have recently had the good luck to get a Columbia Yawl 41ft. I do not have any documentation or specifications on the boat. It will require an extensive renovation on the interior, ele/water/pumps,fuel systems,etc. Anyone who would be able to give advise where I can get the specs/layouts,diagrams , etc would be greatly appreciated. Will also have to replace top of the perkins diesel. Will be looking for a short block. Will have to replace the main boom and are thinking of going to a furling boom. Any suggestions? Thank you CLAUS
