Hi Alex, I haven't seen any evidence that there was a tank on Expresso between the hull and the liner. Perhaps that was an option or the first owner did it. The idea of some sort of forced ventilation is a good idea. I'm not sure I like the idea of going through the deck, however. There was a great article in Practical Sailor within the last 6 months on this subject. I'd recommend you read that, it's very informative. I will try to find the article.
