Sounds like the 20s were a definite improvement to the 19, but arent they really about the same length? Ive seen posted numbers running 19' all the way to 20'7" for a 19

The blue 19 CC is advertised with a 60 gallon tank. Im guessing thats about as big as you can shoehorn in there and a definite plus, but the tanks werent/arent boxed in with the stringers? Is that the "one piece grillage" system Ive seen in pictures? Is that in the 19?
