Just wondering what others have done in regards to a solar charger for their 25. I have no battery (just put the boat in the water) - so any advice on that would be nice (I have no electronics...! Just cabin lights and running lights. Will install depth/speed/temp/fish finder type of thing along with MP3 player this winter). I have seen and read about 5 to 10w chargers. My concern is durability - been reading alot about products that claim they are waterproof, yet are not. So, what size battery (deep cycle) and what size charger?? Thanks.
