Mr. Miller?

Did the way that the wings were attached ever change?

At any rate, change tha shrouds, trapezez, forestay and bridles at minimum, you don,t know how old they are. Use white lithium grease to lube the rudder cams, check the bolts that hold the rudders on, lube or replace the O rings on any inspection ports and the same for the hull drain plugs. inspect all sheets and halyard for signs of deterioration and you should be set to sail.
