Dowra,

Actually all the smart ass comments were because we don't know what
force we use hoisting the sail.

We hoist by hand and watch the sail. If it is windy there should be just
enough tension on the sail to just start to see vertical wrinkles appear
along the tack of the sail. No more than that. Putting the sail on
really means filling the space with sailcloth. That is what the
sailmaker designed the sail for. When it fills with air it will take the
shape it was designed for

Watch the wrinkles, vertical for strong wind (Ten and above) Horizontal
for light air ( Five and below)

If you are raising the sail with a drill motor, just put one turn on the
wench so that you can let the winch slip after the sail is correct. Add
the extra turns after the motor has stopped

I have a question? How do you set outhaul tension?

Hope I've helped.
