GLasstreams are built in Panama City, FL. They have just recently in the past 5 years or so started building bigger CC type boats. In the 80's-90's they mainly built single OB bass boats and ski boats from 14-20ft. I must say they're new CC line is looking pretty good.
Then again. Donzi's been in the business a while and they're hard to beat.
just my 2 cents.
