Hi Sami,

Can you explain your situation please?

I too am rather confused as to what it is you are trying to design or build. Is it one of these?

Or are you frantically trying to put one of these on your existing boat. If yes then you need to get to a sticky weekend sharpish

Maybe an alternative energy project?

If you clarify what you are looking at slightly I might be able to help... Im drowning in wingsail work at the moment

Never interested in building a plain before but shall we do one of those tri plains at the next sticky weekend.
I'll bring the balsa wood.
And how good would that windmill look ath the bottom of someones garden.
Clearly makes it too risky to get the lawnmower from the shed though.

Clearly the windmill is a cherubometer " If it is too dangerous to get the lawnmower out it must be cherub weather "  This also works the other way around.
