Introduction and query from a new member to the group:
"Thanks for the Welcome. I have a Nonsuch 36 which I plan to re-power this summer. As part of the investigation of options, electric propulsion has been discussed. I look forward to opinions on electric propulsion systems (AC/DC), components, designs, manufacturers/companies. Below are a few questions and how I expect to use the boat in the future.
Question #1 - Can you propose a system with a generator that will automatically engage when the battery bank needs recharging to properly operate.
Question #2 - Do manufacturers/companies provide a system configuration diagram for owner installation. Does the diagram include a bill of material. Are cable and lug connections stipulated.
Question #3 - Do manufactures provide system weight by component.
Question #4 - AGM vs Lithium batteries and solar panels
Questions #5 - Are there any dangers associated with electric propulsion
Question # 6 - 48 Vs 72 Volts I expect will provide great range. Are there any other consideration.
Background on Nonsuch
Below are specification and planned use for our Nonsuch 36. Using the existing V-drive what system components can you propose. Assuming 75% throttle is a safe and efficient operating range for the Ocean Volt system, in this application on a Nonsuch 36 how many knots of speed can be sustained. For example on prior trips to Maine we have traveled for 30 -35 hours under power at one time. Please provide a summary of component weights and cost.
Future Use: Coastal cruising including Trips to Maine, VIRGINIA and potentially Florida. I will be retired soon and expect to use the boat extensively.
Boat Specs:
1) Weight -19000# with cruising gear
2) Hull Speed 7.8 (during inclement conditions travel at near hull speed would be desired)
3) Feathering Propeller
4) V-drive is Hirth unit
5) Current power Westerbeke 58 HP Diesel
In advance thanks for your help in educating me on the options for electric drive."
