James,
With the motor mounted under the seat in the dinette of the Catalina 30 seems like an optimal installation, very clean. Where are your batteries? Your performance numbers look good for a 30' sailboat. I hope that I can come close to those figures with a full keel and a prop in an aperture.
Fair winds,
Eric

> The motor draws 25 watts in idle mode and starts the propellor turning at 50 rpm at 50 watts. The electric drive consumes 1500 watts at 3 knots and 4 KW at 5.2 knots.

> We are now entering into the optimization stage of installing the drive. We will be monitoring DC current and voltage, AC current and voltage, motor rpm, propellor rpm and temperature of all components. We can change the motor windings, the gear ratio, and the propellor to create the most efficient system for the boat. Efficiency is so important because higher efficiency means longer range.
