Hi Richard
Thats a great result and is probably the first time I've ever heard of someone getting decent regen at those speeds.
170 watts at below 5 knots will more than handle house loads. (well it would easily do for me), and so that leaves some to recover propulsion loads. This is the kind of result that makes regen really useful and for a cruiser could mean they are truly independent for power needs.
What controller do you use? How did you measure this?
Cheers
Chris

Went out for a brisk sail on Monday in 12-15 knot winds. Alberg 30 with EY 100ibl system. We never went below 4.5 knots and mostly 5.5 knots upwind and 6+ downwind. We were getting 170 watts at 4.7, 230 watts at 5.5 and 300 at 6 knots.
Battery read 91% remaining when we shut down after putting the sails up. After 2 hours the battery was back up to the 53.35 reading that we left the mooring with after turning into wind to drop sails. For me this is usefull as it will easly exceed our house loads. Prop is a 13*12 3 blsde.
