No sn, not at the moment.
I have found that the aluminium tube that the windsurfer booms are made of, slips beautifully over the tops of 3 of the masts and I made wooden plugs for them. One sail was a pin cap so just drilled a hole in the wood, super glued it in and drowned it in super glue to water proof it. (Red Dot super glue 7 tubes for $2.99 works as well as Loctite Super glue).
Took the fleet out yesterday for a run but there really wasn't enough wind by the time we got them all there and set up.
Got a few good runs anyway.

It sorted out what I had forgotten to do and what is need.
Boom heights that I thought were ok, under working tension ended up being way to low, so longer extentions needed.
I had also cut the sheet ropes too short on a couple of them restricting the sail movement. I just didn't realize that the sail would still generate power that far out the side. Unreal !!!!
A visitor saw us and he had a blokart with a 5.5 mtr sail and even he had to push it back in the gentle wind. The boys were keen and they all looked like they were using big wheel chairs, as they tried to keep them going.

Gota run.
