I am the original owner of a 1987 21' Bahner open-bow I/O. It's been a great boat and I've tried to take good care of it. Unfortunately, the passenger-side windshield was recently broken (a passenger used it as a hand-hold), so I am now in need of a replacement windshield. The plastic is now 25 years old and is getting foggy, so it doesn't look that great anyway.
I would love to find out who the original manufacturer was, and would call Rod Bahner to find out, but don't know if he's still around or not.
