Their is a very active electric yachts yahoo forum where this has been discussed a great deal.
The consensus is that for most boats, even in light usage you would not have the room to fit enough panels to make that work.
Panels are used often to supply led lighting and to top off, the last 10 percent, charge all the time.
There was a showcase boat however recently that looked like an aircraft carrier, power only, that used only solar. It was a several million dollar experiment however.
