As the sailing season in the UK commences, we are very busy here
at Eclectic. Lots of yachtsmen and women have chosen DuoGen to provide
on-board power, and our order books are nearly full.
If you are thinking of having a DuoGen, get your order in now!
Whatever kind of vessel you sail, you need DuoGen.

DuoGen on smaller yachts |
The system was designed with larger boats in mind, but interestingly,
a lot of the early development work was done on my 20 footer
because she is moored on the River Trent close to our factory!
The short tower length machine would not look at all oversized
on a small boat and as most of the weight of the system is at
deck level, the overall adverse effect on stability would be
less than a smaller conventional machine on the end of a long
pole!
In water mode, amp for amp, drag is very much lower than with
systems that use tow ropes.
Smaller sized boats with a passage speed in the 4 - 5 knot range
would produce typical outputs of 4 - 6 amps in water mode. You
will note from our web site that output rises rapidly with boatspeed
and larger yachts would typically expect 8 - 12 amps with passage
speeds in the 6 - 7 knot range. The wind mode will of course
perform just as well on any size of yacht.

DuoGen on large catamarans |
| We have sold several DuoGens to owners of large catamarans,
and the system works very well. The principal issues to consider
are a) mounting and b) passage speeds.
Mounting - on monohulls, DuoGen installations are normally
braced and supported by existing pushpit steelwork. On catamarans
this steelwork is often absent, so a free-standing
installation needs to be made. This is readily achieved
using our universal mount kit together with two additional
and lengthened bracing tubes.
Normally, the alternator mounting or 'c' bracket is through-bolted
to the vertical face of the bridgedeck. This bracket also
carries the universal bracket which forms the upper tower
support.
The bracket is braced back to the deck using the bracing tubes
mentioned above.
Positioning the installation also requires some thought. If
you have dinghy davits on the stern, the DuoGen needs to clear
them and also be sufficiently clear of the hull so that it
can track laterally in water mode to allow for steering and
wave action.
Passage speed - the standard water impeller we produce is
optimised for the speed range 2 - 9 knots. If your catamaran
routinely exceeds 9 knots for sustained periods, you should
consider a reduced area, coarse pitch impeller. At 9 knots,
the standard impeller will produce about 20 amp output (12-volt
version), and some cat owners have reported outputs of up
to 30 amps at 10 - 11 knots.
The reduced area coarse pitch impeller reduces this output,
and moderates both drag and stress on the machine. This is
good to about 15 knots. One option is to carry both impellers
and swap them when you hit 9 knots! |
