Thanks for the responses. I am hoping to get away with just changing to the aluminum window tracks, my budget wont handle $6K for windows right now

I am seriously thinking about blanking some of them over and replacing with a smaller production type window. I know that may not sound very pretty, but I think I can work it out where it will look like a factory install. I'll let you see how this progresses when the time comes. I do think I want to keep the slider functionality for most all my windows, I like a breeze.
We are not making up our minds yet, but we are leaning towards removing the bunks. We will have to see how much use they get. I really like the idea of a laundry/utility/storage/fishing gear room. We think it will mostly be us (me and the wife) and another couple or us and a couple of our grown sons. I suppose daughter-in-laws and future grand babies can alter the best laid plans. It sounds like not having bunks doesn't hinder you guys.
Fish, thanks for the heads up on the spotlight, I hope you will share with us how you feel it is working out, the value for the money spent, and whether you would buy that again knowing what you know now. Additionally, thank you for the link to your boat layout. That helps me "see'' into your description and gives me ideas about space usage. That is very professional looking, well done.
Something new. I was at the mega-store and was looking at the pex plumbing supplies. Do any of you have experience installing this on a boat. I think this is the route I am going to take but I would like to hear pros/cons if you have any. I like the idea of installing an isolation manifold to control each of the hot and cold lines. I have big plans but I will probably take my time and do it right the first time... or so I think. Your thoughts on thiese types of subjects are valuable to me, I do hope you will continue to post your thoughts and observations.
Thanks to all

PS If your wives have any had any ideas on improving boating life my wife would love to hear them!
