Re: [Electric Boats] SOLAR & WIND NUMBERS

I really don't have any sage advice to offer.

From what I have read my guess is that you will be just fine.

Based on my own experience I like to be able to monitor what amps I am pulling and the voltage of my bank at all times.

I think it you have that capability you can more readily make judicious decisions on when you run the electric and for how long.

Thanks Capt Mike,

I am still conflicted. I have only a mooring in Marblehead, MA. The electric option feels like it will serve the bulk of my needs - primarily day sailing. My issue is for the vacation trip or long weekend and having to rely solely on turbine and panels for recharge.
My sloop is only 30ft with a displacement of 8500lbs. I have a paranoia that electric will meet 90% of my needs and wont be there when I need it most. Am I nit picking?

Then I think about adding a genset. I am very confused and need to decide shortly as I have a fresh hole where my old MD 7 once puffed.

Thanks!

There was no real wind so charging for most of the afternoon was primarily via the 60 watt solar panel. In the evening a line of thunder storms came through. The Marine AirX wind generator kicked in about 1 to 1.5 amps only in the higher gusts. After the storms passed the wind died again. The next day there again was no wind. So charging was again primarily solar. By 4pm about 26 hours after I returned to the mooring the XBM was registering 99.5% capacity. I hope this helps when thinking about adding solar and wind charging systems.
