Son of a son,
Your last post came out while I was posting.
There's a good Cheoy Lee web site. Some Cheoy Lees are under ballasted in my opinion. I don't remember the ballast ratio of the Cadet. Divide the ballast weight by the total displacement. Over 35% is good, closer to 40% is better in that size range. Some Cheoy Lees are under 30%.
27 feet is not too big, in my opinion. I'd say it's about right.
