Hi Doug.
The website that you listed is for a re-seller of both Mastervolt and EMotion systems. While Mastervolt has a great reputation in the regular upscale marine electrical market. I don't think that we've had any first hand reports of a Mastervolt drive system from a member of this group.
EMotion http://electricmarinepropulsion.org/ appears to be using Solomon Technologies "Electric Wheel" drive systems imbedded in a hybrid system of their own design. I know that there a member here has a 40'+ catamaran with Solomon Technology drives installed, they were a factory installation.
I don't know of any marine drive vendors that are using AllTrax or Curtis controllers (but I'm pretty familiar with some of them from EV conversions), however, two of the regular drive vendors on this list, Propulsion Marine and Electric Yacht use Sevcon controllers in their drive systems. The Propulsion marine drive system that I installed uses the Sevcon Gen4 controller to manage a Motenergy (was Mars Motors) ME0913 PMAC motor. The Sevcon Gen4 controllers are much more advanced that the older Millipak controllers, properly configured, they run noticably cooler and have a more efficient throughput for PMAC motors.
You'll find that many of the auxiliary sailboats represented in this group have Electric Yacht or Propulsion Marine systems installed. Other drive vendors that have satisfied customers in the group include Advanced Marine electric Propulsion and Annapolis Hybrid Marine.
If you search previous posts on this list, you'll find a number of posts that describe the performance of boats that have converted to electric using these vendor supplied drive systems, including detailed performance data from my conversion. As I said before, many of these conversions are using Sevcon controllers.
Fair winds,
Eric
