Must agree with Macca here,
yes: the superwing mast is quite a soft and bendy mast
yes: it can stand up to a whole lot. The amount of bend and flick it can withstand in 25-30kts upwind is truly a remarkable sight.

But unless you rotate it, or any other mast to 90 degrees (ish) with a spinnaker up, you will eventually snap the thing in two - and cleaning up a rign that has fallen down with all the spinnaker lines etc attached is not a whole bunch of fun.
