The "Old School" layup is plenty strong. But a lightweight fully cored hull is stronger.

Rick, you were going to ask JC what the additional weight associated with the finished cabin was and how that extra weight would impact WOT. Whenever you get a chance, please let me know.
Thanks,
Ken

Ken,
I did ask John about the weight. Sorry I forgot to post it for you. It depends if you want the back rests with upper storage.
OK, Here goes.
Carpeted cabin with potti-approx: 250 lb extra
backrests on midship bunks with storage, carpeted and potti- approx: 350 lbs extra
You'll probably only loose 1 to 1.5 mph with the finished cabin

Rick

Ken !!
Misprint!!! 150 lbs. approx- carpet and potti
250 lbs. approx- carpet, backrests with upper storage and potti

Rick, essentially, there are 3 options? 1. The cabin pix you posted at the beginning of this thread have the backrests on the midship bunks. 2.The cabin without those backrests have the cushions on the v-berth but just jelcoat on the midship bunks? 3. No cushions on bunks or v-birth, just jelcoat.
Thanks,
Ken

Ken,
You can also get the cabin carpeted, without the backrests.

There are are actually 3 Y2K layups. Am I correct FX?
1) The 1000HP Race layup Y2K...i.e. JohnJr. FastEdy JCAP etc. ($$)
2) The Ultra Lightweight Special layup ( EXTRA $$$)
3) The Old Skool "Heavier" layup. ( .0$)

Your right Bash, But I think he was referring to 3 cabin layouts. We even have a sink and cooler for the cabin.

This may not be why he asked but:

The reason some people think of a "galley" and "head" and want it included is because if the boat is financed the interest can be wrote off as a second home. They are not very specific in what they require.

My last boat did not have this but as I look for its replacement I am going to keep this in mind.

If you want a galley, you got it !!
