Aloha Steve and Linda,
We are building a 65′ Catamaran and trying to get as much of our electricity needs from solar and hydro. We chose a Duogen turbine but so far haven’t found a way to install it in a cat. Then I read that you used a shaft generator in one of your vessels in your cruises around the world. Can you tell us the pros/cons of the system and if it could be installed in a Cat. How much power should we expect from the shaft generator? we are running a 24V system in our boat.
Mahalo for your help and safe sailing.
With a cat and all the deck/house area I would opt for solar instead of a shaft generator which is draggy (you need a fixed prop) and noisy. Lots of details on this in our Offshore Cruising Encyclopedia.
