I have been running a small dehumidifier much like yours in my 26 foot sailboat here in Melbourne, Florida for the past two months. The temps and humidity here have been terrible for the past month or so. I drilled a hole about 1/3 up from the bottom in the plastic reservoir and put it in the sink. I figure I can put a cork in it if I need to. Anyway, it is running like a champ! I closed off the nicro vent and the bilge has been dry for a while now. I think this was one of my "way better" ideas. Good luck with your unit.
