Hi Tim,
Great question! I have been trying for a long time to find all the owners! Yet I am still finding some that are pulled out of a shed!
My best advice is to talk with anyone who used to sail the boats! When you hear they sailed back in the early 90’s, Talk with them! Who did they sail with? Boats will slowly work there way to you. And even better, some of those folks may miss the 5O5 sailing so much, that they may want to come back out!
Keep working on it! The boats will surface!
Kind regards,
Paul
