Actually, I did have to reduce the -ve noseweight to about -5Kg, by moving the sheets as far forward as possible (not very) and adding weights to the front of the trailer and one bungeed to the rack.
All in all, interesting handling characteristics, and yes, I possibly could have tacked into the wind.
The observant may notice the grandpawagon in shot, which would have swallowed the sheets whole, but where's the fun in that?
