An alternative warning light that can not be confused with any other would be to have
a light on the rotor tip /tips. The true hight of the rotor thus displayed and the movement could not be of anything else.
Thanks for your regular updates.Eddie..

How much do you recon that movement of the turbines will affect the wind? I don’t think this is an area that I would go out of my way to sail in – in fact if anything I would avoid it like the clappers. If you go into one of the mills, it is the boat that is going to suffer all the damage. I don’t like to think of how easy it would to assemble a helicopter rescue if you were to crash into one.

I am all for introducing green measure to protect the environment, but maybe if the government were to stop bombing the life out of Iraq, there would be less need for other more extreme measures – like putting up the price of Red Diesel!

Roxy..re: affect of the turbines to the wind..Having sailed through the farm off the Margate sands I can assure you that you will not notice any affect of them on the wind. Sailing from one corner to the opposite corner took 45 mins at a 4 knot pace. As for crashing into one, thay are quite big and visible from way off. The sands around there are far more dangerous.

Having only really experienced the one on junction 11 of the M4, my comments were speculation rather than experience. Thank you for putting me right.

Do you not experience any loss of wind while sailing past them? I would have thought they would have some effect.

We have sailed past the ones on Scroby Sands off Great Yarmouth. They are not a hazard to navigation as you would not want to sail across the sands anyway, and I think the rotors are so high above sea level, and move so relatively slowly, that they are unlikely to have much discernible effect on the wind at sail level. One interesting question is whether they are what planners term an "unacceptable visual intrusion" or a welcome navigational mark.
What do you think?
