My Colgate 26 that I bought new recently came with a Uni-Solar solar
battery charger (Model #USF-5). I use my battery for
lights,
VHF radio and thats about it. Their web address is: www.ovonic.com/unisolar.html, and their phone # is 1-800-843-3892. In my owner''s manual they show 3 models. Mine is the smallest. It just hooks right up to the 12 volt battery via a cable. I just lay the charger on the deck where there is sun. No regulator is needed for my setup. It says in the manual that you only need a regulator if "the rated peak charging current in amperes, of the Solar
Battery Charger is less than approximately 1.5% of the battery capacity, in ampere-hours..."
The model that I have is specified as a "maintenance charger". The next model up (USF-11) is a "power source for weekending,and coastal cruising..."
Good luck.
Rob
