Vessel #1 was traveling downstream at approx. 25 mph.   Vessel #2 had just come down off plane and was drifting.  At some point both boat operators saw the each other, operator1 tried to take evasive action and turned left. He hit boat2 and ramped it causing damage to both boats.  It appears the poor visibilty due to heavy rain and fog caused the two boat operators not to see each other till the very last minute.  Photos and operator statements have been attatched.
