SR - the trip was a BUST. You are right about the cold weather turning them off. Highest water temp we saw was 42 degrees. Saturday it snowed about 2" while we fished. We rode all over the Atlantic Ocean only to catch one, ONE stinkin fish that wasn't even a keeper. It was a suckfest. Our buddy boat managed to catch 2 barely keepers and a throwback. It was fun though. Had the Mr. Heater crankin inside the enclosure. We stayed very warm. We actually had 2 Mr. Heaters with one as a backup but we ran "twins" occasionally.
