Your main prop shaft or an auxiliary system?

These are reported to be excellent but pricey. 10 amps @ 5 knots and 40 amps @ 8 knots.

Off of the existing prop shaft ,mount a pulley and low speed alternator so it charges when sailing. People have used them for 60 years just trying to get some good new feedback from others. Cheers
