Aquair Tow Generator, issues with, durability of 2 weeks 1 day ago #3788

This question relates to the Aquair 100 tow generator. I am the owner of Tony Gooch's TAONUI and am preparing for a rather long, solo loop starting from San Francisco in the fall of this year (more here: www.figure8voyage.com ).

I intend to rely on hydrogeneration for the majority of my power and am about to close on an Aquair 100.

My reason for choosing this tech over the newer Watt and Sea, for example, is 1) cost and 2) a lack of room on the transom.

I have researched the Aquair and think it suitable to my power needs, but would be interested in others' experiences, especially as relate to dependability and durability (I will need it to work every day for the better part of a year) and any day-in-day-out use issues. For example, some think that the propeller being dragged is prone to being eaten by sharks, though my research tends to suggest this more a myth than a fact. I also wonder about wear and chafe on the tow line if used daily. Etc.

Many thanks in advance,

Randall

Hi Randall,
May I suggest you look at the DuoGen. We have used ours over the last 12 years, and in the water mode it is superb if sailing at 6 knots we make 8 amps on average. No danger of being eaten by sharks, no 30 metre line to tow behind. You should give it serious consideration. Price is more than Aquair Tow, but much less than Watt and Amp. The company also do a model just in water mode now I understand, eclectic-energy.co.uk
Good luck with the passage

Thanks for the thoughts, Brian. I've not considered the DG because I don't really want another hole in the transom and because the attachment seems weak for a vessel that will be spending several months in very heavy seas. Do you have any experience of the DG and its attachment in heavy weather?

You suggest trailing a line of 30m is disadvantageous. Why?

Best,

RR

Hi again Randall,
I have been using the Duo Gen since 2003. I am actually on my second one replacing a mark one with a mark 3. All products have problems over a long period of use. I had rebuilt the Mk 1 several times. Mk3 is now 4 years, and only replace bearings last year, We live aboard and so it gets a lot of use. I have found the attachment quite satisfactory whatever the weather and sea conditions. Recover out of the water is fairly simple I have recovery line I pass through a block to ease the job. I have heard that recovery of the Aquair is not easy with a long line. A friend did have his attacked by large fish (shark)? It bent the propeller, so that buggered it. He fortunately had a spare. I feel that the ones close to the boat are a vast improvement in power output and efficiency. Similar to a new generation, things have moved on. Have a look at the DG site. I see now they do a water one only, it seems to use the same components as the DG. I have found them to be a good company to deal with. Hope this helps.
Brian

I agree with comments on Duogen although I have only had one for 11 years - including 16 Atlantic crossings. Also service from Eclectic Energy has always been excellent.

Hi, we've just completed a circumnavigation with a Duogen. It works very well for us. Not too many issues or breakages even crossing the Indian Ocean. Not much drag either which I believe is an issue with the tow generator you're thinking of using. Also no holes in the transom, it mounts on your pushpit!
