Twin Engine Propulsion

Efficient Performer

Performance, draft and safety influenced the decision to choose twin engine propulsion

The mission from the outset was to develop an offshore vessel that provides the most economical performance possible. Diesel/electric propulsion was considered as well as a single engine installation. The diesel/electric option was ruled out due to the much higher initial cost. Surprisingly the single engine option proved to be less economical at low and mid-range speeds and no better than the twin engine configuration at higher speeds. After analyzing the data, The twin engine propulsion option was selected as the main power source of the Outback.

The selected twin engine configuration also provides the security of redundancy of engines, running gear and rudders. Twin engines also allowed Michael Peters Yacht Designs to reduce the draft by more than a foot and the additional security of having the keel become the lowest point.
