Thank you for the quick reply. I removed the screws that held a small bilge pump in place in the stern water trap that the previous owner had installed and water started coming up through the inadequately sealed holes. I use 10 pounds Calcium Chloride in my 34ft boat over the winter and all of it gets used up so i figured it would be a very affordable attempt at removing some (not all ) of the moisture in the foam. I have also read about an individual that routinely uses calcium chloride the dry out boats (Boston Whalers) that he restores and confirms this by weighing before and after. What is your opinion on the effect of removing a core of foam on the structural integrity of the hull?
Thanks again for the feedback
