Hi Jan
I wouldnt have thought this design would be the best choice for a live aboard, even stretched. Theres only the nacelle for any real living area. Bernd will reply better than me but I recall looking at the drawings when Bernd first came out with this one as I do with all his new boats. Other small parts of your questions: the boat is trapezoidal so it is not asymmetrical hulled. It certainly is an interesting boat. Good luck
