Captain 20 was on channel 20 and was a nerdy looking guy with fake Spock ears and futuristic uniform; he played even worse stuff than Captain Chesapeake -- think Ultraman and the like.
'Full Disclosure' is not a show, but a disclaimer I sometimes put on my posts.
Sorry to say, I do not remember Buddy Dean.
The highlight of Captain Chesapeake was the screenshot of the waters of the Chesapeake Bay behind him, artificially rocked around to try to make it look like the in-studio set was bobbing aboard a boat. One day the folks moving the film of the water got a bit carried away, and it turned upside down for a moment.
Cheers!
