Re: Ct 48
Life... Kaluvic has not been active here since 2010 and is unlikely to see your question.
Bob Perry, the designer, however, does stop by now and then and could definitely answer your question. I expect the ballast is encapsulated in the hull molding, however it's possible that they used a bolt-on 'shoe' or section of the keel itself. However this is unlikely to be the full chord length of the keel and therefore probably won't reduce the overall height of the tow. You'll need to build up your post count but after 10 or so you might try sending a PM to Mr Perry.
