It would help if Mr. X said how big a battery bank he had. He needs a minimum of 300 amp-hours IMHO, if he is going to try and stay off the grid. That would give him an operating cushion, should he run into some Seattle-type weather...
The 120 Watt solar panel will generate about 40 amp-hours per day. THe AmpAir 100 Wind turbine's output is a bit hard to guess since it is really dependent on wind speeds in the anchorage.
Chances of FRYING any battery bank is very high without using a charge controller of some sort. A breaker and digital amp meter is probably going to cost almost as much as an inexpensive charge controller. The cost of the charge controller is going to be paid back in the cost of batteries saved by not over-charging them. A good MPPT-type charge controller will also increase the effective usable output of both the wind gen and solar panels.
I'd add stupid to Mr. X's description, since it is foolish to try and do something like this without investing in the proper equipment IMHO.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
