John, I just checked your page as I couldn't remember where you were from and I noticed you own a Commander and married a Connie!! My dad drove Chevy's and married a Caddie. He's no longer with me but your page made me think of him.  Thanks!

John, I own a 1977 41' flush deck according to my title work 410  I had some blue prints that came with the boat and I also ordered some from the museum I believe. they are on my boat 3 hours away. i will take snap shots of them and send the pictures to you to see if it will work.  If so I can try and have copies made but not sure the cost.

I've not seen that many boats and do not know what is typical.  The couple I've seen, it did not seem to ba a problem.  Very minor hairline cracks, but nothing significant.

Good luck, it is a great boat.
