Does anyone have recommendations on a brand of UV water purifier?
There seem to be one heckuva lot of manufacturers and I'd like to weed

Dick,

UV does not "purify" water. With a high enough single dose, or constant
recirculation at a lower dose, you can "sanitize" water, and you can
break down dissolve ozone. With the amount of power you'd want to
consume on a boat, you'd be hard pressed to accomplish much with a UV unit.
