New waterjet series for ferries, yachts and naval vessels introduced

This new midsize series enhances Wärtsilä’s range of stainless steel jets to include all sizes from 510 mm to 3,250 mm.  The new series is aimed particularly at the high speed ferry, high speed patrol craft, and customized yachting segments.

The new high performance Wärtsilä waterjets feature a number of significant competitive advantages and are designed for long-term, reliable performance. This is siad to be achieved through the use of high quality materials for structural parts, and the wide use of stainless steel in the jet construction. Although aluminium is a widely used and accepted material for jet fabrication, the Wärtsilä solution utilizes abrasion resistant stainless steel to conserve the carefully designed shape of the stator blades in order to retain high levels of fuel efficiency. The impeller and shaft are also constructed from stainless steel. These features not only deliver continuous high performance, but also notably reduce short-term maintenance requirements, as Wärtsilä states.
