Hey folks, I have a 1976 O'day 20 which I'm working on which has a small tube running between the cockpit sole and the hull that has been rednecked over the years,and it works but is terribly ugly under my main hatchway.My question is this; Does anyone have any pics of how the original system was arranged? What is there is basically a small through deck fitting at the bottom of the hatchway which meets a possibly 5 inch peice of plastic tubing that goes down to another throughull fitting at the aft end of the centerboard trunk,and te penant goes through all this to the board. I really would appriciate any photos from the time period of O'days in this size range.
