Contour Trimarans?

Does anyone know Contour Trimarans well?

I have a customer that is trying to correct the aka alignment on a Contour. The aka on one side of the boat it at a different angle than the other side. Upward movement is controlled by 3/8" diameter water stays that oppose the rig loads and keep the aka from folding upwards under load. There does not seem to be any provision for adjustment of the mounting tangs and the water stays are fixed length (Aircraft Eye to Aircraft Eye).

Before we go adding turnbuckles to a system that was designed with no adjustment, is there somewhere on the boat that should get a good hard look? I can't imagine that the basic alignment depends solely on the water stays.

Can anyone offer any suggestions?

 

Quick follow-up.

My customer added the turnbuckles to the water stays and says the boat has never sailed better.
