Everyone wants to know the answer to the question: "How fast and how far can I go with an electric propulsion system on my boat?" This is a complicated question to answer, so the purpose of this page is to document and share performance data on various electric marine propulsion systems, with various size motors and power storage, on various types of boats and conditions, in order to establish realistic expectations for these systems. Instinctively we know that the bigger motor, the bigger batteries and the lighter and smoother hull you have, the faster and further you can go. However, all boats are different and there are trade-offs so in order to give boaters more confidence in their ability to get where they need to go on the water under electric power, we present a better idea:
Boat name (owner), boat type, displacement, EP system, voltage, battery AH, propeller
Propulsion: Power Vs. Speed
Case 1: Bianka (Capt Mike), Nonsuch 30, 8 tons, Thoosa 9000, 48 volts, ?, ?
Case 2:
Case 3:
Case 4:
Case 5:
Case 6:
Case 7:
Case 8:
Case 9:
Case 10:
Regeneration: Power Vs. Speed

As of April 16, 2012 this page is a work in progress. If you have data to share, please send it in any file type in the format described above to: Greg@ElectricSeas.org and we will convert it into a photo file for easy viewing. It is expected that an " average picture" will clearly emerge from the data and we will be able to describe the "typical boat." It will be interesting to see if and how many case studies diverge from the average. From these divergent case studies we will hopefully be able to gain insight and learn how to make improvements to all of our electric boats.
