Wow, I''m 6''4" and have problems standing up in sailboats. I have admired the CSY 44 as well for the roominess and headroom. However, I just purchasedd a Bristol 45 that has 6''6" headroom. I have a friend that has a Morgan 46 and it has very nearly 6''8" headroom in the galley area. Trouble with headroom is that you begin looking at progressively larger boats. Ever consider power boats and trawlers?
