http://www.slowboatcruise.com/. Is a much heavier boat with a single motor they get 4 knots just off the solar cells, quit a interesting blog I follow it pretty closely.
You have a lot less solar cells but will have over twice the electric power, so 6 to 8 knots should be very doable. The 40 mile range will be the part that takes some figuring. I'm doing a similar boat but have not got to the testing stage yet. So I don't have any real world numbers for you.
Hello EB Group
I look at my Trojan Yacht and think, well it may work. Let's give it a try!
So I'd like to ask you like-minded for tips and hints to realize this project.
My idea is to use the yacht for scuba diving and pleasure trips. I'd like to cruise at 6 to 8 knots and have a daily range from 40 nautical miles.
I want to use two 10 kW Mars Motors and let them run at 72 Volts. Battery storage is no problem once the gas engines are out! The battery charging is at the slip (110V) and while navigating 4 Solar Panels bring in a bit of extra amperes. A gas generator is on board too but it have to be fixed first.
The yacht is currently powered by 2 Chrysler 250HP gas engines. The length is 30.4 ft, breadth is 12.8 ft and she weights 16000 lbs. The propellers are 16RH16 and 16LH16 and the gear ratio is 1.52:1.
Thanks for your support and feedback!
Stephan
