I have indeed heard of them.
They seem to be nearly as reasonable as they say they are.
A friend had one on his big crusing catamaran and said it was useless....the cat was too fast and the unit used to try skipping out of the water, which eventually stressed the hose.
He eventually bought a monohull (36footer, ben Lexcen design from before he changed his name to Ben lexcen, sorry, don''t remember it any better.)
anyway, the boat had one of these water-logs already on board. He tried it as part of the sea trials and found it worked brilliantly!
Seems that boat speed is a critical factor, as is the length of tow (not sure how much hose they supply as standard, but sometimes he said he needed to reel it in to less then 20 feet to get good performance).
For myself, I think that this is the only kind of watermaker we can seriously afford, both in terms of cash, onboard space and power requirements...but I am a little hesitant about any life-giving tool that works by being trolled behind the boat like a lure. I can just see my $3000 water maker gettign chomped or snagged and the hose/rope parting while out in the middle of nowhere.
They do not float, so just going back for it is not an option, and the enite unit spins, so attaching a secondary lanyard of some sort is also not an option.
I guess I would be happier with a design where the major watermaker cylender stayed bolted to the aft deck and the propeller could be towed along on a drive-rope like the old tow-along generators. At least that way you can only lose a bronze prop and some rope, But the unit does not "suck" the water to deck height and needs to be fully submerged.
Feel like a gamble????
P.S I tasted the water from one. Very flat and not all that pleasent...but it will keep you alive and it was not salty (would be great for showering, as soap made it lather like anything)
