The unit I have drains into my bilge. I have an automatic bilge pump
, so the water isn''t a problem for me -- I only run the unit while hooked up to 120v ac so any drain on the pump
is handled by the battery charger
. The dimensions are on the link --- as I recall it''s about a 15" by 15" footprint, and 30" high. I have it sitting on the aft berth of my Catalina 34, venting thru a solar vent directly above it. ... we sleep on the salon berth and V-berth, so this compartment is storage on our boat. As for venting out the hot air, there is a vent hose about 5'' long, and they say you shouldn''t extend it much more than that -- back-pressure, I guess. email me direct if you have further questions.
