Does anyone know the internal diameter (and even length if possible) of the scupper hoses used on a 1885 Catalina 27. Mine are so rotten, that they will completely disintegrate if I remove them and the boat is in the water - so I am definitely not anxious to take them off, check the internal diameter and wait for replacements. Catalina yachts does not have the information at this point - so I would like to make sure that I have the right size hoses before I take them off to get the ID. If it helps the hull number is 5916. The boat yard told me that they checked them two years ago - but obviously they didn't!! Any information gratefully received. Thanks.
