I think you would find the V-berth to be long enough for you. I'm 5'10" and it is good for me. I have only tried it out and not slept over night in it. The V berth gives much more space than my Catalina 22.
The keel weight is probably less than 200. I have carried it and moved it around before we got it on the boat.
I have never reefed the sails on the boat. I have found it to be a very stable boat and I enjoy the heck out of it.
I just added a MinKota 45 electric motor for a kicker and took off the 3.5 hp motor and put that on the Catalina.
I think it is best if you can try these boats out before buying them to make sure they are right for you. Of course I bought both my boats without sailing on them first.
