[Euro Cruiser]

I've always been unimpressed with the idea of using raw water to cool a reefer system when fresh water from an onboard tank is available. And relying on fresh water makes use of the reefer possible while on the hard; in fact, we were just doing that in Lisbon last month while in a shipyard.

There are several types of custom built hardware that allow heat transfer using a thru-hull or external hull fitting...but I don't see the logic for incurring that expense when a few feet of vinyl hose and some 'T' fittings can provide infinite fresh water cooling from one of the boat's tanks. And isn't it on this BB somewhere that a contributor pointed out his new 2" ID Frigoboat thru-hull that incorporated cooling passages for his new reefer was not properly grounded and was about to fail due to galvanic corrosion?
