AC discharge thru-hull: below waterline, or piss off my neighbours?

[GordMay]

Most manufacturers recommend installing the cooling water discharge above the waterline.

Ie:

Dometic:
The discharge from the a/c unit should then run to the seawater outlet thru-hull fitting which should be located where it can be visually checked for water flow and as close as practicable to the waterline to reduce noise.

Mermaid:
The "water out" thru-hull can be mounted any place on the boat’s hull that is a minimum of (6) inches above the water line.

Flagship:
The units' discharge through hull fitting should be between 4" and 8" above the waterline - if below 4" it would have to be treated as a "below the waterline" through hull and would be required to have a valve - above 8" the noise of the running water may be bothersome.

Thanks, Gord, aka "The Infomeister" (I say it with an Arnold Swarzenegger accent).

That was my shipwright's assertion: that it's important to be able to monitor outflow to know the pump is working. So, the trickling, possibly annoying to others, is a comforting sound to the owner of the trickle! [Insert erectile dysfunction joke here]
