Ventilation is the key to keep the moisture and thus the mold/mildew under control. Add a couple of solar vents like the Nicra, set one to pull and one to push at opposite ends of the boat. Prop up cushions and open lockers when you leave. And keep your bilge dry.
I have mold / mildew allergies and those things are enough for me to have avoided problems so far.
