LOOSDRECHT – The COVID-19 crisis hammered the Dutch economy in 2020. But that did nothing to stifle the Dutch marine sector’s drive for more innovation in electric boating.
A bird’s eye view of some eye-catching initiatives:
Waterdream, a builder and marketer of half a dozen luxury aluminum tenders of up to 52ft, has unveiled an electric version of its S-740. Powering the 7.35m craft is a Torqeedo Cruise 10.0 outboard and 4 Torqeedo lightweight lithium batteries of 3,500 Wh each. This lets the craft sail for up to 24 hours or 120km. The top speed is 12km/h. The S-740 is an existing Waterdream model.
Waterdream’s Bernhard van Oranje says “the electric motor is the ultimate in sailing! You hear nothing, but water. This adds a whole new dimension!” The company says all S-Line tenders can be converted to electric. www.waterdream.nl
The ECAT 1200 is the kind of boating Ariejan Kooy wants to do when he tires of sailing canvas. The marine engineer, formerly of Damen Shipyards Group, has drawn a 12.5 m electric cat with a 0.55m draft. He gave it twin Torqeedo Cruise 10R outboards that can be easily removed. The twin 10kW motors achieve an 8kn top speed and a daily range of 6 hours. The lithium-ion batteries are fed solar energy or shore power.
Each polyester hull holds a 2-person cabin up and a washroom. The port hull holds also 1-person cabin and the starboard hull a technical room. The salon has a galley and a steering position. The dinghy sits on a foldaway aft platform. Kooy has plans for 10 and 13m versions. He wants to hear from builders. Any takers? www.kooyacht.nl
Mastervolt has introduced 3 new Li-ion batteries. The MLI Ultra 12/2750, 12/5500 and 24/5500 are for use in tough conditions. Such as humidity, heavy vibrations and mechanical shocks. They are equipped for long-term, heavy repetitive cycles such as AC, pumps or electric motors.
The new batteries have a service life of 3,500 cycles at a deep discharge of 80%, more than triple the lifetime of traditional lead-acid batteries. Lithium-iron phosphate cells are combined with a Battery Management System. Full integration is possible for the CZone platform, MasterBus and NMEA 2000 protocols. www.mastervolt.com
WaterWorld has unveiled a powerful WW 15.0 engine for craft up to 12m. Its power compares to that of a 30HP engine. WaterWorld’s current range, sold in the Netherlands through De Stille Boot, comprises WW 4.0, WW 7.5 and WW 10.0 engines, with 4 to 10 kW of continuous power. The new WW 15.0 can have one or two props. A special feature: it can deliver 20 kW for a few minutes, for fast actions with extra power. All this still on a 48 volt power supply.
WaterWorld is growing fast, at home and abroad. Last year it opened offices in Norway and Britain. WW engines are already available through selected Torqeedo dealers in Germany, Austria, Switzerland, Denmark and France. More expansion lies ahead. www.destilleboot.nl
