I have never had a gen on board, so I cannot comment on those. I would opt for the wind gen, assuming you get a good one, and that you also have a decent sized
alternator with external
regulator. Also, what size
battery bank do you have? From my perspective, you have a "boatload" of
solar already, so the wind gen would be icing on the cake. Wind and solar really compliment each other, when it is cloudy it is often windy. I wold guess that the only time you may need to run your
engine to charge batts would be in the summer, if you are using alot of power, and get some of those still days that are overcast.
Convert those halogen bulbs over to led, that will save alot as well.
We have a 35 footer, with all LED except for our chart light and som CCFL fixtures, which are just as efficient as LED. This includes nav lights.
Computers can be a big hog, if yours are lower power ones, that will help alot. We several, a pc and mac laptop that are power hogs, and a tiny atom based laptop and an android tablet that are miserly. I just built a 12v
low power PC for the nav station, we will see how that works out.
Have you computed your daily needs based on your
boat? This can seem like a waste of time, but it will help you get some idea of how much power you may need. You will never know for sure until you get out there, but it looks like you are the right track.
