, the vessel’s fuel economy improved over 100% (.5 mpg to 1.2 mpg) and noise levels decreased from 89db to 84db at the helm.

This, combined with the fact that the system typically will use 35% less engine room space, reduces preventive maintenance to the boat owner by an average of 40% and costs 10% less than equivalent diesel drive.
