OK. At the risk of making a fool of myself, here's a crazy idea that I'm toying with. I am looking for any good reasons why I should NOT go ahead.
I am thinking of mounting a 2kW wind generator
with a 10 ft diameter turbine on a pole at the bow of our cat. The pole and gennie will only be erected during extended stays at anchor
The boat has dual back stays - one to each hull
- thus making mounting in the aft area problematical.
I plan to have a 10 ft pole on which the gennie will be mounted. This pole will be braced by two struts 90 degrees to each other, one running aft down the hull
and the other athwartships to the center beam.
The pole and struts will be mounted on bases using some method of quick release. Pole and braces will be tied down on deck
when not in use. So raising or dismounting the mast
should take less than 5 minutes.
One possible wind generator
I was thinking of is described here:
hybrid solar wind turbine - wind power turbines with solar and wind output
Stuff I don't know yet:
- How strong the pole and mountings need to be.
- Whether the turbine can easily be brought to a stop.
- How easy and quickly it will be to dismantle and stow away.
The bow mounting has some positive aspects - clean air at anchor
, low pedestrian traffic, lower perception of noise
& vibration due to distance. A large turbine even producing a small fraction of its rated power at low wind
speed will still be a good output.
It has negative aspects as well - mainly safety
issues. I don't know how quickly and safely I can get it down if I have to raise anchor and get going in a hurry.
