Matt
Check out Wakespeed, then you'll want to put them in touch with Max Cruise.

Diesel Engine, Electric Motor.

Looking forward to seeing your hybrid setup! Is your one diesel engine still going to have a high output alternator or is the electric motor attached to that diesel the only way to generate electricity from the diesel engine?

Lol, my kids bought me one of those titles.

Interesting discussion, Matt and Jess.

For my boat, I will use diesel-electric propulsion - a tested and tried technology - since the late 19th century (1880 something). One can save a whopping 30+% fuel, because there´re no longer a RPM to torque mismatch.

If one doesn´t like the electric part of diesel-electric propulsion there´s another option, which is hydraulic.

One should avoid doing many conversions, because otherwise the total efficiency drops - fast. That means if one has a dead/malfunctioning combustion engine, but plenty of electricity, one should not use electricity to spin the hydraulic pump, but instead use an electric motor to turn the propeller shaft.

Interesting solutions, hope you can sell the spare engine for a good price. I guess wind strength and angle will be a big factor in speed and power consumption. I think Terry deserves a credit for his work developing and testing the systems.

You covered weight distribution, weather, cruising range and lifestyle, prop type and size, hybrid option(s), spcl. speed/power/torque/rpm, regen, augmenting battery size and location. Any projected broad cost comparison options for this boat size? E.g.: 2 full electric engines, 2 diesel engines, 1 new diesel hybrid & 1 new electric engine, 1 used hybrid & 1 used electric engine, 2 diesel/electric hybrid engines. Cost to be separate or include props/fuel tanks/battery bank and auxiliary equipment.
Down the road discussions about noise, heat, fuel, comfort, reliability, maintenance, ease of maintenance, parts availability, redundancy, maintenance work area space.

We are an electric Bristol 35, suggesting you put extension hoses on the two grease nipples, lubricating the fore and aft bearings, making routine maintenance much easier.

If those figures stand up and I'm sure they will, it looks like the best of both worlds. Max Cruise have shown beyond doubt they have their customer best interests at heart and i hope they get a ton of business because of it. On a side note, I bet having an argument with Matt would be very frustrating because of his methodical and detailed approach to everything… which is a good thing in my book! … Stay Safe & Fair Winds!!

Man, you create excitement, good job going through all this hybrid set up. Can't wait until you guys go to sea.
