Sanlorenzo has used the occasion of Boot Düsseldorf to announce its fiberglass planing megayachts and metal displacement yachts with either hybrid or diesel-electric propulsion. They’ll also have a distinctive model name, E Motion, to distinguish them from their traditional sisterships.
Sanlorenzo has already proven the E Motion concept in its lineup. In 2015, it launched an SL106 with diesel-electric propulsion. The shipyard says she consumes a maximum of 13 gph (10 lph) at up to 10 knots. In addition, it claims, battery power alone can power her hotel load at anchor for six hours.
The E Motion range will include both displacement hulls, built in steel and aluminum, and its faster planing yachts in fiberglass. Expect to see an SL86 E Motion launch in May, with a second unit launching in December. Sanlorenzo expects a few key advantages. Her full hotel load should operate overnight (eight to nine hours) at anchor without using an auxiliary variable-speed genset. Additionally, she should be five to six decibels quieter at 10 knots. Equally important, a power-management system will react in real time to the megayacht’s requirements. It will weigh things like the speed, hotel load, and even shore power if connected. This, of course, will positively impact fuel consumption.
As for the E Motion displacement megayachts, look for the 500EXP E Motion (at top) to debut in 2020. She’ll have azimuthing pod props, proven to be more maneuverable and have little to no vibration. Advantages extend beyond performance efficiency, too. The 500EXP will gain 199 square feet (18.5 square meters) of space aft. Sanlorenzo plans to use it for an “art gallery” engine room. A central walkway, flanked by glass panels, will let guests see into the engine compartments. Sanlorenzo further plans an internal stairway from the saloon to the beach club.
By 2021, the range will include the 58 Steel, 50 Alloy and 56EXP to provide superyacht owners with an even greater choice of environmentally friendly options.
