I was delivering a boat in yesterdays deluge. At one point there was a 3' thick fog on the surface of the water created by the rain splashing up. It totally obliterated any lobster pots and made them invisible. When the rain let up a bit you could see again. Also I can assure you that even Grunden's are 100% USELESS in rain like that. I was 100% soaked to the core even with full Grunden's foulies with a hood and boots....
