Hello Talbot, we just bought a Catalac 9 M 1976 this last December 15. The hull is great but we still have some work to do. Our ''Let's do it!'' doesn't have a ''doghouse'' or ''wheelhouse''. By any chance does yours have one? If so could you please send us the measurements? We will build one after installing the new mast ( the previous owner had cut it in 2 because it was bended!!!) Luckyly a Catalac's owner from Norway had the blueprints for the mast so we will have build one with those specifications. By the way if you need those blueprints I can send them to you. thanks. Merci. Christianne
