Your boat is a 1972 GL-20. There was never a hydrostream model. Hydrostream is a whole other boat company. I am a third generation Switzer and I too have a 1976 GL-20 just like yours that I just fully restored. Good luck getting $3000 for it in the existing condition. Yes the GL-20 is a rare boat, but depending on how much work one needs to do you almost have to give it away. I had to redo my keel, A-frame, stringers, transom, all new paint, etc. It adds up quickly. Hopefully it finds a good home.
