Oceanvolts electric motor systems are now being offered on the J/88, a 29 ft state-of-the-art performance daysailer from J/Boats.

Imagine sailing on a beautiful day knowing that, even if the wind dies and you’re forced to turn on the motor, peace and tranquility are not lost. Every minute sailing, the battery pack is charging, allowing you to later silently power back to the harbor.

“There’s no quicker buzz kill for sailors than having to turn on the diesel engine,” said Jeff Johnstone, President of J/Boats.  “Most of our owners will tell you they sail their boats 90% of the time.  We would like to improve that other 10% and make it an environmentally-friendly solution for sailors who love the sea!”

J/Boats will install Oceanvolt’s innovative, fully integrated SEA system (Silent Electric Autonomy) on their first 2016 model J/88 to be launched mid-summer in Newport, RI. The boat will be displayed at the Newport and Annapolis Shows. The Oceanvolt electric motor system has full hydro-regeneration capabilities, meaning that you can create energy back to the batteries while sailing, with added passive recharging thanks to the high-performance Sunpower solar cells (the world's most efficient).

"For the past ten years, we have been developing innovative solutions for the electric/hybrid power market in Europe,” said Timo Jaakkola, President of Oceanvolt. “Based in Finland, a country renowned for developing leading edge ‘green’ solutions, our company has pioneered the use of electric power in keelboats that range from 15 to 60 ft and ranging from 3kW to 15 kW.  We look forward to working with the J/Boats team on their J/88 project!”
