Since the wing dont have a mainsheet, just an AoA adjustment, would it be a challenge to reinforce the wing for spinnaker use? All forces would have to go down the stays, but since the wing have a larger crossection than a mast.. Wouter?
I don't see a problem here. On conventional masts the bending of the top is necessary to get control over the draft and twist of the sail high up. Ergo the hound fittings can not be placed to high on the mast. Especially not since that aggrevated the bending of the mast in the middle (spreaders) where you actually don't want it to bend.
With a wingsail you can relieved of that necessity and so you can place the hound fittings at the spinnaker gate if you want to. As such all the spi loads will go down the stayes as addited tension and down the mast as compression; you have lost the much more damaging bend loads.
With this you just need to make sure the stays themselves and the attachment points on the hull can take the new loads and you are done. I dare venture that the basic 4mm 1x19 and attachment points I have now are sufficient to handle this already.
