Where should the condensate drain be directed for an air conditioning system installed at the waterline in a wooden powerboat?

The condensate drain for an air conditioning system on a wooden powerboat should be directed into a sump that pumps overboard above the waterline to ensure proper drainage and to prevent any potential water damage to the boat. Directing the condensate overboard above the waterline protects the vessel’s interior from the risk of flooding and moisture accumulation that could occur if water were to drain into the bilge or other areas where it could remain trapped.

By discharging the condensate above the waterline, you also reduce the possibility of backflow, where water could potentially enter the A/C system or the vessel due to rising water levels, especially during docking or mooring situations where the waterline could change. This method is compliant with marine safety regulations and ensures the longevity of both the air conditioning system and the wooden structure of the boat, which is prone to degradation if exposed to excessive moisture over time.
