I have a Hydrovane that came with the boat, and have always had good customer service when I have needed parts or advice from the Curry family who run http://www.hydrovane.com/
Partly because of that I bought an echo tec water maker from them about 18mnths ago.
Last week I had a bizarre problem with the watermaker (nothing to do with the watermaker, just circumstance, the unit has been excellent).
I was in Florida, and just about to set off when the problem was discovered late in the evening.
I sent an email, and by the next day Will Curry had identified the problem, last seen 15 yrs ago.
Although he was in Canada and the parts I needed were in Trinidad he organised priority shipping at no charge and no charge for the parts. Two days later the parts were with me and we were on our way again.
The Curry family are ex-liveaboard cruisers, so appreciate the logistic problems we sometime have.
No connection with the company etc....just a very happy customer.
