Anyone experimented with adjusting the boom for different wind conditions?
Is there an ideal setting for up wind?
Or is the boom adjustment ineffective so not really a buying benefit?

Same as with Windsurfing sails. More outhaul for stronger winds and less for lighter conditions. Does make a difference. Stronger winds and flatter sail = better upwind.

That is my experience with my 4m Duotone wing.

I tried to adjust boom length of my Duotone 5m2 on the water when the wind increased to 25 knots and it was not easy at all.

Perhaps I am doing it wrong?

Dwight made a nice quick adjustable carbon boom for his duotone. Looks like a real good simple design.

Can the Duotone boom be easily bent or damaged on impact?

Impact would damage the much more fragile inflated wing.
But yes, run over by a car, the boom suffers damage.

Unless you are jesting, kind of improbable, I must say, for a car to smash into the wing while on the water ,( unless it is an amphibious car..)
I was thinking more along the lines of me falling over the wing's metal boom or the boom hitting the board when falling, as has already routinely happened to me when learning on a regular windsurding board..
Actually, the Duotone I am looking at has a slightly bent boom, because, the seller says, he used the wing on the snow and the wind load in these conditions is much stronger than on the water. This is why it bent slightly. He says this will never happen on the water, unless, perhaps, you surf in 30 knts...Just wanted to ..keep him honest..

Been using an old adjustable sup paddle shaft for 6 months with my duotone. Grip it up like a windsurfing boom. Works sweet, weighs bugger all.
