We are newbie sailors looking to buy a used boat (34'-40') for coastal cruising in New England with friends who have sailed more in warmer climates. One of us has asthma and all the boats we have seen (all in colder months) have had mold and mildew in the cabin. I was wondering if there are sailors out there who have asthma and can comment on dealing with mold on a sailboat that is used about once every 1-2 weeks. Are there things that can be done to minimize the problem or manage it? I've called a cleaning/detailing company and they said they can clean the cabin for $600-$800 and if needed remove any ductwork and clean it for about $1600-$1800. Do you think this would deal with the problem? Would it come right back? Thanks for any advice!
