SD8.6 installed on a Maestro 40 sail yacht

The Maestro 40 sail yacht is a semi-light displacement cruising boat built on the Finnish west coast. The boat owner was seeking a propulsion system to drive the boat in and out of harbors and to be able to motor in windless situations.

Oceanvolt SD8.6 saildrive system was a perfect match for the boat. The SD8.6 has enough power to allow maneuvering in tight spaces. The regeneration function also allows the skipper to charge the batteries while sailing. A useful feature on longer voyages when the boat’s appliances can all be powered from the propulsion battery.
