Looking for suggestions ?
I'm currently using a ducktape and attach with it one of the blades to the pole when away from my boat but not very happy...

I had a D400 on my last boat and did something similar with some string/line. I should have gone straight for the shaft, as over a period of month the pressure deformed one of the blades and caused an imbalance. If you use a piece of good line such as Dyneema around the hub and then over the body of the wind generator the forces will be on the main rotation axis and all of the props will have equal pressure on them in wind and you won't get an imbalance.
What sort of a windgenerator do you have? Some of them have electric auto-braking, and that might be a good thing to keep your batteries topped up during storage.
If your boat is on a mooring and swings with the wind, then tying the rear of the wind generator across the hull should be sufficient.

No doubt about it Zanshin, that is really clever. So for a swing mooring application a good addition would be to have a locating pin that sets the generator at 90 degrees to the axis of the boat......brilliant!!......and so simple.

Don't know about yours , but my air breeze has a switch (installed on the pole itself) to shortcircuit the generator so the blades only turn around very gently no matter what wind. It does not shorcircuit the battery at the same time However.

My is a airbreeze (Chinese) flavour and DO have the OFF switch and it actually seems to work well, but I'm little bit worried about very string winds where I am - St Cyprien/Gulf of Lion - from time to time it can go to F10 for short periods and while my berth is very sheltered still some gusts enters between the buildings... and I locking the windgen when I'm away seems a right thing to do...
thanks for the advices !

Vasko,
I am about to put my boat on the hard in Florida for hurrican season, and I will be taking the blades off of the Airbreeze while it is out of the water. I have an additional concern about debris where I am storing the boat, and my solar panels will keep the batteries charged, so it is easy to remove the blades.

Vasko, I am about to put my boat on the hard in Florida for hurrican season, and I will be taking the blades off of the Airbreeze while it is out of the water. I have an additional concern about debris where I am storing the boat, and my solar panels will keep the batteries charged, so it is easy to remove the blades. it is easy if the windgen is easy to access , in my case it is over the arch with the solar panel and I can't really reach the hub comfortably to be able to unscrew the blades... e.g. I will need to lower down the pole etc. which can be OK for long storage but for 3-4 week is not worth..
